Nano Matrix Soft Confectionary for Oral Supplementation of Vitamin D: Stability and Sensory Analysis.

Vitamin D deficiency distresses nearly 50% of the population globally and multiple studies have highlighted the association of Vitamin D with a number of clinical manifestations, including musculoskeletal, cardiovascular, cerebrovascular, and neurological disorders. In the current study, vitamin D oil-in-water (O/W) nanoemulsions were developed and incorporated in edible gummies to enhance bioavailability, stability, and patient compliance. The spontaneous emulsification method was employed to produce a nano-emulsion using corn oil with tween 20 and lecithin as emulsifiers. Optimization was carried out using pseudo-ternary phase diagrams and the average particle size and polydispersity index (PDI) of the optimized nanoemulsion were found to be 118.6 ± 4.3 nm and 0.11 ± 0.30, respectively. HPLC stability analysis demonstrated that the nano-emulsion prevented the degradation and it retained more than 97% of active vitamin D over 15 days compared to 94.5% in oil solution. Similar results were obtained over further storage analysis. Vitamin D gummies based on emulsion-based gelled matrices were then developed using gelatin as hydrocolloid and varying quantities of corn oil. Texture analysis revealed that gummies formulated with 10% corn oil had the optimum hardness of 3095.6 ± 201.7 g on the first day which remained consistent on day 45 with similar values of 3594.4 ± 210.6 g. Sensory evaluation by 19 judges using the nine-point hedonic scale highlighted that the taste and overall acceptance of formulated gummies did not change significantly (p > 0.05) over 45 days storage. This study suggested that nanoemulsions consistently prevent the environmental degradation of vitamin D, already known to offer protection in GI by providing sustained intestinal release and enhancing overall bioavailability. Soft chewable matrices were easy to chew and swallow, and they provided greater patient compliance.

Optimization and modelling of the fracture inhibition potential of heat treated doum palm nut fibres in phenolic resin matrix polymer composite: a Taguchi approach

The chemical treatment of natural fibres for its surface modification for the development of polymer composites is popular but it comes with an adverse effect of a chemical change of the fibres. In this study, the surface modification of natural fibres (doum palm nut (DPN) fibres) with low-temperature heat treatment (30 °C–75 °C) has been reported as an alternative method to the treatment of natural fibres for the development of polymer composites. Taguchi method of the design of experiment was employed to determine the effect of temperature and fibre content on the mechanical properties (hardness and fracture toughness) of DPN fibre-reinforced phenolic resin polymer composite. The process showed that the best combination of fibre content and fibre treatment temperature for optimum hardness and fracture toughness and results proved to be at 5% and 75 °C respectively. Statistical analysis established the significance of heat treatment in improving the fracture toughness of DPN fibre reinforced phenolic resin composites. Physical observation with scanning electron microscope and Fourier-transform infrared spectroscopy confirmed the improvement in interfacial bonding between the fibre and the matrix with the increase in fibre treatment temperature without a change in the chemical properties of the treated fibres. The study concludes that the treatment of fibres with temperature is an alternative and effective method to the chemical treatment.

Effect of co-addition of SiC and WC on the densification behaviour and microstructural evolution of TiC-based composites

In the present study, the effect of simultaneous incorporation of SiC and WC additives on the densification behaviour and microstructural development of TiC-based composites is studied. Four different TiC-SiC-WC (TSW) composites with varying SiC and WC content were synthesized by ultrasonic wet milling followed by spark plasma sintering (SPS) at 1750 °C for 5 min under 40 MPa external pressure. The average particle size of the ultrasonic wet-milled mixture underwent an appreciable refinement from 2.48 μm (un-milled powder) to between 0.9 and 1.25 μm. The sintered compacts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and thermodynamic assessment. All TSW sintered specimens exhibited a relative density of greater than 98% with TiC +10 wt% SiC +15 wt% WC reaching the highest value of 99.2%. The XRD analysis and microstructural evaluation confirmed the in-situ formation of Ti3SiC2 compound for specimens TiC +15 wt% SiC +10 wt% WC and TiC +20 wt% SiC +5 wt% WC as suggested by the thermodynamic evaluation. Besides, except for specimen TiC +20 wt% SiC +5 wt% WC, some of the SiC grains with unclean grain boundaries were found to be dissolved partially within the (Ti, W) C solid solution, thereby indicating the formation of (Ti, W, Si) C solid solutions as confirmed by the SEM/EDS analysis. The optimum hardness and indentation fracture toughness of 22.43 GPa and 6.54 MPa m½ were obtained for the samples TS10W15 and TS15W10, respectively. Crack deflection, branching, and bridging induced by the untwine SiC grains, partly un-dissolved WC particles, and (Ti, W) C solid solution phase are among the main toughening mechanisms responsible for improving the fracture toughness of the co-reinforced specimens besides the break of intertwining SiC grains.

ADDITIVE MANUFACTURING PARAMETERS OPTIMIZATION OF Ti6AL4V ELI FOR MEDICAL IMPLANTS

Additive manufacturing (AM) of titanium (Ti) alloys has always fascinated researchers owing to its high strength to weight ratio, biocompatibility, and anticorrosive properties, making Ti alloy an ideal candidate for medical applications. The aim of this paper is to optimize the AM parameters, such as Laser Power (LP), Laser Scan Speed (LSS), and Hatch Space (HS), using Analysis of Variance (ANOVA) and Grey Relational analysis (GRA) for mechanical and surface characteristics like hardness, surface roughness, and contact angle, of Ti6Al4V ELI considering medical implant applications. The input parameters are optimized to have optimum hardness, surface roughness and hydrophilicity required for medical implants.

Microstructures, mechanical properties and corrosion resistance of TiN/AlN multilayer films

TiN/AlN multilayer films with different modulation periods (Λ) were prepared by RF-reactive magnetron sputtering. The microstructures, mechanical property and corrosion resistance of TiN/AlN multilayer films were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), nanoindentation and electrochemical comprehensive tester. The results show that the TiN/AlN multilayer films are composed of face centered cubic (fcc) TiN and tightly packed hexagonal (hcp) AlN. The multilayer films are coherent epitaxial growth as Λ increases from 2 to 12 nm. The hardness and the corrosion resistance increase with Λ increases from 2 to 12 nm. The optimum hardness is 29.27 GPa and the strongest corrosion resistance displays with Λ = 12 nm. The coherent interface could be destroyed, and the alternating stress field as well as the hardness decreases sharply during the modulation period of 26 nm–36nm. The self-corrosion potential decreases and the self-corrosion current density increases. The corrosion resistance of the film decreases with Λ increase from 26 nm to 36 nm.

The Effect of Plasma Nitridation on Surface Hardness of Titanium Alloy (Ti-6Al-4V) for Artificial Knee Joint Applications

Nitriding has been carried out using plasma nitriding techniques for surface treatment of Titanium as a biomaterial component. The purpose of this study was to determine the effect of plasma nitriding on surface hardness that occurs in titanium. The material used is Titanium Alloy (Ti-6Al-4V) Grade 5 which is processed by plasma nitriding by varying nitrogen (N2) and argon (Ar) gases of (100% N2/0% Ar), (95% N2/5% Ar), (90% N2/10% Ar), (85% N2/15% Ar), (80% N2/20% Ar), and (75% N2/25% Ar), and temperature 400ºC, time 5 hours and a pressure of 1.6 bar.

Obtained a hardness of 371 HV/VHN or an increase of 159% of the raw material with hardness value of 143 HV/VHN

Study on mechanical characteristics of the nano-TiC reinforced Al6061 metal matrix composites

The purpose of this study is to determine the wear mechanism of Al6061 metal matrix composites (MMCs) under the influence of different proportion of titanium carbide nanoparticles (nano-TiC). A sophisticated rotating tribometer was used to conduct wear testing on the prepared specimens in this study. The base material chosen for the study is Al6061, and the reinforcement has been identified as nano-TiC. Matrix alloy composites were made by stirring nano-TiC into Al6061 matrix, and applying it as a reinforcing particle. The wearing characteristic of the produced composite was investigated using an upgraded rotational tribometer. The weight percentages of the nano-TiC reinforcement were calculated as follows: 3%, 6%, 9%, and 12%. The micro - structural characterization of Al6061 MMCs demonstrates the virtually uniform mixing of reinforcements. It has been discovered that increasing the weight percent of the reinforcement upto 9% percent resulted in greater rigidity. The wearing rate was discovered to be a consequence of the sliding speeds and weight percent of the reinforcements in this investigation. With increased slide velocities, the wearing rate was noticed to be increased, significantly. The optimum hardness and wear resistance values are found at the reinforcement of 9% nano-TiC in Al6061 MMC.

A Critical Review on Heat Treatment of Aluminium Alloys

In the modern world, smart materials play a vital role. There are many methods to improve the mechanical and material properties, one among them is by reinforcing different materials into aluminium. Without reinforcing the material, properties can be altered by heat treatment. Age hardening is done for the aluminum and its alloys. Only 2XXX, 6XXX, and 7XXX are heat treatable. The Al2024 alloy is solution heat-treated (T3&T6) with different temperatures and aging exhibits optimum strength and hardness due to the presence of coherent Guinier Preston (GP) zones and ultrafine grains of Nano-sized S-phase (Al2CuMg) precipitates. Hardness can be improved by coating technique later persisting with artificial aging, restricting the cooling rate and heat transfer. The Al6061 is solution heat-treated (T4&T6) and artificially aged; here Al6061 alloy is treated with T4 results in higher formability but lower yield strength whereas T6 treated results in lower formability but higher yield strength. The tensile strength and yield strength of the Al 6XXX series vary accordingly 6005 > 6106 > 6063 > 6061. The 7XXX series alloys are treated with precipitation hardening which improves stress corrosion cracking, hardness, reduces ductility, and ultimate tensile strength. To overcome SCC retrogression and re-aging, which has similar microstructure precipitates of T6 and over-aged T7 condition, Double aging > RR > T6 condition methodology. The current work has the collective details of the effects of heat treatment on aluminum alloy and its composite material.

Optimization of casting parameters for improved mechanical properties of eggshell reinforced composites

Abstract The tensile strength, hardness and toughness of any materials are the most important mechanical properties in the selection of materials for varied industrial applications. In the development of aluminum based composite material, tensile strength and hardness were significantly improved by adding various ceramic reinforcement particles. However, toughness was reduced. In this research work, an attempt was made to enhance tensile strength, hardness and toughness simultaneously by using carbonized eggshell as reinforcement material developed via electromagnetic stir casting. The process parameters used in this study are the matrix pouring temperature, wt.-% of the reinforcement; preheat temperature, stirring current and stirring time. Response surface methodology (RSM) is used for conducting the experiment. The multi-objective optimization technique utility theory is employed to optimize the combined mechanical properties viz. tensile strength, hardness and toughness. Microstructure results show that at the optimum level of process parameters, eggshells are uniformly distributed. Confirmation tests are conducted to validate the experimental results. Experimental results revealed that at optimum process parameters, hardness and tensile strength are significantly improved without affecting the toughness property of the composite. The optimum level of process parameters to enhance all mechanical properties (tensile strength, hardness and toughness) were found to be a reinforced preheating temperature of about 448.32 °C, a stirring current of about 11.64 A, a stirring time of about 63.64 s, a maximum pouring temperature of about 800.24 °C and a percentage of eggshells of about 9.16 %. The novelty of this work lies in the fact that no attempt was made to optimize these electromagnetic process parameters. Corrosion loss, thermal expansion behavior and a wear test were investigated to observe the effect of adding eggshell at optimum electromagnetic stir casting parameters.

Prediction of the optimum heating duration for potatoes in steam convection ovens

Steam convection ovens (SCOs) can be used in food service facilities to boil various foods and soup. It is important to determine the required heating duration based on the number of cooking pans and weight of the ingredients. In this study, the relationship between heating duration and three factors were investigated: (i) number of cooking pans, (ii) total weight of the samples and water per cooking pan, and (iii) ratio of samples to the total weight. Changes in the center temperature and hardness of the potato were predicted based on the measured water temperature during heating at a combi mode (100 °C, steam saturation level 100%). The optimum heating duration (Θ) until the sample reached optimum hardness was calculated. The finite element method was used for these calculations. A multiple regression equation was obtained, in which the time until the water temperature reached 98 °C (tw98) was the objective variable and the three factors were explanatory variables. Moreover, the relationship between tw98 and Θ was expressed using a simple regression equation. Based on these results, it was possible to predict the Θ from the values of each factor. Thus, the prediction of optimum heating duration with parameters (i)–(iii) was easily facilitated.

Effect of shot peening on the surface properties, corrosion and wear performance of 17-4PH steel produced by DMLS additive manufacturing

Components produced by additive manufacturing (AM) via direct metal laser sintering (DMLS) have typical as-fabricated surface defects. As a result, surface properties of AM products should be modified to increase their strength, anti-wear behaviour, and at the same time to ensure their high corrosion resistance. Surface modification via shot peening is considered suitable for additive manufacturing of medical devices made of 17-4PH stainless steel. The objective of this study was to determine the effect of shot peening pressures (0.3 MPa and 0.6 MPa) and three types of blasting media (CrNi steel shot, nutshell granules and ceramic beads) on the tribological characteristics and corrosion resistance of specimens of DMLS 17-4PH stainless steel. Results demonstrated that shot peening caused steel microstructure refinement and—except for the nutshell shot-peened specimens—induced both martensite (α) formation and retained austenite (γ) reduction. 17-4PH specimens peened with steel and ceramic shots showed the highest increase in surface hardening by approx. ~ 119% (from 247 to 542 HV), which significantly improved their wear resistance. The highest mechanical properties (hardness and wear resistance) and corrosion resistance were obtained for the surfaces modified using the following media: ceramic beads > CrNi steel shot > nutshell granules. Adhesive and fatigue wear were two predominant mechanisms of tribological deterioration. Results demonstrated that the application of shot peening using ceramic beads led to grain size refinement from 22.0 to 14.6 nm and surface roughness reduction, which in turn resulted in higher corrosion resistance of the material. DMLS 17-4PH specimens modified by shot peening using ceramic beads and a pressure of 0.6 MPa exhibited the optimum surface morphology, hardness and microstructure, and thus improved wear and corrosion performance.

THE EFFECT OF ECAP PROCESSING TO HARDNESS, SURFACE MORPHOLOGI, AND CORROSION RESISTANCE OF 6061 ALUMINIUM ALLOYS

Al-Mg-Si alloys (6xxx) has been widely used as structural materials in building and vehicles because of its excellent strength and corrosion resistance. The improvement of fine grain microstructure which can increase mechanical and physical properties become an interesting field in recent research.. Equal channel angular press is the most promising method to apply severe plastic deformation (SPD) which can produce ultra-fine grain in the bulk material without residual porosity. This study presents some experiments results on the effect of ECAP number of passes variation to the hardness, microstructure, and corrosion behaviour of Al 6061 alloys. The samples were annealed in the furnace with argon gas environment at 530°C for 4 hours and then immersed in liquid nitrogen for 5 minutes before ECAP process. The ECAP process was done with Bc route using dies with 120° of internal channel angle and pass variation of 1, 2, 3, and 4. The optimum hardness is 107.58 HRB in Al 6061 samples with 3 passes of ECAP. The increasing ECAP number of passes leads to a significant grain size reduction from 0 way pass, the grain size is around 10 µm, while for a 4 way pass, the grain size is around 2.5 µm. The corrosion resistance of Al 6061 alloys increased with the increasing number of passes in ECAP process.

Wear performance of Ni-Cr-B-Si hardface coatings fabricated by cold metal transfer welding

Nickel-based thick hardface coatings are employed in nuclear power plants because of their superior wear and high-temperature resistance properties. Unfortunately, fabrication of a crack-free coating with less dilution is difficult using the conventional hardfacing techniques like Plasma Transferred Arc (PTA), Metal Inert Gas (MIG) etc. A sound coating having optimum hardness and better wear resistance property is essential for reactor applications. The current work aims to investigate the wear behaviour of Ni-Cr-B-Si hardface coating deposited on 316LN stainless steel, where metal-cored filler wire was used as a consumable in the Cold Metal Transfer (CMT) welding process. The hardface coating was characterized for its hardness and microstructure. Apart from that, pin-on-disc wear tests were performed using the extracted pin specimens from the hardfaced substrate. From this experiment, a micro-hardness of 531.24 ± 73.15 HV0.5 was measured across the coating cross-section. The microstructure analysis revealed the presence of precipitates like borides and carbides in the coating. Further, a specific wear rate of the order of 10−14 m3/Nm was found from the wear tests. Confocal microscopy on the worn surfaces of the pin specimens revealed, the surface damages mostly occurred by ploughing and fracture. The investigation ensures that CMT can be used for depositing crack-free, low dilution and wear-resistant hardface coatings in nuclear industries.

Gas Tungsten Arc Welding of Stainless Steel 304 and 202 Grades for Optimum Weld Bead Width and Hardness Value

Gas tungsten arc welding of two different stainless steel grades of 304 and 202 of 3 mm thickness is attempted through this experimentation to produce the weld joint without any weld defects. The pure argon is supplied to protect the molten weld pool from any form of contaminations. The welding factors like weld current and travel speed are chosen to prepare the welded joints. The response surface central composite experimental design is used to draw 10 numbers of welding conditions. The gas tungsten arc welded butt joint is produced in a single pass manually for complete penetration. The ranges of weld current are chosen as 86, 90, 100, 110, and 114amps. The welding speed is set as 1.54, 2.05, 4.64, 5.09, and 7.5mm/min. The welded sheets are evaluated for weld bead width which is measured with the help of a Vernier caliper. The hardness of the welded joints is also measured. The chosen factors and measured width of the weld bead and hardness value of the weld joints are analyzed by the use of different statistical terms such as R square, ANOVA analysis, lack of fit, t-test, F-test, and effect tests to state a regression expression at 95% assurance level. It is thus understood from the regression analysis that the welding current and travel speed having major influences upon the weld bead width and hardness of the welded joints. In the manual welding technique, both factors are supposed to be carefully matched by the welder otherwise the penetration depth and proper formation of weld bead width are quite difficult to obtain which further increases the total heat input leading to the degradation of mechanical properties. The current experiment is performed to get an optimum condition by optimizing the weld current and speed to get a well-formed weld bead structure by controlling the total heat input. Thus the experiment will be useful to get the desired quality gas tungsten arc welded joints which are most essential in particular for aerospace and automotive industries for various structural applications.

Experimental investigation on stir casting of a metal matrix composite material

In this article, Al7075 matrix with SiC as reinforcement particle was developed and the mechanical properties such as tensile strength, hardness, and impact strength was investigated. Aluminum is preferred as a matrix phase because Al alloys have low density and good ductility. Silicon carbide is chosen as a reinforcement phase due to its brittle and hard properties to enhance the wear properties. Mechanical properties of aluminum metal matrix have been tested at different temperatures and holding time. It shows an ultimate tensile strength of 121 N/mm2 at 800°C processing temperature and 20 mins of holding time. At a processing temperature of 850°C, it shows maximum hardness and impact strength. Among all the fabrication processes, stir casting is chosen because stir casting process is the simplest and cheapest for fabricating metal matrix composites (MMCs). Microelectronic and aerospace packaging industry requires a material with optimum hardness and impact strength to prevent the material from wear and impact during material handling. These MMCs will be a replacement for traditionally used materials such as W-Cu, BeO, and Kovar in packaging application.

Effects of Sintering Variables on the Physical and Mechanical Properties of Metal Injection Molding Molded 17-4 PH Stainless Steel

Metal injection molding (MIM) is a near net shape manufacturing technique for producing small, complex, precision parts in mass production. MIM process is manufacturing method that combines traditional shape-making capability of plastic injection molding and the materials flexibility of powder metallurgy. The process consists of the following four steps: mixing of metal powder and binder, injection molding to shape the component, debinding to remove the binder in the component, sintering to consolidate the debound parts. In this research, the physical and mechanical properties of metal injection molded 17-4 PH stainless steel were investigated with the variation of sintering temperatures (1300 °C - 1360 °C) and atmosphere conditions (argon and vacuum conditions). The relative density, microstructure, distortion, and hardness are measured and analyzed in this study. The results show that highest relative density of 87%, relative homogeneous shrinkage and high hardness are achieved by sintering at 1360 °C for 1.5 hours and argon atmosphere. At the same sintering temperature and time, sintering in vacuum shows lower relative density (81%) than that in argon condition due to pores growth. The pore growths were not observed in the argon atmosphere. It can be concluded that sintering stages more rapidly under vacuum condition. The hardness measurements result also showed that high hardness is obtained by high density parts. The optimum average hardness obtained in this study is 239 HV. However, the hardness properties results are still lower than 280 HV according to MPIF Standard 35 for MIM parts.

Surface Capacity of Gears of Circular-Arc Tooth-Profile.(Dept.M)

The paper embodies results and analysis of an experimental investigation carried out to study the effect of case depth, case hardness and tooth load on the surface capacity or a relatively new type of gearing having teeth of circular arc profiles. These gears were manufactured from 16 MnCr5. Carburizing. quenching and tempering techniques were used with 0.5, 1.2 and 2 mm case depth and 46, 52 and 58 HRC case hardness. also applied tooth loads 5, 75 and 10 KN were used. These tiny pairs of gears were run to 6.7x107 revolutions at speed 1460rpm In a power circulating gear test rig using forced lubrication technique. Test gears were weighed at interval of times, the accumulated weight of removed metal were drawn with the number of revolutions, Wear rate was calculated and drawn with the applied tooth load, case depth and case hardness. A curve fitting was made for these experimental results using Grapher software. Results show that an optimum case depth of the case hardened gears of circular arc tooth profile equal to 1.1 m and also optimum case hardness of the case equal to 53.5 KRC. Wear rate increases with increasing the applied tooth load. Wear rate for unhardened gears increases by 4 to 192 times than that of the case hardened gears. An empirical formulae for the accumulated weight of removed metal with number of revolution, wear rate with tooth load, case depth and case hardness were derived, also presented on the curves and discussed.

Fabrication and Characterization of Dental Implants with Yttria- Stabilized Zirconia

Introduction: Zirconium oxide or zirconia have been used for the fabrication of dental implants due to their biocompatibility, hardness, toughness, compressive strength and chemical stability. The aim of this study is investigating the effect of sintering time on the properties of zirconia dental implant. Materials and Methods: In this research, which was performed at Department of Dental and Biomedical Materials Science, Nagasaki University, Nagasaki, Japan, at 2019, zirconia-yttria mol.% 3 powder was pressed and sintered at 1450°C at different times (5 samples for each condition) and the effect of time on the phase, structural and mechanical properties of the sintered samples was investigated. One-way ANOVA statistical analysis was performed with the 0.05 level of significance using Graph Pad Prism 6 software. Results: The results of XRD phase analysis show that sintering time change has a significant effect on the phase changes of the samples and the Vickers hardness of the samples shows a significant increase with increasing sintering time due to shrinkage and decrease in porosity of the samples. But the 12 hour times of sintering caused phase changes in the samples which is not desirable. Conclusion: Therefore, for the fabrication of zirconia parts with minimum porosity and optimum hardness, a moderate sintering time (6 hours) is recommended.

Optimum Processing of Absorbable Carbon Nanofiber Reinforced Mg–Zn Composites Based on Two-Level Factorial Design

To prevent a premature failure, absorbable magnesium implants must possess an adequate mechanical stability. Among many ways to improve the mechanical properties of magnesium is by particle reinforcement, such as using carbon nanofiber (CNF). This work reports an experimental design for optimum materials and processing of CNF-reinforced Mg–Zn composites based on a two-level factorial design. Four factors were analyzed: percentage of CNF, compaction pressure, sintering temperature, and sintering time, for three recorded responses: elastic modulus, hardness, and weight loss. Based on the two-level factorial design, mechanical properties and degradation resistance of the composites reach its optimum at a composition of 2 wt % CNF, 400 MPa of compaction pressure, and 500 °C of sintering temperature. The analysis of variance reveals a significant effect of all variables (p < 0.0500) except for the sintering time (p > 0.0500). The elastic modulus and hardness reach their highest values at 4685 MPa and 60 Hv, respectively. The minimum and maximum weight loss after three days of immersion in PBS are recorded at 54% and 100%, respectively. This work concludes the percentage of CNF, compaction pressure, and sintering temperature as the main factors affecting the optimum elastic modulus, hardness, and degradation resistance of CNF-reinforced Mg–Zn composites.
