Modification of Liquid Glasses Is a Key Factor in the Technology of Obtaining Hybrid Compositions and Coatings with Anticorrosive Properties

The aim of the work was to investigate the prospects of imparting valuable physical and chemical properties, such as corrosion resistance, impact and bending strength, adhesion and storage stability, to hybrid systems of potassium and sodium silicates by modification with organic compounds. Here, we present the results of worldwide activities of scientific teams studying the manufacturing technology of modified liquid glass anticorrosive coatings used in chemical, petrochemical industry and modern construction. The authors theoretically and economically justified and put into practice novel organic and inorganic compositions with increased viability. The durable and waterproof coatings with good adhesion to various substrates (non-ferrous metals, steel, plastered surface and wood) were obtained. The authors demonstrate the possibility of recycling of zinc-containing rongalite production wastes and sludge pastes of electrochemical productions containing alkali and alkaline-earth metal cations by including them into the composition instead of pigmenting solid-phase components. We propose a technological route for obtaining anticorrosion coatings to protect aluminum and its alloys operated in a zone of elevated (up to 673 K) temperatures.

Thermal Spray Coating Technology – A Review

Thermal spray coating involves heating of coating materials (ceramic, carbide, and metal alloys) to a semi-molten or molten state and propels to substrate. The flame temperature is in the range of 3,000 to 16,000OC but the surface temperature of the substrate rarely exceeds 500 OC depending on the thermal spray processes being used. The coating materials are feed into the spray gun in the form of powders, rods or wires. Thermal spray coating is use for the following purposes; (i) increase corrosion and wear resistance, (ii) protection against electromagnetic, or electrostatic, (iii) protection against radio frequency interference, (iv) metal buildup and, (iv) cosmetic. Thermal spray coating can be categorized into five most common processes; (i) Flame arc spraying, (ii) Electric Arc spraying, (iii) Plasma arc spraying, (iv) High-velocity Oxy/Fuel (HVOF) and (v) Detonation Gun. In this paper, thermal spraying processes will be explained, along with the advantages and disadvantages of one another.

Microabrasive wear behavior of different stellites obtained by laser cladding and casting processes

Cobalt superalloys are used in several applications, mainly involving corrosive environments and high temperatures, in which wear and corrosion resistance are key factors in their performance. These alloys can be produced by a variety of manufacturing processes. Among these, the technology of laser cladding coatings has emerged as a promising and economically viable alternative to produce coatings from cobalt-based alloys. One of the applications of these alloys is in the production of components to obtain second-generation ethanol. In this application, about 8% of the processed material is composed of micrometric abrasive particles, mainly silica, among others, which cause wear of components. In order to better understand the tribological behavior of these alloys in microabrasion, three coatings of commercial cobalt-based superalloys, Stellite 1, 6 and 12, were produced by laser cladding. Additionally, two cast alloys, Stellite 250 and an experimental Stellite alloy, were also evaluated. Microabrasion tests using a statistical design of experiments were performed with SiO2, Al2O3 and SiC abrasives in a suspension of distilled water. Statistical analysis revealed that the wear coefficients of these alloys are influenced by both the abrasives and the alloy. The as-cast Stellite 250 alloy showed the highest wear coefficients, while the coated Stellite 1 and the as-cast experimental Stellite showed the lowest wear coefficients. The predominant wear micromechanism was scratching, except for Stellite 6 and 12 coated alloys in SiC tests, in which predominant mechanism were mixed and rolling, respectively. The presence of secondary micromechanism of rolling wear was also observed and associated with the granulometric distribution of the abrasives. The analysis of wear severity allowed the comprehension of the granulometric distribution influence of abrasive particles on wear.

Development of Superabsorbent Polymer (SAP) Seed Coating Technology to Enhance Germination and Stand Establishment in Red Clover Cover Crop

Drought conditions after sowing threaten the seedling establishment of all seeds, including cover crops. Cover crops are commonly broadcast and, thus, are often susceptible to drought stress after sowing. Our hypothesis was that seed coating with superabsorbent polymers (SAPs) would enhance germination in the lab and stand establishment in the field by increasing water availability to single seeds. Red clover (Trifolium pratense L.) seeds were coated with the following selected SAP formulations at 2% of their seed weight: cross-linked potassium polyacrylate (PAL), cross-linked polyacrylamide-based polymer (PAM), PAM with graphite (PAM+G), and Starch-g-2-Propenoic acid (potassium salt) (STR). The water absorbency of each SAP formulation was >200 g water/g of polymer; STR had the greatest absorbency, at 352 g water/g of polymer. A seed coating method was developed, resulting in the uniform application of SAP from seed to seed. All SAP coating treatments increased germination compared to the 0% SAP coating in controlled environment studies in the lab. Three field trials were conducted for each seed coating treatment, providing a range of climatic soil conditions. Within each field trial, the STR with the greatest water absorbency had a higher stand for treatments sown by broadcasting followed by raking to incorporate seeds. The first two trials were conducted under more stressful conditions. PAM+G performed best in the first two trials by broadcasting seeds with no raking. Collectively, the selected SAP seed coating improved field stands compared to the non-treated controls.

Study the optical properties of Titanium dioxide Nano films

In this paper, Titanium Dioxide was prepared, from Titanium Isopropoxide (TIP) (C 12 H 28 O 4 Ti) with a purity of 98.1% and acetic acid (CH 3 COOH) with a purity of 99.5% and ethanol (C 2 H 5 OH) with a purity of 99.7%. all these materials are from (Aldrich Chemicals Company) by using the (Sol–gel) method, Then Tio 2 was prepared and deposited on glass slides with Spin Coating technology at three different speeds ranging from 1000 to 3000 rpm. a thin film was obtained with a certain thickness according to the speed, as the faster the speed, the less the thickness of the film and vice versa after Completing the sedimentation process, the prepared samples are inserted into a programmed electric oven, The oven starts at room temperature, then stabilizes at 550 °C, for 30 min, Because the anatase phase is formed at this temperature, and then begins to decline for every minute, until it reaches room temperature, and by making optical measurements on the prepared films and matching it with what was prepared in advance, good results were obtained.

High-Temperature Solid Particle Erosion of Aerospace Components: Its Mitigation Using Advanced Nanostructured Coating Technologies

Solid particle erosion of gas turbine blades in the aerospace sector results in increased maintenance costs, high pollution, reduced engine efficiency, etc. Gas turbines in aircraft are usually operated at high temperatures. Based on the compressor stage, the temperature varies from 100–600°C, whereas turbine blades, after combustion, experience a very high temperature between 1000–1400 °C. So, a better understanding of temperature-dependent solid particle erosion is required to develop suitable solid particle erosion-resistant coatings for gas turbine blades. In this review, a detailed overview of the effect of temperature on the solid particle erosion process and different types of erosion-resistant coatings developed over the last four decades for compressor blades are discussed in detail. In the initial sections of the paper, solid particle erosion mechanisms, erosion by different erodent media, and the influence of erosion on gas turbine engines are discussed. Then, the erosion rate trend with increasing temperature for ductile and brittle materials, high-temperature erosion tests in a corrosive environment, and the role of oxidation and bonding nature in high-temperature erosion are examined. In most cases, the erosion rate of materials decreased with increasing temperature. After this, the evolution of erosion-resistant coatings over the last four decades that are first-generation (single-phase coatings), second-generation (metal/ceramic multilayer coatings), and third-generation (nanocomposite and nano-multilayer coatings) erosion-resistant coatings are reviewed in detail. The third-generation nano coatings were found to be superior to the first- and second-generation erosion-resistant coatings. Finally, some of the commercial or notable erosion-resistant coatings developed in the last decade are discussed. The paper concluded with the research gaps that need to be addressed to develop efficient erosion-resistant coatings.

Rational fabrication of high-durability superhydrophobic coatings based on the excellent compatibility between nanoparticles and polymers

Superhydrophobic coatings arouse much attention for their extensive potential applications from industry to our daily life. The introduction of nanoparticles into polymer matrix is one of the main methods to construct superhydrophobic coatings. However, the fabrication and practical application of super-antiwetting coatings are frequently hindered, owing to the incompatibility between inorganic nanoparticles and organic polymer matrix. Herein, we develop a durable coating that tackles the compatibility problem of inorganic and organic phases, formulating with hyperbranched polysiloxane modified silica nanoparticles and silicon-based acrylic polymers. The as-prepared coatings exhibit excellent superhydrophobicity with CA beyond 158° and SA below 4°. They are capable of retaining superhydrophobicity after exposing to harsh conditions including immersion in acid-base solutions for 12 days, boiling water for 3 h and high temperature of 150 °C for 24 h, as well as experiencing various mechanical damage such as 100 cycles of sandpaper abrasion, 40 cycles of tape peeling and 200 g sand impact. Furthermore, the coating can be further applied to anti-insect blood adhesion under dynamic conditions, self-cleaning of pollutants in life and substrate surfaces with diverse properties. The preparation technology of superhydrophobic coatings has unique advantages in scalable productivity, less equipment requirements and mild process conditions, and also provides insights into the fabrication of superhydrophobic coatings with good compatibility of inorganic and organic materials.

Preparation of textured epoxy resin coatings for excellent hydrophobicity and corrosion resistance

Because of the severe corrosion of marine structural steel under the splash zone, it is proposed to prepare surface textures in widely used epoxy resin (ER) coatings to improve the hydrophobicity and corrosion resistance. However, the surface texture preparation technology of organic coatings is flawed and needs to be improved. Template method, one of the textured preparation technologies of organic coatings, has the trouble that the air bubbles, which diminish the coating quality. In this paper, the method of curing at room temperature and vacuum treatment is used to reduce the generation of air bubbles. Scanning electron microscope (SEM) images show the complete morphology and texture dimensions of the textured ER coatings. The hydrophobic properties of the textured ER coatings were systematically investigated, the contact angles of the textured ER coatings were significantly improved, and all the textured ER coatings samples met the hydrophobic criteria. And the wetting state model of the textured ER coatings was determined by modifying the Wenzel wetting mode. Furthermore, the electrochemical impedance spectroscopy (EIS) analysis of the textured ER coatings shows that the corrosion resistance is improved by two orders of magnitude compared to the smooth ER coatings. That shows excellent corrosion resistance, and the effect of the texture parameters on the corrosion resistance and hydrophobic properties of the textured ER coatings showed a high degree of consistency. The preparation technology of surface textured coatings has great potential in the preparation and application of marine anti-corrosion organic coatings.

Anti-Corrosion Reinforcements Using Coating Technologies-A Review.

Coated reinforcements are expected to improve the performance of reinforced concrete in aggressive environments, but different kinds of coated reinforcements can express a variety of properties, which can confuse researchers and engineers. This paper reviews the manufacture, corrosion mechanisms, behaviors, and applications of popular or promising coated reinforcements, incorporating galvanized reinforcements (GRs), epoxy coated reinforcements (ECRs), stainless cladding reinforcements (SCRs), and steel-fiber reinforced polymer composite bars (SFCBs). In terms of manufacture, GRs and ECRs should focus on minimizing the negative effect of manufacture on performance, while SCRs and SFCBs should reduce the cost and increase the production capacity. Behaviors of GRs and ECRs are primarily determined by the steel substrate, but the behaviors of SCRs and SFCBs are primarily affected by the coat and core, and their interaction. The corrosion mechanism of GRs and SCRs is about oxidation, while that of SFCBs is about hydrolysis. ECRs are usually corroded under film, which can be a cause of premature failure. Corrosion embrittles SCRs, as well as bare bars, but corrosion of SFCBs usually causes a reduction in maximum strength. The investigation of the corrosion behaviors of GRs and ECRs focuses on bond strength. GRs have controversial performance. ECRs have been proven to have drawbacks regarding bond strength. The use of anti-corrosion reinforcement is uneven in regions, which may correlate with the development of technology and the economy.

Biochar Coating Is a Sustainable and Economical Approach to Promote Seed Coating Technology, Seed Germination, Plant Performance, and Soil Health.

Seed germination and stand establishment are the first steps of crop growth and development. However, low seed vigor, improper seedbed preparation, unfavorable climate, and the occurrence of pests and diseases reduces the germination rate and seedling quality, resulting in insufficient crop populations and undesirable plant growth. Seed coating is an effective method that is being developed and applied in modern agriculture. It has many functions, such as improving seed vigor, promoting seedling growth, and reducing the occurrence of pests and diseases. Yet, during seed coating procedures, several factors, such as difficulty in biodegradation of coating materials and hindrance in the application of chemical ingredients to seeds, force us to explore reliable and efficient coating formulations. Biochar, as a novel material, may be expected to enhance seed germination and seedling establishment, simultaneously ensuring agricultural sustainability, environment, and food safety. Recently, biochar-based seed coating has gained much interest due to biochar possessing high porosity and water holding capacity, as well as wealthy nutrients, and has been proven to be a beneficial agent in seed coating formulations. This review presents an extensive overview on the history, methods, and coating agents of seed coating. Additionally, biochar, as a promising seed coating agent, is also synthesized on its physico-chemical properties. Combining seed coating with biochar, we discussed in detail the agricultural applications of biochar-based seed coating, such as the promotion of seed germination and stand establishment, the improvement of plant growth and nutrition, suitable carriers for microbial inoculants, and increase in herbicide selectivity. Therefore, this paper could be a good source of information on the current advance and future perspectives of biochar-based seed coating for modern agriculture.

Aluminum Electrodeposition on the Surface of Boron Carbide Ceramics by Use EMIC–AlCl3 Ions Liquid

Coating technology is decisively important for metallization of ceramic materials and ceramic metal sealing technology. Previous studies have shown that the network-like structure after penetration of molten aluminum can significantly improve the strength of joint components. However, the direct aluminum coating method is limited by the shape of the substrate. To obtain a dense aluminum film on the surface of B4C, in this study, aluminum was deposited by pulse electroplating in EMIC–AlCl3 ionic liquid. The deposited metals were observed and analyzed by SEM–EDS and XRD. A Vickers hardness tester was adopted as an auxiliary equipment to clarify the film quality. The results show that frequency and duty cycle have significant effects on crystal orientation. The content of oxides in the contact gap reduces the bonding strength of the deposited metal, which provides experimental basis for metal electrodeposition on B4C.

The Adhesion of Protective Coatings to Novel Trivalent Cr Metal / Cr Oxide Coatings Used for Packaging Applications

When manufacturing canned goods, the aim is to create a shelf-stable product that will keep for anywhere between one and five years (under ambient storage conditions). It is for this reason that steel, which offers desirable mechanical properties, is often used. However, steel is known to undergo corrosion thus impacting final product quality. It is therefore common for packaging substrate materials to have a protective metallic coating which is further coated with a lacquer to shield both the substrate material from the cans contents and vice-versa.One example of a coated packaging product is Electrolytic Chromium Coated Steel (ECCS) which is typically used for lacquered applications [1]. This chrome coating is deposited from a chromic acid bath containing Cr (VI) and results in a steel substrate covered in a bi-layer chromium metal (~20 nm) /chromium (hydr)oxide (~7 nm) layer. This substrate is then overcoated with lacquer which is usually epoxy based.Once the can is lacquered and filled, a retort process is used to pressure cook its contents. This is undertaken at 121 °C at a pressure of 1 bar for 90 minutes. This retort process has proven to be detrimental to the adhesion of protective lacquers applied to the substrate material which serve to prevent corrosion caused by the cans contents [2,3]. At elevated temperatures and pressures, the lacquers exhibit porosity which creates an ion pathway for the cans chemical contents to migrate through the coating and interact with the substrate. This interaction initiates localised corrosion on the surface causing de-adhesion of the lacquers through localised anodic metal dissolution.However, both Cr (VI) and Bisphenol-A, a chemical commonly added to epoxy lacquers to enhance thermal and chemical stability, have been identified as substances of concern by REACH - a regulation associated with the restriction of chemicals that are harmful to human health. Thus, a dual issue exists of finding a suitable substrate replacement for ECCS and investigating the adhesion of lacquers to this substrate. Coatings made with Trivalent Chromium Coating Technology (TCCT®) are currently being developed as a potential replacement for ECCS. TCCT® production has developed to consist of a two-electrolyte process. Various issues including coating in-homogeneity have previously been reported [4]. Additionally, lacquers to which Bisphenol-A have not intentionally been added (BPANI) have been manufactured.To ensure that TCCT® substrates are successful, it is important that they perform comparably to existing products such as ECCS. For this reason, a range of TCCT® substrates varying in Cr (III) oxide coating weight (1.8 mg.m-2 to 23.35 mg.m2) have been experimentally analysed for their lacquer adhesion (both epoxy-phenolic and BPANI) in simulated industrial retort conditions, using scratch testing. They have also been analysed for their surface electrochemical activity utilising the scanning vibrating electrode technique (SVET) which is a technique designed to spatially resolve areas of dissimilar electrochemical activity.A Cr (III) oxide coating weight of approximately 8-10 mg.m2 was found to be critical to the adhesion of the lacquers. In addition, the SVET scans illustrated a pronounced rate of increase in anodic activity on the substrates coated with smaller amounts of Cr (III) oxide. Indeed, higher coating weights exhibited a lower total anodic and cathodic activity alluding to the insulating and inert nature of Cr (III) oxide.[1] B.

Electrodeposition of Molybdenum from Water-in-Salt Electrolytes

Molybdenum is attractive to the manufacturing industry due to its high melting point and extremely low thermal expansion. Generally, Mo can be produced by thermal spraying, sintering, and pressing at high temperatures. Electrodeposition has been used widely as low-temperature method to prepare metals and alloys as coatings or films. However, it is well-known that metallic molybdenum is difficult to deposit from aqueous solution due to its highly negative reversible potential. More recently, a few studies have successfully deposited metallic molybdenum from highly concentrated acetate solutions1,2 as a thick coating on metallic objects. In this work, we report a systematic study on Mo deposition using this electrolyte system under the umbrella of water-in-salt concept. Aqueous electrolytes with an extremely high concentration of salt, known as water-in-salt electrolytes, offer a special electrolyte environment for electrodeposition where free water molecules are reduced by the hydration of salt.This report focuses on the effects of substrate and electrolyte chemistry on the Mo deposition process as well as the film properties. In this study, Cu electrode is fabricated by depositing Cu layer on Pt electrode. The electrochemical behavior is studied using cyclic voltammetry on Pt and Cu disc electrodes, as shown in Figure 1. Mo deposition starts at about -2.0 V on both Pt and Cu. In the anodic scan, the deposited Mo film begins to dissolve at -0.7V. X-ray fluorescence is used to measure film thickness, which is consistent with the stripping charge according to Faraday’s laws. However, the amount of Mo deposited on Cu, represented by the anodic stripping charge excluding the charge for Cu stripping, is much higher than that on Pt electrode. On the other hand, the presence of CH3COOK is found extremely critical for Mo deposition despite of a high total concentration of acetate. It is believed to relate to a suppressed proton reduction in presence of alkaline metal cations in a super highly concentrated acetate electrolyte. This correlation between hydrogen evolution reaction and Mo deposition is also consistent with the promoted deposition rate on Cu than on Pt surface. DC deposition studies are carried out to further verify these observations and to allow characterization of deposited Mo. Details will be further discussed in the poster presentation.1 Morley, T. J. et al., "The deposition of smooth metallic molybdenum from aqueous electrolytes containing molybdate ions," Electrochemistry Communications 15, 78-80 (2012).2 Syed, R. et al., "Electrodeposition of thick metallic amorphous molybdenum coating from aqueous electrolyte," Surface & Coatings Technology 261, 15-20 (2015).

(Digital Presentation) Fundamental Insights into Electrodeposition of Mixed Chromium Metal-Carbide-Oxides from Trivalent Chromium – Formate Electrolytes

Recent restrictions on industrial usage of hexavalent chromium under new REACH legislation have further sparked the development of hexavalent chromium-free chromium plating processes. An industrially important development in this field is Trivalent Chromium Coating Technology (TCCT®), a chromium electroplating technology for packaging steel developed at Tata Steel. In this process, aqueous trivalent chromium electrolytes rather than hexavalent chromium electrolytes are employed for the electrodeposition of metallic chromium. However, to deposit metallic chromium from a trivalent chromium electrolyte, it is necessary to incorporate a complexing agent given the kinetic inertness of aqueous trivalent chromium complexes. Formate plays this role in the TCCT® process yielding coatings comparable to the conventional hexavalent chromium-based process [1-4].However, understanding the mechanism and kinetics of chromium electrodeposition from this system is quite limited. Fundamental knowledge of the deposition process is key for industrial process optimization. Essential to determining the reaction mechanism and kinetics is the identification of the chemical species involved in the reaction. Using a hybrid multiscale experimental and computational approach, insights into chromium complexation in the bulk electrolytes and how this speciation influences the composition of the deposit have been gained.Samples electroplated in electrolytes of varied formate concentrations were characterized using X-ray Fluorescence (XRF) spectroscopy and X-ray Photoelectron Spectroscopy (XPS). Results from these analyses show that metallic chromium is only deposited when the electrolyte contains formate ions. In the absence of formate, only oxide and carbide species are deposited. The characterization results also show a current efficiency of the TCCT process of ~ 40%. From observations from surface characterization as well as spectroscopic analysis and density functional theory (DFT) and ab initio molecular dynamics studies (AIMD) of the bulk electrolyte, the coordination and complexation of formate ion in the chromium complex responsible for metallic chromium deposition have also been identified. Voltammetric studies coupled with ex-situ XPS and scanning electron microscopy (SEM) surface characterization also lead to a clear definition of the reaction mechanism of metallic chromium deposition that the incorporation of formate in trivalent chromium electrolytes makes possible.

Preparation and Tribological Properties of Graphene-Based Coatings on Tungsten Carbide

The preparation technology of graphene-based coatings on cobalt-based cemented carbides and the friction properties of graphene-based coatings were researched. Based on cooling rate, growth temperature, and methane flow rate, Raman spectroscopy was used to evaluate the influence of chemical vapor deposition (CVD) on graphene-based coatings. The results show that at the growth temperature of 1000 °C, the cooling rate of 15 °C/min and methane flow rate of 10 sccm are more favorable for the growth of pure graphene coating with fewer layers on a cemented carbide surface. As methane flow boosts, the number of graphene layers increases and amorphous carbon is generated. The resulting tribological properties demonstrate that the friction coefficient of graphene-based coatings decreases as the friction load increases. The above results indicate that the graphene-based coating on a cemented carbide surface can be prepared by regulating its composition and defects through technological parameters, and it is viable to use graphene-based coating as anti-wear coating for cutting tools. The results provide a reference for the preparation and properties of cemented carbide surface graphene.
