Enhanced magnetic properties and anisotropy in hot-deformed Ce–Fe–B magnets by suppressing CeFe2 phase with Ga addition

Nanocrystalline Ce–Fe–B alloys exhibit potential utilization for low-cost permanent magnets, however, the preparation of anisotropic magnets with satisfactory magnetic properties remains a challenge. CeFe2 Laves phase with high melting point that forms in the Ce-rich Ce–Fe–B magnets has been considered as the reason to be detrimental to its hot-working process and magnetic performance. Herein, we report the significant effects of adding Ga to nanocrystalline melt-spun Ce17Fe78-xB6Gax alloys on suppressing the CeFe2 phase and enhancing coercivity. The x = 2.0 alloy is identified as the optimal precursor for preparing anisotropic hot-deformed magnet due to its lower CeFe2 phase content (5.7 wt.%), considerably less than that of the ternary Ce–Fe–B alloy (17.6 wt.%). The congruent alignment and platelet-shaped grain characteristics are obtained in the Ga-added hot-deformed magnet, indicating an enhanced anisotropy that results in an improved remanence from 4.2 kGs to 5.9 kGs. The development of such texture can be ascribed to the reduced amount of CeFe2 phase, allowing the formation of Ce-rich grain boundary (GB) phase, which is necessary to induce grain alignment during hot deformation process. Two types of Ga-containing GB phases are found in the Ga-added magnet, namely typical Ce-rich/Fe-lean GB phase and Ce6Fe13Ga phase. The uniformly distributed Ce-rich GB phases surrounding the main grains helps to magnetic isolate the Ce2Fe14B grains and thus enhance the coercivity, as verified by detailed microstructural characterizations combined with micromagnetic simulation. The work offers a potential way to realize anisotropy in Ce–Fe–B magnets and inspires further exploration of high abundance Ce-based magnets.

Mirrored symbols, opposite effects: Impact of Ga and Ag additions on the martensite decomposition of the Cu81Al19 alloy

Although the presence of martensite is desirable in several applications of increasingly complex Cu-rich Cu-Al alloys, there is a lack of understanding about the effects of alloying in its stability. Martensite decomposition was investigated in as-quenched Cu81Al19, Cu79Al19Ga2, and Cu79Al19Ag2 alloys (compositions in atomic percentage) by optical microscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, differential scanning calorimetry, and Vickers microhardness measurements. It was found that the similarity of crystalline structure between alloying element and host phase, as well as the interactions between ternary addition atoms and Al interfere with the stages of the martensite decomposition during heating. The Ga addition refined the microstructure, resulted in the precipitation of other phases, and favored the eutectoid reaction in the Cu81Al19 alloy. The Ag addition increased the tendency for martensite ordering, stabilized the β1 phase, and induced the precipitation of Ag particles from martensite on heating. Possible technological consequences arising from these results were also discussed.

Synergistic enhancement of modified sericite on rheological and foaming properties of poly (lactic acid)

Due to low melt strength and slow crystallization rate, poly (lactic acid) (PLA) foam materials are still not satisfactory. In order to improve the foaming performance of PLA, sericite (GA) was selected as the filler and modified by 3-Aminopropyltriethoxysilane (KH-550). Through melt blending with PLA, azodicarbonamide (ADC) foaming agent was selected for molding foaming, and PLA/GA composite foam was prepared. The addition of GA not only acts as a nucleating agent to improve the crystallization performance of the blend, but also improves its complex viscosity and storage modulus, and enhances its melt strength, so that the compressive strength and impact strength of the prepared composite foam are increased by 265.5 % and 224.0 %, respectively. Compared with PE foam, PLA/GA composite foam showed excellent thermal insulation performance through thermal infrared imaging test. Based on its mechanical and thermal insulation properties, this sample provides new materials for the field of wall insulation and foam packaging. This study provides an effective way to improve the melt strength and workability of PLA.

Gallium bioionflotation using rhamnolipid: Influence of frother addition and foam properties

The current study investigated the application of rhamnolipid biosurfactant as an ion collector in bioionflotation. In a top-down approach, the influence of rhamnolipid on gallium (Ga) ion flotation and recovery were investigated followed by detailed studies on the influencing parameters and foam characterization. Rhamnolipid exhibits extensive foaming properties and foam produced by rhamnolipid alone has higher stability making it difficult to collect the flotation concentrates. An addition of 1,2-decanediol introduces instability to this foam and also aids in concentrate collection. Observations during the flotation studies resulted in a series of investigations on rhamnolipid properties such as aggregate size, surface tension, and foam characterization. These results indicated that the addition of Ga and/or 1,2-decanediol affected the molecular aggregation of rhamnolipid. Moreover, the surface activity, foamability, foam drainage, and foam coarsening/coalescence of the rhamnolipid changed in the presence of Ga and/or 1,2-decanediol. In a batch bioionflotation process, rhamnolipid was able to remove nearly 80% Ga at pH 7 in presence of 1,2-decanediol. However, upgrading was higher at pH 6 without 1,2-decanediol, which is important when considering the flotation recovery in presence of other metals. Such biosurfactants have a high potential for wide applications in ion flotation and further optimization of flotation parameters is essential.

Microstructure and mechanical properties of Sn-xGa alloys and solder joints

Though Ga is a promising addition used in third-generation lead-free solders for harsh-environment applications, its influences on βSn structure and mechanical properties of solder alloys/joints are still unknown. This study demonstrated that Ga additions in Sn-XGa (X = 0.5, 1.0, 2.0 in wt%) can moderately refine βSn grains but render the alloys more susceptible to recrystallization during cross-section and polishing. Sn-1.0Ga shows substantially elevated yield/tensile strengths (45.1 MPa/64.9 MPa) compared with pure Sn, attributed to the strong solid-solution strengthening effect of Ga, and it also possesses good tensile ductility of >25%. Compared with pure Sn and Sn-3.0Ag-0.5Cu (SAC305) solder joints on Cu, Sn-XGa/Cu solder joints show significantly reduced dissolution of Cu substrate that benefits in suppressing the formation of primary Cu6Sn5. Among Sn-XGa/Cu, Sn-2.0Ga/Cu joint exhibits high shear strength (69.4 MPa) comparable to that of SAC305/Cu joint (70.5 MPa), owing to the Ga solid-solution strengthening and the extra second-phase strengthening from Cu9Ga4.

Effect of minor gallium addition on corrosion, passivity, and antibacterial behaviour of novel β-type Ti–Nb alloys

Metastable Ti–Nb alloys are promising bone-implant materials due to improved mechanical biofunctionality and biocompatibility. To overcome increasing bacterial infection risk, alloying with antibacterial elements is a promising strategy. This study investigates the effect of minor gallium (Ga) additions (4, 8 wt% Ga) to as-cast and solution-treated β-type Ti–45Nb-based alloy (96(Ti–45Nb)-4Ga, 92(Ti–45Nb)-8Ga (wt.%)) on corrosion and passive film properties, as well as cytocompatibility and antibacterial activity. The electrochemical properties were evaluated by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and Mott-Schottky analyses in phosphate-buffered saline (PBS). X-ray photoelectron spectroscopy (XPS) was performed to analyze the chemical composition of passive films. Early adhesion and viability of macrophages and Staphylococcus aureus were assessed by nucleocounting and colony-forming unit counting, respectively. The results showed that high corrosion resistance and passive film properties of Ti–45Nb are retained and even slightly improved with Ga. EIS results revealed that Ga addition improves the passive film resistance. XPS measurements of 92(Ti–45Nb)-8Ga show that the passive film contains Ti-, Nb- and Ga-based oxides, implying the formation of mixed (Ti–Nb-Ga) oxides. In addition, marginal Ga ion release rate was detected under free corrosion conditions. Therefore, it can be assumed that Ga species may contribute to passive film formation on Ga-containing alloys. The 92(Ti–45Nb)-8Ga elicited an antibacterial effect against S. aureus compared to cp-Ti at 4 h. Moreover, Ga-containing alloys showed good cytocompatibility with THP-1 macrophages at 24 h. In conclusion, it was demonstrated that Ga additions to Ti–45Nb are beneficial to corrosion resistance and showed promising initial host and bacterial interactions.

Effects of Co-Addition of Guanidinium and Cesium to CH3NH3PbI3 Perovskite Solar Cells

The effects of guanidinium (C(NH2)3, GA) and cesium (Cs) co-additions on methylammonium lead iodide (CH3NH3PbI3, MAPbI3) perovskite solar cells were investigated. The first-principles calculations on the density of the states and band structures showed a reduction in the total energy by the GA addition. Although the calculation showed that the co-addition of the GA/Cs to the MAPbI3 perovskite could decrease the carrier mobilities, and the addition of GA/Cs improved the device performance. This result would be due to a facilitation of grain growth and a suppression of the defects from the GA/Cs addition. The changes to the conversion efficiencies of the device with the best performance were small, which indicates that the present co-addition of GA/Cs is effective for the stability of the devices.

Microstructure and properties of a novel Cu20Ni 20Mn-xGa alloy with high strength, high elasticity and high plasticity

The Cu20Ni20Mn alloy possesses both high strength and excellent elastic modulus, which has the potential to work in some extreme environments. In our study, by adding Ga into the Cu-Ni-Mn alloy, a new kind of Cu20Ni20Mn-xGa (x = 0, 1, 5 wt%) alloys were produced. After undergoing different thermal-mechanical treatments, these alloys were comprehensively investigated particularly for their mechanical properties and microstructures. While at the peak aging condition, the ultimate tensile strength and total elongation of the Cu20Ni20Mn-1Ga alloy are 1476 MPa and 7.9% respectively, both are higher than that of the Ga-free case (1391 MPa and 3.9%). The Ga added in small amount facilitates the nucleation of NiMn nanoprecipitates inside the grain instead of on the grain boundary, which provides enormous precipitation strengthening and greatly enhances the alloy. However, with addition of excessive Ga (e. g. 5 wt%), discontinuous Ni2MnGa precipitates are observed at grain boundaries, which greatly reduce the ductility of the alloy. Based on our research, we believe that adding appropriate amount of Ga is beneficial for the mechanical properties of the Cu-Ni-Mn alloys, which will become a potential strengthening method for Cu alloys in the future.

Reactive single-step hot-pressing and magnetocaloric performance of polycrystalline Fe2Al1.15−xB2GexGax (x = 0, 0.05) MAB phases

Reactive single-step hot-pressing at 1473 K and 35 MPa for 4 h produces dense, bulk, near single-phase, low-cost, and low-criticality Fe2Al1.15B2 and Fe2Al1.1B2Ge0.05Ga0.05 MAB samples, showing second-order magnetic phase transition with favorable magnetocaloric properties around room temperature. The magnetic as well as the magnetocaloric properties can be tailored upon Ge and Ga doping, leading to an increase in the Curie temperature TC and the spontaneous magnetization mS. The maximum isothermal entropy change ΔsT,max of hot-pressed Fe2Al1.15B2 in magnetic field changes of 2 and 5 T amounts to 2.5 and 5 J(kgK)−1 at 287.5 K and increases by Ge and Ga addition to 3.1 and 6.2 J(kgK)−1 at 306.5 K, respectively. The directly measured maximum adiabatic temperature change ΔTad,max is improved by composition modification from 0.9 to 1.1 K in magnetic field changes of 1.93 T. Overall, we demonstrate that hot-pressing provides a much faster, more scalable, and processing costs reducing alternative compared to conventional synthesis routes to produce heat exchangers for magnetic cooling devices. Therefore, our criticality assessment shows that hot-pressed Fe-based MAB phases provide a promising compromise of material and processing costs, criticality, and magnetocaloric performance, demonstrating the potential for low-cost and low-criticality magnetocaloric applications around room temperature.

Using concentration gradients to examine the effects of Al, Ga and Sn additions on the low-activation VCrMnFe system

A critical design criterion for future fusion reactor components is low activation. The equiatomic multi-principal element alloy VCrMnFe is comprised solely of low activation elements and forms a single-phase solid solution at temperatures over 1000 °C. However, at lower temperatures it forms detrimental sigma phase. In this work, compositional gradients of Ga, Sn or Al were induced in VCrMnFe using only a furnace to investigate their effect on intermetallic formation. By examining how the microstructure changed across a region with varying composition, phase stability limits could be assessed. For example, all three elements were found to prevent sigma phase from forming within the alloy when they were present at relatively low concentrations (2–5 at%). Al was found to be the most promising addition (in terms of not causing embrittlement), and the approach used enabled the characterisation of the VCrMnFe–Al pseudo binary phase diagram up to 50 at% Al after heat treatment of 800 °C/240 h followed by ageing at 600 °C/240 h, with numerous ordered phases found using electron diffraction. The level of Al addition required to suppress the sigma phase has been identified more precisely, which will be useful for future alloy development work.

Effects of Indium and Gallium ratio on tarnish resistance, corrosion and mechanical properties of 950 silver alloy

The effects of Indium (In) and Gallium (Ga) ratio on tarnish resistance, corrosion and mechanical properties of 950 silver alloy were studied. 950 Silver alloy with aluminium (Al), silica (Si) and germanium (Ge) were added with In and Ga at the range of 0.44 to 1.90 weight percent. The increment of secondary structure with Ge-Si rich phase in Ag-Al alloy increases hardness, but reduces ultimate tensile strength. The addition of In and Ga improves tarnish and corrosion resistance. The color differences as indicated by Delta E tolerances (DE*) of Ag-Al alloys are in the range of 8.64 to 11.40 while this property of Ag-Cu is 39.37. Ecorr of Ag-Al alloys are in the range of -0.068 to -0.010 V which are higher than that of Ag-Cu Alloy (-0.147 V). Besides, Ga is more effective for tarnish and corrosion resistance than In. However, Ga/In co-addition reduces these properties by the formation of Ge-Si-Ga-In phase. The protective thin film of Ag-Al alloy was detected by XPS. The Al2O3, In2O3 and Ga2O3 films were found. When the proportion of Ga in Ag-Al alloys increases, the hardness marginally increases while the tensile strength slightly reduces. The additions of Al, Ga, In, Ge and Si reduce the melting point of Ag-Al alloys comparing with Ag-Cu alloy and simultaneously improve the casting quality.

Alloying as a Strategy to Boost the Stability of Copper Nanocatalysts during the Electrochemical CO2 Reduction Reaction.

Copper nanocatalysts are among the most promising candidates to drive the electrochemical CO2 reduction reaction (CO2RR). However, the stability of such catalysts during operation is sub-optimal, and improving this aspect of catalyst behavior remains a challenge. Here, we synthesize well-defined and tunable CuGa nanoparticles (NPs) and demonstrate that alloying Cu with Ga considerably improves the stability of the nanocatalysts. In particular, we discover that CuGa NPs containing 17 at. % Ga preserve most of their CO2RR activity for at least 20 h while Cu NPs of the same size reconstruct and lose their CO2RR activity within 2 h. Various characterization techniques, including X-ray photoelectron spectroscopy and operando X-ray absorption spectroscopy, suggest that the addition of Ga suppresses Cu oxidation at open-circuit potential (ocp) and induces significant electronic interactions between Ga and Cu. Thus, we explain the observed stabilization of the Cu by Ga as a result of the higher oxophilicity and lower electronegativity of Ga, which reduce the propensity of Cu to oxidize at ocp and enhance the bond strength in the alloyed nanocatalysts. In addition to addressing one of the major challenges in CO2RR, this study proposes a strategy to generate NPs that are stable under a reducing reaction environment.

High energy efficiency and high discharge voltage of 2N-purity Al-based anodes for Al-air battery by simultaneous addition of Mn, Zn and Ga

As the anode material of Al air battery, 2N-purity (99 wt%) Al-based alloy has the disadvantages of low efficiency and low discharge voltage, which is attributed to the impurity of Fe in the 2N Al alloy. In this paper, the 2N Al-based anode with high energy efficiency and discharge voltage is successfully designed by adding Mn, Zn and Ga. The results show that adding Mn separately can inhibit hydrogen evolution corrosion but lead to the exfoliation corrosion of 2N Al. The addition of Ga, Mn and Zn together can suppress hydrogen evolution, decrease the weight loss of 2N Al alloy and significantly increase the output voltage and energy efficiency of an Al-air battery, which makes it possible to use cheap 2N Al as the anode of an Al-air battery.

Effects of Ga on the structural, mechanical and electronic properties of β-Ti-45Nb alloy by experiments and ab initio calculations

This work aims to investigate the structural, mechanical and electronic properties of four novel β-type (100-x)(Ti–45Nb)-xGa alloys (x = 2, 4, 6, 8 wt%) for implant applications by means of experimental and theoretical (ab initio) methods. All alloys retain the bcc β phase in the solution-treated and quenched state while the lattice parameter decreases with increase in Ga content. This is due to its smaller atomic radius compared to Ti and Nb, in line with the present density functional theory (DFT) calculations. Tensile and microhardness tests indicate a clear strengthening effect with increasing Ga content, with yield strengths in the range 551 ÷ 681 MPa and microhardness in the range 174 ÷ 232 HV0.1, mainly attributed to grain refinement and solid solution strengthening. Ga also positively affects ductility, with a maximum value of tensile strain at fracture of 32%. Non-destructive ultrasonic measurements and DFT calculations reveal that the bulk modulus is unaffected by the Ga presence. This phenomenon might be due to the fact that Ga introduced bonding and anti-bonding electron low energy states which balance the average bond strength among the atoms in the metallic matrix. Nevertheless, the introduction of new Ga–Ti super sp-like bonding orbitals along the [110] and [−110] directions in the Ga neighborhood could explain the increase of the Young's modulus upon Ga addition (73 ÷ 82.5 GPa) that was found experimentally in the present work. Hence, Ga addition to Ti–45Nb leads to a suitable balance between increased strength and low Young's modulus.

Tribocorrosion behavior of β-type Ti-Nb-Ga alloys in a physiological solution

Tribo-electrochemical behavior in physiological solution of two β-type (100-x)(Ti-45Nb)-xGa (x = 4, 8 wt%) alloys, alongside β-Ti-45Nb and medical grade Ti-6Al-4V ELI, was investigated. Microstructure and mechanical behavior were evaluated by X-ray diffraction, microhardness and ultrasonic method. Tribocorrosion tests (open circuit potential, anodic potentiostatic tests) were performed using a reciprocating pin-on-disk tribometer under constant load. Degradation mechanisms are similar for the alloys: plastic deformation, delamination, abrasive and adhesive wear. Among the β-Ti-Nb alloys, an improved wear resistance with lower damage was remarked for β-92(Ti-45Nb)-8Ga alloy, attributed to increased microhardness. Content of Ga3+ ions released in the test solutions were found to be in very low amounts (few ppb). Addition of Ga to Ti-45Nb resulted in improved corrosion resistance under mechanical loading.

Microstructure and brazing properties of a novel Ag–Cu-Ga solder

In this study, a novel low-silver Ag-xCu-5Ga (x = 28, 34, 39, 49 and 55) solder with high strength was designed and prepared. The effect of element composition on microstructure evolution, thermal behavior, and the mechanical performance of Ag–Cu-Ga solders were investigated in detail. The results indicated that the melting temperature of Ag–Cu alloy could be reduced effectively with Ga addition, and the typical joint consisted of the block-shaped Cu-rich phase in the welded seam and the ribbon-shaped Cu-rich phase adjacent to the interface. The shear strength of joints brazed with Ag-xCu-5Ga (x = 28, 34, 39 and 49) filler metals can be improved significantly compared to that of commercial Ag–28Cu solder, with a maximum value of approximately 445 MPa in Ag–39Cu–5Ga solder. The best mechanical properties are obtained as the second-phase strengthening and interfacial strengthening reach a balanced coexistence state, determined by the block-shaped Cu-rich phase in the welded seam and the ribbon-shaped Cu-rich phase adjacent to the interface, respectively. This study can provide insights to investigate strengthening mechanisms and develop high-strength solders for vacuum brazing.

Gallium-Doped Hydroxyapatite Shows Antibacterial Activity against Pseudomonas aeruginosa without Affecting Cell Metabolic Activity

Calcium phosphates (CaPs) have been used in bone regeneration for decades. Among the described CaPs, synthetic hydroxyapatite (HAp) has a chemical composition similar to that of natural bone. Gallium-containing compounds have been studied since the 1970s for the treatment of autoimmune diseases and have shown beneficial properties, such as antibacterial activity and inhibition of osteoclast activity. In this study, we synthesized hydroxyapatite (HAp) powder with Ga doping ratios up to 6.9 ± 0.5 wt% using the wet chemical precipitation method. The obtained products were characterized using XRD, BET, FTIR, and ICP-MS. Ga3+ ion release was determined in the cell culture media for up to 30 days. Antibacterial activity was assessed against five bacterial species: Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pyogenes. The biocompatibility of the GaHAp samples was determined in human fibroblasts (hTERT-BJ1) through direct and indirect tests. The structure of the synthesized products was characteristic of HAp, as revealed with XRD and FTIR, although the addition of Ga caused a decrease in the crystallite size. Ga3+ was released from GaHAp paste in a steady manner, with approximately 40% being released within 21 days. GaHAp with the highest gallium contents, 5.5 ± 0.1 wt% and 6.9 ± 0.5 wt%, inhibited the growth of all five bacterial species, with the greatest activity being against Pseudomonas aeruginosa. Biocompatibility assays showed maintained cell viability (~80%) after seven days of indirect exposure to GaHAp. However, when GaHAp with Ga content above 3.3 ± 0.4 wt% was directly applied on the cells, a decrease in metabolic activity was observed on the seventh day. Overall, these results show that GaHAp with Ga content below 3.3 ± 0.4 wt% has attractive antimicrobial properties, without affecting the cell metabolic activity, creating a material that could be used for bone regeneration and prevention of infection.

Effect of Gum Arabic (Acacia senegal and Acacia seyal) addition on antioxidant properties and oxidative stability of roselle juice

Gum Arabic (GA) is the dried exudate obtained from the tree of Acacia senegal and Acacia seyal that possess a prebiotic effect on humans. Meanwhile, roselle is a popular juice that is rich in antioxidants. However, as a complex polysaccharide, the addition of GA in roselle juice may affect the antioxidant properties of the final product. Therefore, this study aimed to determine the effect of different types of GA (Acacia senegal or Acacia seyal) addition, at different concentrations (0%, 2%, 4% and 6%) on the antioxidant properties and antioxidant stability of roselle juice during storage. The most accepted formulation of juice for each GA type along with the control sample (0% GA) was analysed for their oxidative stability during five weeks of chill storage (4±1oC). Results showed that the addition of GA increased or at least maintained the vitamin C and total phenolic content (TPC) in the range of 11.35±1.26-25.18±1.70 mg/100 mL and 21.04±1.55-45.08±4.76 mg GAE/100 mL, respectively. Nevertheless, the addition of more than 2% of GA significantly reduced (p<0.05) about 7% to 25% of total anthocyanin content. Variation of results was shown by ferric reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl free radical-scavenging activity (DPPH) assay. For storage study, all juices (0% GA, 4% A. senegal and 2% A. seyal) exhibited fluctuation in trend for all the antioxidant properties except for TPC which remained stable. In conclusion, overall findings showed the addition of GA may increase or at least maintain the antioxidant properties of the juices except for anthocyanin content and antioxidant activity (DPPH assay). Meanwhile, the addition of GA had a variation that resulted in the oxidative stability of juices during storage

Modification of structural, mechanical, corrosion and biocompatibility properties of Ti40Zr10Cu36Pd14 metallic glass by minor Ga and Sn additions

Ti40Zr10Cu32Pd14Ga4 and Ti40Zr10Cu32Pd14Sn4 (in at%) bulk metallic glasses (BMGs) with different geometries (wedges, rods, ribbons and discs) were prepared by suction casting, melt spinning and splat quenching, respectively. For comparison, the reference Ti40Zr10Cu36Pd14 BMG was cast as a rod with 2 mm diameter and in wedge-shaped form. High-energy X-ray diffraction measurements yielded a critical casting thickness of 2.4, 2.1 and at least 4 mm for the reference, Ga-containing, and Sn-containing BMGs, respectively. The extension of the supercooled liquid region of about 50 K, measured for the glassy rods and ribbons by differential scanning calorimetry, is larger than that of only 20 K found for the splat-quenched discs. As to the alloys’ mechanical properties, the Ti40Zr10Cu36Pd14 glassy rods deform plastically in compression up to a strain of 3.8% and possess a Young’s modulus of 78 GPa. The Sn- and Ga- containing BMG rods reach respectively a plastic strain of 6.1% and 4.7%, and a Young’s modulus of 72 and 63 GPa. Corrosion tests were performed by electrochemical experiments, and the highest pitting resistance was observed for Ti40Zr10Cu32Pd14Sn4 (pitting overpotential ηpit = 446 mV) compared to Ti40Zr10Cu32Pd14Ga4 (379 mV) and Ti40Zr10Cu36Pd14 (183 mV). The results of live/dead assay and cell viability revealed excellent biocompatibility for the Ga-containing BMGs.
