Summary: The HVOF spray process was used to create nickel-based alloy coatings with different chromium contents (NC-A, 7.15 wt%; NC-B, 16.98 wt%). The tribocorrosion test revealed a mechanical plowing effect on the coatings at low applied potential (< +100 mVSCE), and intensified corrosion effect exacerbated the wear behavior of the coatings at higher potential (>+300 mVSCE). Quantitative analyses showed that the total weight loss (Wtotal) of the coatings significantly increased with growing potential loading, and the synergic effects between corrosion and wear played a crucial role in the overall weight loss.

Summary: This study investigated the microstructure, high-temperature oxidation properties, and mechanism of a non-equiatomic Fe-Cr-Ni-Al medium entropy alloy (MEA). The microstructural observation revealed coarse grains and evenly distributed cuboidal precipitates within the grains. The alloy exhibited excellent high-temperature oxidation resistance due to the formation of a dense, stable Al2O3 layer, regardless of temperature conditions, and no breakaway oxidation occurred.

Summary: The oxidation resistance of AlCoCrFeNi high entropy alloy coating was investigated, as well as the effect of Si modification on oxidation resistance. AlCoCrFeNiSix (x = 0, 0.15, 0.3) coatings were prepared on 316L stainless steel substrate using atmospheric plasma spray. The evolution process and oxidation kinetics of the thermal grown oxide (TGO) layer were discussed, and the growth model of the TGO layer was established. The results showed that Si0.15 coating with a TGO layer consisting entirely of Al2O3 had the lowest oxidation rate.

Summary: The corrosion properties of four nickel-based cladding layers under chlorine-induced high-temperature corrosion were evaluated using the thickness loss rate. The results show that increasing the Cr content alone does not improve corrosion resistance, but instead worsens internal corrosion. The effect of Mo on enhancing corrosion resistance in laser cladding technology is closely related to its content and distribution. Transverse penetration cracks tend to occur in NiO surrounded by NiCr2O4, while the presence of short rod-like NbO2 enhances the mechanical properties of the NiO layer and eliminates such cracks.

Summary: This study investigated the effects of hydrogen charging on the oxide film of Ni, Cr, and Alloy 690 in high-temperature water. The results showed that hydrogen charging caused amorphization in the inner layer of Cr, thinning of the oxide film in Ni, and the presence of cavities along the boundary of inner oxide and matrix. The oxide film of Alloy 690 exhibited a mixed feature of Ni and Cr. The diffusion of hydrogen into the solution not only affected the thermal stability of the oxide film but also hindered the precipitation of outer oxide.

Summary: The addition of Cr nanoparticles to the PEO electrolyte improves the properties and coating composition of the layers. By incorporating Cr nanoparticles into PEO-coated Mg alloy, the effects of nanoparticles and different voltages on coating formation, microscopic morphology, and phase composition were investigated. The results showed significant improvement in corrosion resistance when the final voltage was set to 460 V and the concentration of Cr nanoparticles was 1 g/L. The presence of oxidized Cr nanoparticles increased the growth rate of the coating and sealed its open pores, resulting in improved corrosion resistance.

Summary: Deposition of Ni-Cr through cold spraying using air as process gas is explored in this study for power sector applications. Coatings deposited at higher temperature exhibit superior performance due to strong inter-splat boundaries, resulting in improved porosity, oxidation resistance, and spallation resistance. The bonding conditions used in this study meet the requirement for inter-splat bonding, with an estimated fraction of bonded inter-splat boundaries of approximately 100% at 20 bar 800 degrees C.

Summary: Medium-entropy alloys (MEAs) and high-entropy alloys (HEAs) are good candidates for high-temperature applications due to their exceptional thermal stability. However, the presence of expensive cobalt elements in most of these alloys has limited their further promotion and application. Therefore, it is crucial to develop low-cost MEAs with superb oxidation resistance.

Summary: Surface deformation of Ni and Fe alloys contributes to improved oxidation resistance at low and intermediate temperatures. The beneficial effect is not solely due to fast diffusion mediated by high densities of dislocations and grain boundaries, but rather by diffusion-induced grain boundary migration (DIGM). DIGM enables faster Cr transport to the surface and selective Cr oxidation, resulting in improved oxidation resistance.

Summary: This study investigates the changes of ZrO2/Cr composite coating under high-energy ion irradiation. The results show that similar extents of grain growth and partial healing of microcracks are observed in the ZrO2 layer after irradiation. Monoclinic to tetragonal transformation of ZrO2 and the formation of an amorphous (Zr,Cr)O phase at the ZrO2/Cr interface are identified in the Ni-irradiated sample. Large amounts of dislocation loops and small cavities are observed in the Cr layer, while fewer loops are found in the ZrO2 layer in both samples. Irradiation also leads to significant growth of surface Cr oxides.

Summary: In this study, Ti-xFe (x = 3,5,9 wt%) alloys were surface modified by micro-arc oxidation (MAO) to improve their antimicrobial properties and biocompatibility. The results showed that increasing the oxidation voltage greatly enhanced the roughness and hydrophilicity of Ti-xFe-MAO alloys. The Ti-xFe alloys micro-arc oxidized at 250 V and 300 V exhibited improved corrosion resistance and excellent antimicrobial and cytocompatibility properties, making them suitable for orthopedic implant materials.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
