چکیده
Materials can be subjected to severe wear and corrosion due high temperature, pressure mechanical loads when used in components for the production of geothermal power. In an effort increase lifetime these thus decrease cost maintenance High-Entropy Alloy Coatings (HEACs) were developed with different coating techniques anti-wear properties. The microstructure, tribological properties CoCrFeNiMox (at% x = 20, 27) HEACs deposited by three technologies—high-velocity oxygen fuel (HVOF), laser cladding (LC) electro-spark deposition (ESD)—are presented this study. relationship between surface morphology microstructural as-deposited coatings their friction behavior is assessed evaluate candidacy as environment. rates lower HVOF compared LC ESD-produced coatings. Similarly, a higher hardness (445 ± 51 HV) was observed HEACs. mixed FCC, BCC structure extent σ + µ nano precipitates are considered responsible increased improved performance findings from study valuable development wear-resistant HEAC energy industry applications where encountered.

Soft Magnetic Properties of High-Entropy Fe-Co-Ni-Cr-Al-Si Thin Films
Soft magnetic properties of Fe-Co-Ni-Al-Cr-Si thin films were studied. As-deposited Fe-Co-Ni-Al-Cr-Si nano-grained thin films showing no magnetic anisotropy were subjected to field-annealing at different temperatures to induce magnetic anisotropy. Optimized magnetic and electrical properties of Fe-Co-Ni-Al-Cr-Si films annealed at 200 ◦C are saturation magnetization 9.13 × 105 A/m, coercivity 79...

The zirconia stabilized by 3mol % Y2O3 (3YSZ) was applied onto the surface of the magnesium alloy AZ91D using electrophoretic deposition (EPD) from a non- aqueous solution. A Ni-P interlayer between the substrate and YSZ coating was also prepared by electroless plating. Finally, coatings were heat treated in control atmosphere at 400 °C. The preparation, microstructure and corrosion resistance ...
