One of the most important factors for increasing durability turbine engines is use blades characterized by best possible convergence thermophysical properties protective coating and base material blade. The aim research was to evaluate heat resistance prototype two-layer coatings applied blades. inner layer enables shaping outer used thermal protection blade material. plasma spraying, diffusion...

In this study, two modified MCrAlY-type coatings were prepared by the same arc ion plating process. ‘Gradient annealing’ and ‘gradient annealing plus preoxidation’ adopted as post-treatments for coatings. A two-layer scale of a mixed oxide layer pure alumina with next to substrate was formed on latter coating. cyclic hot corrosion test carried out them conventional coating reference. The kineti...

Abstract In this study, MCrAlY coatings with different microstructures were prepared by arc ion plating to investigate the mechanical and thermal shock properties of coatings. The results show that overall possessed similar hardness (7.66 GPa–9.20 GPa) but lower elastic modulus (119.07 GPa–148.02 GPa), compared those conventional sprayings. microstructure coating had a significant impact on pro...
