Formation of non FP plate-out High density and homegeneity ceramic thin coating onto the surface of high strength Ni-based super alloy by ion plating technique

Ishiyama, Shintaro

AlO and ZrO coating test was performed on the surface of Ni based super alloy by ion plateing technique and high density and homegeneity ceramic thin coating with the thichkness of 4m was formed on the specimen surface. 1173K-RT heat cycle and FP plat-out tests were performed with these coate specimens and no damage was found under 100 cycles and there is no plate-out onto the these specimens.
