Oxidation behavior of Ni(Co)CrAlYHf(Si) coatings on DS superalloy at 1 150 ℃ Huang Zhao-hui(黄朝晖), Tan Yong-ning(谭永宁), Zhao Xi-hong(赵希宏), LI Jian-ping (李建平), ZHANG Qiang(张 强) National... Ni(Co)CrAlY coatings were deposited by EB-PVD method on a DS superalloy of Ni-Al-Cr-Co-W-Mo-Ta-Hf system. SEM, XEDS and XRD were used to study the oxidation behavior of the coatings. The two coatings......
