A PVD process_cathodic arc plasma ion plating was used to deposit Ni_Al films on Inconel 600 superalloy. The oxidation behaviors of PVD Ni_Al coating and the thermal sprayed CoCrAlY coatings were revealed and compared by performing cyclic thermal oxidation test at 1 100 ℃ to evaluate its feasibility. Experimental results showed that the films with different compositions of Ni 62 Al 38 , Ni 63 Al 37 and Ni 69 Al 31 could be obtained when using Ni 52 Al 48 , Ni 60 Al 40 and Ni 70 Al 30 as targets, respectively. During the cyclic thermal oxidation test, …
