abstract:One of the most promising materials for coating applications is Yttria stabilized Zirconia. In the present work, the structure and oxidation the resistance Yttria stabilized Zirconia coatings deposited with atmospheric plasma spray and detonation gun are examined. Both coatings have similar chemical composition and crystal structure. However, atmospheric plasma spray coatings are non-uniform due to the presence of dispersed pores and voids in the coating which do not communicate with each other and thus have insignificant effect on the coating protection. The detonation gun coating is more compact with lower porosity. In any case both of them have similar oxidation performance.
