Ceramic coating prepared by slurry method has been applied to the metal surface for its excellent properties which can enhance the reliability and durability of industrial equipment. While for copper as the substrate, a transition coating is needed between ceramic coating and copper substrate to solve the problem caused by the difference of their thermal expansion coefficients. In this paper, NiCoCrAlY transition coating was prepared by atmospheric plasma spraying (APS) and ceramic top coating was prepared by slurry method. The results show the transition coating plays a key role in obtaining excellent properties. The thermal shock resistance life at 600 ℃ reached 110 cycles and the bonding strength was 15.04 MPa. The oxidation resistant effect δ of the ceramic coating can reach 87.29% at 800 ℃. Thus, the ceramic coating prepared can be applied to copper equipment for protection against harsh environments.
