Copper is usually applied in severe environments such as extreme temperature, wear, or corrosive conditions which seriously affect the service life of copper equipment. In this study, a ceramic coating was prepared by slurry method. The slurry which was coated on the bond layer of NiCoCrAlY was blended by aggregates of SiO2, Al2O3, and ZrO2 and binder of sodium silicate. The ceramic top coating was formed through sintering at 600 °C. The results show that the ZrSiO4 and Al2Si3O9 which play a key role in improving the properties are formed as the main phases in the ceramic coating. Furthermore, the bonding strength was tested to be 10.29 MPa and the wear rate reached 3.040 × 10−5 mm3/(m·N). After the test of 50 thermal cycles, the ceramic coating kept good condition. Thus, the coating prepared shows potential for copper protection in harsh environments.
