| Abstract: | A new ceramic coating for sand casting is presented, and the effects of rare earth oxides on the microstructure and properties of the nanometer Al2O3 ceramic coating have been investigated. The results show that adding suitable amount of rare earth oxides can lower the sintering temperature of Al2O3 ceramic coating and increase its density and surface hardness, thereby greatly increasing the high-temperature shielding property and erosion-resistant ability of ceramic coating to liquid metal, which played a ... |
