氧化物及复合氧化物陶瓷材料一般具有硬度高、熔点高，热稳定性及化学稳定性好的特点。用作涂层可以有效提高基体材料的耐磨损、耐高温、抗高温氧化，耐热冲击，耐腐蚀等性能。氧化物陶瓷材料主要有：Al2O3 , TiO2, Cr2O3 ,ZrO2等。这些陶瓷材料由于熔点高，热传导率低，以粉末状态送入火焰或等离子焰流中时，与金属粉末相比较难完全熔化。因此使用时采用粒度较小的粉末，并采用高温的等离喷涂。

Oxides and composite oxide ceramic material generally have high hardness, high melting point. Thermal stability and chemical of guan good characteristics. Used as a coating  improve the wear resistance of substrate material. High temperature resistant. High temperature oxidation resistance. Heat shock. Corrosion resistance performance. The oxide ceramic material are mainly Al2O3, TiO2, Cr2O3, ZrO2 etc. These ceramic materials due to their high melting point. Low thermal conductivity in the powder  flame of plasma flame streamed.  Compared wite metal powder is difficult to completely melt.  using the grain powder. using high temperature plasma spraying.
