氧化物及復(fù)合氧化物陶瓷材料一般具有硬度高、熔點(diǎn)高，熱穩(wěn)定性及化學(xué)穩(wěn)定性好的特點(diǎn)。用作涂層可以有效提高基體材料的耐磨損、耐高溫、抗高溫氧化，耐熱沖擊，耐腐蝕等性能。氧化物陶瓷材料主要有：Al2O3 , TiO2, Cr2O3 ,ZrO2等。這些陶瓷材料由于熔點(diǎn)高，熱傳導(dǎo)率低，以粉末狀態(tài)送入火焰或等離子焰流中時(shí)，與金屬粉末相比較難完全熔化。因此使用時(shí)采用粒度較小的粉末，并采用高溫的等離噴涂。

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.
