采用等离子喷涂方法在CuNiCoBe 合金表面制备了单一WC－Co涂层和Mo／WC－Co复合涂层。利用扫描电镜（SEM）对涂层的微观形貌进行观察分析，并对涂层的结合强度、抗热震性能以及涂层的摩擦性能分别进行了研究。结果表明：涂层为典型的层叠结构，涂层与基体、涂层与涂层之间结合良好；复合涂层与基体间的结合强度及涂层的抗热震性能均优于单一涂层；WC－Co涂层的平均摩擦系数随着温度的升高而下降。
採用等離子噴塗方法在CuNiCoBe 閤金錶麵製備瞭單一WC－Co塗層和Mo／WC－Co複閤塗層。利用掃描電鏡（SEM）對塗層的微觀形貌進行觀察分析，併對塗層的結閤彊度、抗熱震性能以及塗層的摩抆性能分彆進行瞭研究。結果錶明：塗層為典型的層疊結構，塗層與基體、塗層與塗層之間結閤良好；複閤塗層與基體間的結閤彊度及塗層的抗熱震性能均優于單一塗層；WC－Co塗層的平均摩抆繫數隨著溫度的升高而下降。

The WC-Co coating and Mo/WC-Co composite coating were deposited on the CuNiCoBe alloy sur-face by plasma spraying method .The coating morphologies were observed by Scanning electron microscopy , the adhesion strength , thermal shock resistance and friction properties of the coating were studied .The results show that the coating has a typical lamellar structure and a good bonding between the coating and substrate , the coat-ing and the coating;the bond strength and thermal shock resistance of the composite coating are better than the single coating;the average friction coefficient of WC -Co coating decreases with the increase of temperature .
