采用包覆、机械混合与团聚烧结工艺制备了多尺度WC-17Ni和ZYT10001A(WC-17％ Co),WCTN(WC-17％ Co)金属陶瓷粉末.用3种粉末冷喷涂沉积涂层,运用扫描电镜分析了涂层的组织结构、X射线衍射表征粉末与涂层的物相结构,用压入法测定了涂层的显微硬度、弹性模量和断裂韧性.研究结果表明,3种粉末沉积的涂层均具呈现致密的组织结构,涂层中的相结构没有发生变化.3种涂层的显微硬度、弹性模量和断裂韧性分别在(650.8±40.4)～ (1350.0±115) HV0.3、(182.6±66.6) ～(309.9±52.9)GPa和(13.12±4.44)～ (24±1)MPa·m1/2之间变化,其中以ZYT10001A(WC-17％ Co)涂层的硬度值最大及断裂韧性值最小.
