摘要(Abstract)：

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。
