摘要:
采用非平衡磁控溅射技术在304L不锈钢和单晶硅基底上沉积WC/C多层复合涂层,利用扫描电镜、Raman光谱仪、X射线衍射仪等研究WC/C复合涂层的微观结构,采用纳米压痕仪、划痕测试系统测试涂层的力学性能,利用电化学测试系统和摩擦磨损试验机分别研究涂层在人工配置的海水环境的耐蚀性能和摩擦性能。结果表明:WC/C复合涂层内含有较多类石墨sp2键结构,存在WC1-x相并镶嵌在非晶碳基质中。较之于304L不锈钢基底,WC/C复合涂层在海水环境中表现出更好的耐蚀性与更优异的摩擦适应性。

Abstract:
The WC/C composite coating was deposited on the 304L stainless steel and silicon wafers by unbalanced magnetron sputtering technology. The microstructures of WC/C coating were analyzed by scanning electron microscope, Raman spectrometer and X-ray diffractometer. Mechanical properties were tested by nanoidenter and scratch tester.Electrochemical workstation and friction tester were used to investigate the corrosion resistance and tribological properties of WC/C coating in artificial seawater. The results indicate that plentiful graphite-like sp2 bonds are formed in the coating. It has the composite structure in which WC1-x phase is embedded in the amorphous carbon matrix. Compared to the 304L stainless steel,WC/C composite coating has better corrosion resistance and tribological adaptability in artificial seawater.
