摘要
WC金属陶瓷涂层因具有优良的耐磨损和耐腐蚀性等性能而在煤化工、石油化工、航空航天等领域得到了应用。针对超音速火焰喷涂技术在常用钢铁材料基体上制备的WC金属陶瓷涂层,介绍了WC金属陶瓷涂层中粉末粒径、元素含量、涂层的厚度与喷涂角度对涂层组织和性能的影响。从涂层耐腐蚀性、耐磨损性、显微硬度、结合强度以及孔隙率等方面,对涂层性能的相关研究进展进行了总结和分析。最后,提出了WC金属陶瓷相关研究中存在的问题及未来提升WC金属陶瓷性能的研究方向。
WC cermet coating has been used in coal chemical industry,petrochemical industry,aerospace and other fields because of its excellent wear resistance and corrosion resistance.For the WC cermet coating prepared by the supersonic flame spraying technology on the common steel material matrix,the effects of powder particle size,element content,coating thickness and spray angle on the microstructure and properties of the WC cermet coating was introduced.The research progress of coating properties was summarized and analyzed from the aspects of corrosion resistance,wear resistance,microhardness,bonding strength and porosity.Finally,the problems existing in the research of WC cermet and the research direction of improving the properties ofWC cermet in the future were put forward.
