摘要
通过两种较为先进的热喷涂方式,在以球墨铸铁为材料的气缸套内壁制备WC-Co合金涂层。并进行了结合强度、硬度和耐蚀性测试。结果表明:该涂层可提高缸套的硬度、强度和耐蚀性,延长了其使用寿命。
By adopting two types of advanced thermal spraying methods, WC-Co alloy coating was prepared on the inner wall of cylinder liner taking ductile cast iron as material. The bonding strength, hardness and corrosion resistance were measured. The results indicate the hardness, strength and corrosion resistance of the cylinder liner improve by WC-Co alloy coating, meanwhile its service life improves.
