采用钨极氩弧焊熔覆技术在钢表面原位合成金属间化合物基复合涂层TiC/Ni3Al.研究了复合涂层的组织和抗冲蚀性能,探讨了涂层的形成及抗冲蚀机理.结果表明:采用钨极氩弧焊熔覆技术在钢表面制得的TiC/Ni3Al复合材料无杂质相,颗粒分布均匀；随着预置层中(Ti+C)含量的提高TiC颗粒的数量增加,材料的硬度提高；涂层与基体之间呈现良好的冶金结合,从熔合线到涂层外表面TiC颗粒的形态逐渐从细小球形转变为等轴状、树枝状；Al、Ni、Fe元素呈梯度变化,而Ti元素主要以TiC颗粒物的形式存在于涂层中.在不同冲蚀角度下复合涂层的冲蚀量均显著小于H13钢和0Cr 17Ni7Al钢,表现出优异的抗冲蚀性能.
