简介:摘要:表面涂镀技术可以根据零部件或者元器件的用途方便地选择或者设计表面材料的成分,控制表面性能,因而应用广泛。TiN是迄今应用最广的硬质涂层,而TiN涂层的合金化使得TiN涂层的性能进一步优化。本文综述了TiN涂层合金化的研究现状和进展,展望了TiN涂层合金化的发展前景。关键词:TiN涂层;合金化;研究现状1前言在提倡资源合理化利用的今天,采用表面涂镀技术取代整体合金化,赋予材料表面特殊的性能,一方面可以节约原材料,另一方面可以大幅度提高零部件的耐磨性、耐蚀性,而且提高了劳动生产率,降低了生产成本。据统计,全世界各发达国家仅仅因磨损、腐蚀造成的经济损失就占各国国民生产总值的3%-5%[1].因此,提高材料表面的耐磨性和耐蚀性具有重要的现实意义。而物理气相沉积(PVD)TiN涂层是应用最广泛的一种表面强化技术[2]......
