【摘要】 应用气相沉积技术可以获得微米级或纳米级的单层或多层新颖材料。其中在机械部件和加工工具上硬质膜的应用一直是人们最感兴趣的重要方面。目前,对涂层硬质合金主要应用 CVD 技术,涂层高速钢和高合金钢主要应用 PVD 和 PECVD 技术。本文阐述具有高淬透性、二次硬化能力和淬火加热奥氏体化温度接近 CVD 涂覆温度的工具钢,在 CVD 涂覆的前后采用强化的热处理和表面保护的工艺方法进行处理可以获得优良的基材性能和优异 CVD 涂层的部件,将大大提高部件的使用寿命。我们在这方面应积极开展相应的研究工作。更多还原

【Abstract】 Some new typical materials with single layer or multiplayer structure of the grade of micrometer or nanometer can be made by means of vapor phase deposition technique.It is the most important and interesting to coat mechanical parts and tools with the hard deposited films.At present,coating the carbide is produced with CVD methods and coating the HSS and high alloy steels with PVD and PECVD methods.In this paper the author’s index out that those tool steels,with high hardenability,secondary hardening behavior and austenitizing temperature near CVD temperature,can be CVD-coated in order to gain the excellent properties of the superficial deposited layer but also the substrate.As a matter of course,those steels must be treated through the strengthening heat treatment in vacuum or protective atmosphere before and after CVD process.更多还原
