摘要
涂层刀具是一种先进的切削工具,由于其优良的切削性能而备受人们关注。综述了各种涂层刀具的切削性能及其在切削加工中的应用现状。涂层刀具的种类从单涂层刀具发展到多元复合涂层刀具;涂层的层数从单层发展到多层,而且各单涂层的厚度趋于纳米化。因此,纳米复合涂层刀具将是今后涂层刀具的应用热点。与未涂层刀具相比,涂层刀具可有效地延长刀具的使用寿命,使刀具获得良好的综合机械性能,从而大幅度地提高其机械加工效率。
The coated cutting tools are a kind of advanced cutting tool with good cutting performance. ting performance and application of every coated cutting tool in cutting machining are outlined. They have been developed from single metal coated cutting tools to multi-constituent coated cutting tools. Then the coatings have been improved from the single layer to multilayer, and the nano-composite coatings are the development trend. So the nanocomposite coated cutting tools will be the application hotspot in the future. The service life of coated cutting tools and their comprehensive mechanical property can be enhanced more effectively than their uncoated counterparts, thus the mechanical processing efficiency is improved largely.
