在机械制造业中新的难加工材料的出现,要求进一步改进熟知的刀具材料和研制新材料。改进刀具的前景是完善在低温下(对用CVD法涂复的耐磨涂层来说为550℃以内,对用PVD法涂复的耐磨涂层来说为200℃以内)向硬质合金和高速钢涂复耐磨涂层的过程。精加工钢材时,明显的发展趋势是制造以碳化钛为基础的金属陶瓷。在淬火钢和难加工材料的加工方 The emergence of new, difficult-to-machine materials in the machinery manufacturing industry calls for further improvement of well-known tool materials and the development of new materials. The prospects for improved tooling are perfected at low temperatures (up to 550 ° C for wear-resistant coatings coated with CVD and within 200 ° C for wear-resistant coatings coated with PVD) And high-speed steel coated with wear-resistant coating process. When finishing steel, the clear development trend is to manufacture titanium carbide-based cermets. In hardened steel and difficult to machine materials processing side
