元素掺杂对TiAlN涂层刀具性能影响的研究进展
Research progress in effect of element doping on performance of TiAlN coated cutting tools
摘要
Abstract
With the rapid development of China's manufacturing industry and the emergence of difficult-to-machine materials,there is an urgent need for cutting technology to continuously update and iterate,and the development of cutting tools has become a key factor in improving processing efficiency. In recent years,coating technology has become an effective way to improve the cutting performance of cutting tools. In particular,TiAlN coating has been widely used in cutting tools due to its good wear resistance and stability. However,the traditional TiAlN coated tools have made it difficult to bear the harsh conditions of thermo-mechanically-chemo multiple coupling. How to form solid solution strengthening and fine grain strengthening by element doping,for improving the cutting performance of TiAlN coated tools conveniently and efficiently,has become a research hotspot in this field. Given this problem,the action mechanism and preparation method of TiAlN coating were summarized,the microstructure and phase structure of the coatings obtained by different methods were analyzed,the limitations of TiAlN coating due to oxidation and phase transformation in high temperature were described,and the effects of doping Si,C,Cr,B and V elements on the microstructure,hardness,wear resistance,oxidation resistance and tool life of TiAlN coating were reviewed. Finally,the future development of TiAlN coated tools is summarized.关键词
