中文摘要:
      近年来,我国汽车产业迅猛发展,汽车机械零部件的需求给我国切削加工业带来了发展机遇和挑战。汽车安全性和舒适性的要求,国家节能减排、绿色制造的发展战略,指引切削技术向高速、高效、高精、绿色、智能方向发展,对刀具材料的使用性能也提出了更高要求。 TiCN 涂层刀具因具有高硬度和高耐磨性被大量应用,尤其是在有色金属及合金的切削加工上具有明显优势。综述了 TiCN 涂层的微观结构,指出 C 原子具有细化晶粒和抑制柱状晶形成的作用,涂层的结晶度和择优取向随 C 含量的改变而变化。总结了 TiCN 涂层的主要性能特点,包括硬度和致硬机理、耐磨性和减摩机理、热稳定性和热失效机制。介绍了 TiCN 涂层的沉积原理,指出各种制备方法的优缺点和关键工艺参数。分析了以 TiCN 为基进行改性获得的涂层的国内外最新研究现状,提出对 TiCN 涂层进行多层化、多元化以及纳米多层化,是进一步提高该涂层在高温条件下综合性能的方法,也是该涂层为适应高速切削、干式切削等新切削技术要求的发展方向。
英文摘要:
      In the last few years, the automobiles industry has grown by leaps and bounds. The requirements of automobiles machine parts provide cutting industry with more chances and challenges. The demands of safety and comfort of automobiles as well as the development strategies of reduction of pollutant emission and green technologies, guide cutting technology development towards high speed, high efficiency, high accuracy, green and intelligent. It also has more requirements on the performance of tool materials. TiCN coatings are widely used, especially in cutting non-ferrous metals and alloys, for its high hardness and high wear resistance. This article summarized the micro structure of TiCN coatings, and pointed out that carbons had an effect of refining grains and restraining the formation of columnar structure. Crystallization and preferred orientation of TiCN coatings were changed with the variation of carbon content. The main performance features of TiCN coatings were summarized in details, including hardness and hardening mechanism, wear resistance and antifriction mechanism, thermal stability and thermal failure. This review also introduced the deposition principle of TiCN coatings and pointed out the merit and demerit of the various manufacturing methods and the key process parameters. The latest researches on the improvement of TiCN coatings at home and abroad were analyzed. It concluded that multiple stratification, multi-alloying and nano-crystallization tendency of TiCN coatings were the ways to improve the overall performance at elevated temperatures, and they were also development directions of coatings to meet the demands of new cutting techniques such as high speed cutting and dry cutting techniques.
