摘要

随着工业对切削精度和效率的要求不断提高以及钛合金等难加工材料的出现,具有优异综合性能的新型硬质涂层材料的开发与改性成为研究热点。CrAlSiN涂层因其具有纳米复合结构而表现出超高的硬度,同时具有优异的抗高温氧化和耐磨性能,获得了研究者的广泛关注。本文归纳了CrAlSiN涂层的微观结构、力学性能、耐磨性能、高温抗氧化性、高温热稳定性、耐蚀性和切削性能的特点及相关机制;阐述了涂层中Al和Si含量对其微观结构和性能的影响规律及作用机理;综述了元素掺杂(掺Ti、V、O、Mo等)与微观结构设计(添加过渡层、多层和梯度结构)对CrAlSiN涂层微观结构与性能的影响和作用机制;最后对CrAlSiN涂层的发展与研究方向进行了展望。

Abstract

With the increasing improvement of industrial requirements for cutting accuracy and efficiency and the emergence of difficult-to-machine materials such as titanium alloys, the development and modification of new hard coating materials with excellent comprehensive properties has become a research hotspot. The CrAlSiN coating has attracted widespread attention from researchers due to its ultra-high hardness exhibited by its nanocomposite structure, along with its excellent resistance to high-temperature oxidation and wear. In this paper, the characteristics and related mechanisms of the microstructure, mechanical properties, wear resistance, high-temperature oxidation resistance, high-temperature thermal stability, corrosion resistance and cutting performance of CrAlSiN coatings were summarized. The influencing law and mechanism of Al and Si content in the coatings on microstructure and performance was described. The effects and mechanism of element doping (doping with Ti, V, O, Mo, etc.) and microstructure design (adding transition layer, multi-layer, and gradient structure) on the microstructure and properties of CrAlSiN coatings were reviewed. Finally, the development and research direction of CrAlSiN coatings were prospected.
