摘要

高温环境运动部件遭受着严重的摩擦磨损破坏，对其表面防护涂层提出了严苛要求。高熵合金具有良好的成分设计灵活性和优异的综合性能，可通过成分调控获得低摩擦系数、高耐磨涂层，从而实现高温服役部件的高效防护。为了获得高温服役运动部件低摩耐磨防护涂层，通过磁控溅射制备了VAlTiCr 基高熵合金涂层，研究了引入不同元素(Mo，W 和Si)和热处理温度(700、800 和900 ℃)对高熵合金涂层晶体结构及高温摩擦学性能的影响。结果表明:制备态VAlTiCrSi 涂层为非晶结构，而VAlTiCrMo 和VAlTiCrW 涂层均呈现BCC 固溶体结构。热处理后涂层在700 ℃大气环境的摩擦学性能测试显示，随着热处理温度的升高，3 种涂层的摩擦系数及磨损率均先降低后提高，且在800 ℃热处理后，VAlTiCrMo、VAlTiCrW 和VAlTiCrSi 涂层均具有最佳的摩擦学性能。V2O5和AlVO4等氧化物起主要润滑作用，VAlTiCrMo 涂层较VAlTiCrSi 和VAlTiCrW 涂层具有更优的摩擦学性能，其摩擦系数低至0.21，磨损率仅为9.98×10-5mm3/(N·m)。通过高熵合金涂层元素调控和热处理为获得苛刻环境高性能防护涂层的研究提供了数据参考。

Abstract

Motion devices in high temperature environments suffer serious friction and wear damage，which puts forward strict requirements for their surface protective coatings.High-entropy alloys have good composition design flexibility and excellent comprehensive properties.Low friction and high wear resistant coatings can be obtained through composition regulation，thereby achieving efficient protection of high temperature service components.In order to obtain low friction and wear resistant protective coatings for moving parts servicing in high temperatures in this paper，VAlTiCr-based high-entropy alloy coatings were prepared by magnetron sputtering.The effects of different elements (Mo，W，and Si) and heat treatment temperatures (700，800，and 900 ℃) on the crystal structure and high temperature friction properties of high-entropy alloy coatings were studied.Results showed that the as-prepared VAlTiCrSi coating was amorphous，while the VAlTiCrMo and VAlTiCrW coatings exhibited BCC solid solution structure.The tribological properties of the coatings after heat treatment were tested at 700 ℃，which showed that with the increase of heat treatment temperature，the friction coefficient and wear rate of the three coatings decreased first and then increased；And after heat treatment at 800 ℃，VAlTiCrMo，VAlTiCrW and VAlTiCrSi coatings all had the best tribological properties.Oxides such as V2O5 and AlVO4 played a major role in lubrication.VAlTiCrMo coating has better comprehensive friction performance than VAlTiCrSi and VAlTiCrW coatings.The friction coefficient was as low as 0.21，and the wear rate was only 9.98×10-5mm3/(N·m).Therefore，the element regulation and heat treatment of high-entropy alloy coating could provide data reference for the research of the high-performance protective coating serving in harsh environments.
