人们为了将粉体的优异性能发挥到极致，通常会对超细粉体进行表面包覆处理以改善颗粒的表面特性和提高其分散性能，以达到工业应用要求。为了进一步提高修复关重件所需材料的耐磨损、抗氧化、耐腐蚀等综合性能，我们决定采用高熵合金基包覆陶瓷增强相来提高材料性能，并通过球磨、烧结、破碎等方法制备了CoCrFeNiTi高熵合金以及CoCrFeNiTi/cBN、CoCrFeNiTi/SiC、CoCrFeNiTi/WC、CoCrFeNiTi/SiC-Y₂O₃等高熵合金基包覆陶瓷增强相复合材料，并对高熵合金对陶瓷增强相的包覆情况、松装密度、粒度、流动性等进行了相关表征，并将制得的粉体通过等离子喷涂、激光熔覆等手段制成样品，对相关成品样品进行了性能表征与机理分析。

In order to maximize the excellent performance of powders, people usually carry out surface coating treatment on ultrafine powders to improve the surface characteristics of particles and enhance their dispersion performance, in order to meet the requirements of industrial applications. In order to further improve the comprehensive properties such as wear resistance, oxidation resistance and corrosion resistance of materials required for repairing critical parts, we decided to use High-entropy alloy matrix coated ceramic reinforcement to improve the material properties, and prepared CoCrFeNiTi High-entropy alloy and CoCrFeNiTi/cBN, CoCrFeNiTi/SiC, CoCrFeNiTi/WC, CoCrFeNiTi/SiC-Y2O3 and other High-entropy alloy matrix coated ceramic reinforcement composites through ball milling, sintering, crushing and other methods, The coating condition, loose density, particle size and fluidity of ceramic reinforcement phase by High-entropy alloy were characterized. The prepared powder was made into samples by Thermal spraying, laser cladding and other means, and the performance characterization and mechanism analysis of the relevant finished product samples were carried out.
