The high-entropy alloy coatings reinforced with nano oxides were synthesized by the atmospheric plasma spraying (APS). The crystal structure, microstructure, surface morphology, hardness and wear resistance properties of the CoCrFeNiAl and CoCrFeNiMo high-entropy alloy coatings are investigated. For CoCrFeNiAl high entropy coating (HEC) not only has high hardness (573 ± 19 Hv_0.1) but also has good wear resistance [The coefficients of friction (COF) is 0.49 ± 0.04]. The transition of the wear mechanism obviously appears between the two HECs. The influences of the structure, composition and hardness on the tribological behavior of high-entropy alloy coatings were discussed in details.

通过大气等离子喷涂（APS）合成了纳米氧化物增强的高熵合金涂层。研究了CoCrFeNiAl和CoCrFeNiMo高熵合金涂层的晶体结构，显微组织，表面形貌，硬度和耐磨性。对于CoCrFeNiAl，高熵涂层（HEC）不仅具有高硬度（573±19 Hv _0.1），而且具有良好的耐磨性[摩擦系数（COF）为0.49±0.04]。磨损机制的过渡显然出现在两个HEC之间。详细讨论了结构，组成和硬度对高熵合金涂层摩擦学性能的影响。
