高熵合金涂层具有良好的耐摩擦磨损和耐腐蚀性能，是一种重要的结构材料。研究了常压等离子喷涂（APS）法制备的AlCoCrFeNi高熵合金涂层的显微组织、表面形貌、硬度、摩擦磨损和耐蚀性能。随着APS功率的增加，涂层的耐摩擦磨损和耐腐蚀性能同时提高。阐明了APS工艺对合金微观组织和力学性能的影响。详细讨论了AlCoCrFeNi HEAC的摩擦磨损机理和腐蚀行为。
High-entropy alloy coatings (HEAC) exhibit good frictional wear and corrosion resistances, which are of importance for structure materials. In this study, the microstructure, surface morphology, hardness, frictional wear and corrosion resistance of an AlCoCrFeNi high-entropy alloy coating synthesized by atmospheric plasma spraying (APS) were investigated. The frictional wear and corrosion resistance of the coating are simultaneously improved with an increase of the power of APS. The influence of the APS process on the microstructure and mechanical behavior is elucidated. The mechanisms of frictional wear and corrosion behavior of the AlCoCrFeNi HEAC are discussed in detail.
