为解决某型发射装置转臂轴防护涂层耐用性差、材料寿命短等问题，进行了FeMnCoCrNi系高熵合金涂层材料的成分设计，通过试验验证和参数优化获得最佳工艺窗口。在转臂轴样件上制备了涂层试样，进行微观组织分析和综合性能测试。结果表明，涂层组织致密无缺陷，平均硬度约750 HV，抗磨损性能与基材相比提高了5.4倍，经120 h盐雾腐蚀后，涂层表面没有出现腐蚀坑或锈斑，满足转臂轴防护涂层长期使役性能需求。
In order to solve the problems of poor durability and short material life of the protective coating on the tumbler axis of a certain type of launcher, the composition design of FeMnCoCrNi high-entropy alloy coating material was carried out，and the optimal process window was obtained through experimental verification and parameter optimization. Preparing coating samples for microstructure analysis and overall performance testing. The results showed that the microstructure of coatings was dense, with an average hardness up to 750 HV. The wear properties was improved by 5.4 times compared to the substrate. After 120 hours of salt spray corrosion, there were no corrosion pits or rust spots on the surface of the coating, meeting the performance requirements.
