摘　　要：为了获取一种准确有效的Au镀层显微硬度测试方法以满足航天领域的应用需求,本文采用显微维氏硬度法及纳米压痕硬度法研究了Au镀层在不同测试方法及不同测试载荷下的显微硬度值及其标准方差,并依据相关检测技术标准的要求,就检测方法的可行性进行了分析。结果表明:本文优选的Au镀层显微维氏硬度检测参数及测试数据的判定范围满足标准QJ482,同时还能满足压痕深度小于镀层厚度的1/7,避免了基体对测试结果的影响,测试方法可行,测试数据有效。In order to find a precise and effective method to characterize the micro-hardness of Au coating to meet the demands for space applications,the micro Vickers hardness test method and Nano-indentation test hardness method were selected under different test methods and different load conditions.According to the requirements of the relevant technical standards, the feasibility of the test method is analyzed.The results show that the optimized micro Vickers hardness test parameters and results meet the requirements of standard QJ482.The depth of indentation is less than 1/7 of the thickness of the Au coating, so that the impact of matrix material on hardness test results is avoided.The test method is feasible and the results are valid.
