摘　　要：采用落砂法进行铝合金阳极氧化膜的耐磨性试验,分析了试验过程中各因素对试验结果的影响,并对其试验结果的测量不确定度进行了评定。结果表明:试验结果误差的主要来源为阳极氧化膜膜厚的测量误差和消耗磨料质量的测量误差。铝合金阳极氧化膜耐磨性试验的磨耗系数为351g·μm^-1;取包含因子k=2,其扩展不确定度U(f)=30g·μm^-1。The wear resistance test of anodized aluminum alloy film was carried out by the shakeout method.The influence of various factors on the test results were analyzed,and the measurement uncertainty of the test results were evaluated.The results show that the main errors of the test results were the measurement errors of the thickness of the anodized film and the measurement errors of the mass of the consumed abrasive.The wear coefficient of anodized aluminum alloy film was 351 g·μm^-1.Taking the inclusion factor k=2,the expanded uncertainty U(f)=30 g·μm^-1.
