摘　　要：本文阐述了韦氏硬度计的检测原理,指出了压针磨损对检测结果产生影响,从仪器检测原理分析了压针磨损对检测结果有影响的原因,并计算了压针磨损到何程度将导致检测结果偏差超出允许值。文章认为韦氏硬度计的压针是关系到检测结果准确性的关键因素,使用过程须经常检查压针。The principle of Webster Hardness testing by using Webster Hardness Tester is described in this paper.The impacts on the test results which caused by pressure—pin wear are analyzed.Pointed out when the result will beyond the allowable value because of pressure—pin wear.We should always check the pressure-pin because the it is the key factor in the accuracy of test results.

关 键 词：韦氏硬度 铝合金 压针 磨损 检测 偏差
