摘　　要：采用两种方法对套筒等离子喷焊层元素分布进行了电子探针分析(EPMA),根据元素分布结果计算喷焊层稀释率。对两种检测结果进行对比,分析导致测试数据产生差异的原因及对最终结果的影响。An electron probe micro-analysis （EPMA） was performed to the element distribution in plasma surfaced layer over a gas turbine bush by two methods, based on which the rate of dilution was calculated. By comparing the test results of two methods, causes leading to the difference of test data were analyzed, while the influence of data difference on the final results was studied.
