涂层厚度的控制至关重要，如果涂层厚度没有达到设计标准，对产品性能影响很大。利用实验室仪器搭建起一套涂层测厚试验平台，本试验中以铜、铁作为试验样品，用油漆作为涂层。利用射线穿过物质时的指数衰减规律I＝I0 e－μx ，用不同涂层厚度的标准样品进行标定以后，作出工作曲线；测量铜、铁两种基底上的涂层厚度，在涂层厚度介于0．01 g／cm2－0．06 g／cm2的范围内，相关系数分别为0．992和0．995，表明此测厚方法是可行的。

The control of coating’ s thickness is very important.If coating’ s thickness is not up to the standard, it will have a serious effect on the performance of the products.The test platform of coating’ s thickness meas-urement is built in the laboratory, Cu、Fe was used as the test sample, oil paint was used as coating in the ex-periment.The working curves are established after calibration using standard samples,taking advantage of the exponent attenuation law I=I0 e -μx , when ray is traversing matter;measuring coating’ s thickness on the base of Cu and Fe, under a condition that coating’s thickness is from 0.01 g/cm2 to 0.06 g/cm2, the correlation coef-ficient is 0.992 and 0.995 respectively, indicate that the measuring method is feasible.
