金属涂层 - 涂层厚度测量 - 轮廓测量法

[中文适用范围]： 该文件规定了一种测量金属涂层厚度的方法，首先在涂层表面与其基材表面之间形成台阶，然后使用轮廓记录仪测量台阶高度。 它涵盖了适合轮廓测量方法特定应用的仪器特性和程序。 该方法适用于测量平面上 0.01 µm 至 1000 µm 的金属涂层厚度，如果采取适当的预防措施，还可测量圆柱形表面上的金属涂层厚度。 它非常适合测量微小的厚度，但对于小于 0.01 µm 的厚度，表面平整度和表面光滑度非常关键，因此，该方法不适合用于通常的最低测量水平。 电子手写笔仪器。 该方法适用于制备涂层厚度参考标准时测量涂层厚度。 [外文原描述]： This document specifies a method for the measurement of metal coating thickness by first forming a step between the surface of the coating and the surface of its substrate and then measuring the step height using a profile recording instrument. It covers the instrumentation characteristics and the procedure appropriate to this specific application of profilometric methods. The method is applicable to the measurement of thicknesses of metal coatings from 0,01 µm to 1 000 µm on flat surfaces and, if appropriate precautions are taken, on cylindrical surfaces. It is highly suitable for the measurement of minute thicknesses but, for thicknesses of less than 0,01 µm, surface flatness and surface smoothness are very critical and, accordingly, the method is not suitable for use down to the lowest level of measurement usual for electronic stylus instruments. The method is suitable for measuring coating thicknesses when preparing coating thickness reference standards.
