1.前言复合材料具有优良的综合性能,所以其研究和生产发展极为迅速。就贵金属复材而言,常用复合方式有电镀复合,层状复合、纤维复合、弥散复合等。前两种复材的研究和生产应用中,如何准确测量复层的厚度是很重要的。因为复材的许多性能与它有关。一般金属电镀层的厚度为零点几微米到几十微米。根据不同镀层材料及厚度,常用β射线反向散射原理、X 射线分光计、显微法、计时液流法、点滴法、溶解法等测
1. Introduction Composite materials with excellent overall performance, so its research and production development is extremely rapid. In terms of precious metal complex, the commonly used composite methods are electroplating composite, layered composite, fiber composite, dispersion composite. In the first two kinds of complex research and production applications, how to accurately measure the thickness of the cladding is very important. Because of the many properties of the complex material related to it. General metal plating thickness of a few tenths of a few microns to tens of microns. According to different coating materials and thickness, commonly used β-ray backscattering theory, X-ray spectrometer, microscopy, timing flow method, drip method, dissolution method, etc.
