Measuring Elements of Coating Thickness Gauge
The covering layers we form for the surface protection and decoration of materials, such as coatings, platings, coatings, sticking layers, chemically formed films, etc., are called coatings or coatings in relevant national and international standards.
Coating and cladding measurement has become an important part of the quality inspection of the processing industry and surface engineering, and is an essential means for products to meet high quality standards. In order to make products internationalized, there are clear requirements and regulations on the measurement of coating thickness in my country's export commodities and foreign-related projects.
The coating thickness measurement methods mainly include: wedge-cut coating measurement, optical section coating measurement, electrolytic coating measurement, thickness difference measurement method, weighing method coating measurement, x-ray fluorescence method coating measurement, β-ray backscattering method coating measurement, capacitive coating measurement, magnetic measurement method and eddy current measurement method to measure thickness, etc. Among these methods, the first five are destructive testing, the measurement methods are cumbersome and slow, and most of them are suitable for sampling inspection. With the advancement of science and technology, especially in recent years, after the introduction of single-chip microcomputer technology in our unit, the MC-2000 series of magnetic measurement coatings and the MCW-2000B coating thickness gauge of eddy current method have taken a big step towards the direction of miniature, intelligent, multi-functional, high-precision and practical. The measurement resolution has reached 1 micron, and the accuracy can reach 1%, which has been greatly improved. The coating thickness gauge has wide application range, wide measuring range, easy operation and low price. It is the most widely used coating thickness gauge in industry and scientific research.
