The coating thickness of the material is an important process parameter. It directly affects the corrosion resistance, decorative effect, electrical conductivity, product reliability and service life of parts or products. Therefore, the thickness of the coating plays an important role in product quality, process control, and cost control.

What is plating/coating?

Plating refers to coating a layer of organic matter, or a thin layer of metal or imitating some kind of precious metal, on the metal surface of some items for good-looking or storage, and plating this precious metal on the surface of ordinary metal. . The preparation of composite coating is a process of adding one or several insoluble solid particles to the plating solution to co-deposit the solid particles and metal ions. It is actually a metal-based composite material.

What is the coating thickness test? What are the methods?

Coating thickness test detects the thickness of metal and oxide coatings on the surface of the material. The measurement methods of coating thickness mainly include metallographic method, X-ray fluorescence method and scanning electron microscope measurement method and so on.

XRF coating thickness gauges are commonly known as X-ray fluorescence thickness gauges, coating thickness gauges, film thickness gauges, film thickness testers, gold-nickel thickness testers, electroplating film thickness gauges, etc. They are mainly used to accurately measure the thickness of metal electroplating layers.

XRF coating thickness gauge:

Commonly known as X-ray fluorescence thickness gauge, coating thickness gauge, film thickness gauge, film thickness tester, gold nickel thickness tester, electroplating film thickness gauge, etc.;

Function: precise measurement of the thickness of the metal plating layer;

Application range: measuring the thickness or composition of coatings, coatings, films, liquids, measuring range from 12 (Mg) to 92 (U)

The non-contact thickness measuring device using X-rays can allow the amount of quantum X-rays penetrating the target object to be detected by the detector, or the amount of fluorescent X-rays penetrating the target object to be detected to measure the thickness of the target object. The amount of quantum X-rays or fluorescent X-rays detected by the detector in response to the material of the target object varies in absorption coefficient, density, and thickness. It is not necessary to compare the amount of quantum X-rays of the target object and the amount of X-rays irradiated to pass through the target object and emitted from the X-ray target. thickness.

The calibration curve is determined by comparing the difference between the intensity of the signal scattered by the specific element in the base layer of the reference sample having the base layer and the base layer formed by the thin film layer formed thereon with the thickness of the thin film layer, and The target is determined by comparing the intensity difference between the signal scattered by a specific element in the base layer of the reference sample having the base layer and the base layer of the target sample having the base layer formed thereon with the calibration curve. The thickness of the film layer of the sample
