XRF fluorescent film thickness gauge coating thickness gauge EDX8000T PLUS application in metal coating qualitative and quantitative analysis

X-ray fluorescence spectrum (XRF) coating thickness gauge EDX8000B are widely used in coating in the qualitative and quantitative analysis, we test steps for the measurement and optimization of the method using a feature specific to each element of X ray to determine whether to deposit on the FP method is used to rapid determination of a group of some elements in different concentrations of electrolyte CLP sedimentary copper element in the coating Content, and the results show that this method can quickly change of element content in the coating, the method is testing, less investment, easy to master, speed, etc

X – RAY thickness gauge EDX8000T PLUS basic principle

X-Ray is widely used in all kinds of nondestructive testing. In addition to the common penetration inspection, can also by stimulating element characteristic fluorescence for element analysis. Learn how to elements through the characteristics of X-ray fluorescence analysis, please refer to the XRF (X-ray rayFluorescence) principle is introduced.

Film thickness is commonly used comparative analysis method

X ray film thickness analysis technology can measure the thickness of the multilayer material. But, this kind of analysis is likely to be multi-layer materials the influence of shadow, unable to see the signal, the base plate element also is unable to determine whether the X-ray has penetrated all the coating.

Taking the common nickel and gold plating on copper as an example, part of the nickel in the middle coating will be shielded by the top layer of gold plating, resulting in a smaller signal (count). The characteristic light signal of the copper substrate cannot penetrate the plating. Get the signal. In this case, how do you confirm that the X-ray source has actually penetrated the coating, rather than just measuring part of the coating thickness?
