In recent years, the automotive industry has developed rapidly. As the foundation for supporting the rapid and stable development of the automotive industry, the development of China's automotive parts industry is of great significance, and electroplating technology is a commonly used technology to ensure the quality of automotive parts. Usually, electroplating treatment is carried out on the surface of automotive components to improve the reliability, stability, and corrosion resistance of automotive component materials during long-term operation.However,If the plating layer is too thick, it will increase the cost; Too thin to meet the product application quality requirements. Therefore, controlling the thickness of the electroplating layer is particularly important.

Case 1:

Zirconia is a commonly used protective film in the automotive industry, which utilizeshandheldelementThe analyzer filter membrane mode analyzes the thickness of zirconia coating on iron-based substrates, and the linear correlation between various data points is very good, almost on the same straight line. The optimized test data is shown in the table below, and the relative error between the test results and the standard values is less than 3%.

Case 2:

High voltage isolating switches are widely used in the power industry, mainly for electrical isolation between high-voltage lines and electrical equipment such as no-load switching and circuit breakers. For high-voltage isolating switches that are exposed to atmospheric environmental conditions year-rounduseThe equipment is usually plated with a layer of silver on the surface to maintain good conductivity of the switch, and the thickness of the coating greatly affects the conductivity and service life of the switch.

利用handheldThe thickness measurement mode of the elemental analyzer, analyze onebeThe results of listing copper silver plated samples are shown in the table below. Each data pointThe correlation coefficient is 0.996,The linear correlation is very goodWhen the thickness of silver isWithin the range of 1-30 µ m, measured value and nominal valueThe average error is 0.6 µ m, and the average error within the range of 30-60 µ m is 1.3 µ mThe relative error is less than 4%, which is within an acceptable range,Thickness measurement rangereachable1-60 µm。

At present,SeppusHandheld Spectral Analyzer (HHXRF)The plating mode can be analyzedMulti layer coating material, the substrate can be any type of material, not limited to metal.Therefore, in industries such as automobile manufacturing, aerospace, and power, thin film thickness measurement is requiredHas enormous application prospects.
