Attention to color stainless steel for vacuum plating

The vacuum electroplating color PVD film can improve the anticorrosion performance of the substrate surface, but it can not completely prevent the substrate from being eroded.

Therefore, the good anticorrosion performance of the substrate itself is the key to maintain the PVD film for a long time.

Because of the excellent anticorrosion performance of stainless steel, color PVD film is the best choice on the surface of stainless steel.

What problem should electroplating color stainless steel pay attention to specifically then?

 

I. matters needing attention before plating:

 

All stainless steel products must be cleaned before plating:

 

A. The stainless steel plate is easy to clean due to its uniform surface thickness, as long as the protective film and surface glue and impurities are removed;

In addition, some boards are placed too long, resulting in the deterioration of the protective film follow-up surface glue is difficult to remove, and affect the surface cleaning.

 

B. The cleaning and cleaning of the stainless steel components are relatively complicated. In addition to the obvious surface cleaning, the impurities such as polishing wax, glue, rust, dust, welding slag and other impurities should be removed with cleaning agent in some welding, folding, elbow and other non-obvious cracks.

For the stainless steel components to be plated, the biggest cleaning problem comes from some of the hidden in the stainless steel tube and visible in the polishing wax, salt, rosin, sand, wood, glue, plastic and other difficult to remove substances.

These substances will seriously affect the quality of vacuum coating, resulting in color abnormalities or fading, so the stainless steel component manufacturers in the production process should try to avoid the above substances hidden in the component and can not be removed, so as not to affect the subsequent vacuum plating color stainless steel coating quality
