Effects of vacuum plating additives:

Effects of vacuum plating additives:

1. Leveling effect. It can be that the micro-rough surface of the substrate becomes flat and the roughness is reduced.

2. Wetting effect. It can reduce the interfacial tension between the metal and the solution, so that the coating and the substrate can be better attached, so that the hydrogen bubbles separated on the cathode can be easily detached, and pinholes are prevented.

3. Refine grains. It can change the crystallization state of the coating, refine the grains and make the coating finer. If no additives are added to the zincate galvanizing solution, a sponge-like deposit will be obtained. After adding the additives, the coating will be fine, detailed and bright.

4. Bright light effect. It is an indispensable ingredient for decorative electroplating by adding brightener and cooperating with other additives to further improve the brightness of the coating.

The additives used in pvd vacuum coating processing have many other effects, such as improving the hardness of the coating and reducing the stress of the coating. Additives should be selected and used. Some additives have several effects. Generally, (1-2) kinds of additives are contained in the plating solution. The additives currently used are mainly organic compounds or synthetics, and inorganic compounds are also used in combination.
