Vacuum electroplating vacuum coating and spraying process

Vacuum electroplating vacuum coating and spraying process

 

Titanium plating process includes: vacuum coating and spraying process.

 

Vacuum coating includes: magnetron sputtering, arc ion plating, etc. If nitrogen is introduced into the coating process to form titanium nitride, the coating color is golden yellow, otherwise white. In this method, the coating is thin, generally about 15 microns, and the coating is bright and does not require subsequent processing.

 

The method of spraying is cold spraying. The coating is very thick and can reach the order of millimeters, and the surface roughness requires subsequent processing.

Vacuum plating generally covers the background color for more than 90 seconds

 

Organic gases are generally used to adjust the red positive a value! But at the same time, it will slightly reduce the nitrogen effect! As for the time, generally more than 90 seconds will cover the background color

 

Process technology: After replacing the target material and changing the reaction gas, the following color and luster decoration coatings can be carried out on stainless steel and stainless iron plates, pipes and decoration hardware.

 

Titanium plating is generally used to improve the surface wear resistance of objects. For example, taps and drills used in high-speed machining centers can be titanium-plated to improve the wear resistance of tools, and the surface treatment of piston rings is also titanium-plated. Abrasion resistance.

 

There are also decorative titanium-plated rings. It is not as good as the similar gold rings that can be bought on the street for a few dollars. They are generally titanium-plated. The main color is golden yellow, beautiful, and avoids oxidation and rust on the surface of the object.

Argon as working gas for vacuum plating

1. When plating metal films, argon is generally used as the working gas. It is an inert gas and will not produce oxidation when the substrate is heated in a vacuum state. Generally speaking, argon is used to adjust the pressure of the furnace body, and the effect on color is not obvious!

 

2. Oxygen is generally used to coat non-metallic films, such as TiO2, so there is no need to worry about film oxidation after coating.

 

3. Nitrogen is the gas that is rushed into the vacuum chamber when the target is replaced and coated, so that the pressure in the vacuum chamber and the atmospheric pressure are kept equal, so that the cover can be opened and the target can be coated with another layer of film.
