PVD color coated stainless steel process production process

Stainless steel vacuum color plating process also called PVD color coating is a commonly used surface treatment technology, which is used to form a color coating on the surface of stainless steel materials.

The following is the general stainless steel vacuum plating process production process:

Surface preparation:

First, thoroughly clean the stainless steel material to remove dirt, grease and oxides from the surface. Common cleaning methods include pickling, mechanical polishing, and sandblasting.

Loading items:

Place the prepared stainless steel material in the working chamber of the vacuum coating equipment to ensure that there are no obvious defects and pollutants on the surface.

Vacuum pumping:

Start the vacuum equipment to pump out the gas in the working room to create a high vacuum environment. This helps to improve the quality and uniformity of the coating.

Pretreatment:

Pretreatment steps are performed in a vacuum environment to increase the adhesion between the coating and the substrate. Pretreatment methods include surface activation, chemical treatment, and sputter cleaning.

Coating:

According to the required color and effect, different materials are used for coating. Common coating materials include metal nitrides, metal oxides, and metal sulfides. By controlling the deposited materials and process parameters, different color effects can be achieved.

Auxiliary treatment:

After the main coating, some auxiliary treatment steps such as annealing, polishing and cleaning can be carried out to improve the surface quality and finish.

Inspection and packaging:

Carry out quality inspection of coating products, including visual inspection, adhesion test and abrasion resistance test, etc. Qualified products are packaged and ready to leave the factory or deliver to customers.

It should be noted that the specific process may vary due to different equipment and materials.

In practical applications, it should be adjusted and optimized according to specific requirements and conditions.
