Embodiment 1

[0034] As the physical vapor deposition method of the first embodiment of the present invention, it specifically includes the following steps:

[0035] Base material pretreatment steps:

[0036] The present invention selects copper alloy as the base material, and first grinds and polishes the copper alloy through a grinding wheel, the grain size number of the grinding wheel is 180#, and then uses a cloth wheel to clear the light to obtain a base material with a surface finish Ra of 0.04;

[0037] Electroplating the copper alloy after the finish treatment to obtain a copper alloy covered with an electroplating layer, the electroplating layer is a nickel layer and a chromium layer, wherein the thickness of the nickel layer is 14 um, and the thickness of the chromium layer is 0.25 um.

[0038] PVD steps:

[0039] Soaking: Soak the pre-treated copper alloy base material in alcohol, take it out and wipe it with pure cotton cloth, and then hang it in a special hanger.

Abstract

The invention discloses a method for depositing a coating. The method comprises the steps of pretreating a base body material and performing physical vapor deposition (PVD), wherein in the PVD step, during deposition of a colorful layer, the composition and the structure of the colorful coating can be changed finely by controlling flow of reaction gas, so that the color of the obtained coating can be controlled accurately, and the increasingly improved visual demand can be meet.

Description

technical field [0001] The invention relates to a coating deposition method, which belongs to the technical field of surface treatment. Background technique [0002] Physical vapor deposition technology has been used in some applications as early as the beginning of the 20th century, but it has developed rapidly in the last 30 years and has become a new technology with broad application prospects, and is developing towards an environmentally friendly and clean trend. [0003] Physical vapor deposition (Physical vapor Deposition, PVD) technology refers to the use of physical methods to vaporize the solid or liquid surface of the material source into gaseous atoms, molecules or parts into ions under vacuum conditions, and through a low-pressure gas (or plasma) process , the technology of depositing a thin film with a certain special function on the surface of the substrate. The main methods of physical vapor deposition are vacuum evaporation, sputtering coating, arc plasma p...
