Abstract

The invention provides a preparation method of a plated film member, which comprises the following steps: providing a base material, wherein the base material is a transparent glass; using a sputtering method and forming a prefabricated layer A on the surface of the base material, wherein the prefabricated layer A is the alumina layer or aluminum nitride layer; continuously employing the sputtering method to form a prefabricated layer B on the surface of the prefabricated layer A, wherein the prefabricated layer B is aluminum layer, chromium layer or titanium layer; performing bombardment on the plated film surface of the base material by using argon plasma until the prefabricated layer B is completely stripped; repeating the above steps of plating the prefabricated layer B and argon plasma bombardment to form a color layer of the prefabricated layer A, wherein the color layer permeates the base material and the color layer presents white color. The preparation method of the plated film member enables stabilization, reliability and environmental protection. The invention also provides the plated film member prepared by the above method.

Description

technical field [0001] The invention relates to a method for preparing a coating piece and a coating piece prepared by the method. Background technique [0002] In order to make the casing of the electronic device rich in color, currently the decorative coating is mainly prepared by processes such as anodic oxidation, baking varnish, and porcelain baking. Compared with these traditional processes, PVD coating technology is more green and environmentally friendly, and the use of PVD coating technology can form a decorative color layer with a metallic texture on the surface of the product shell. [0003] However, in the prior art, the color of the film layer formed on the surface of the shell by PVD coating technology is very limited. Currently, the PVD film layers that can be widely prepared and used are mainly golden yellow, black, blue and other colors. White, as a classic color, is difficult to obtain through PVD coating technology in the industry at present, so using PVD...
