Embodiment Construction

[0031] The present invention will be described below in conjunction with specific embodiments.

[0032] A method for preparing a green coating by physical vapor deposition, comprising the following process steps, specifically:

[0033] a. Degreasing and cleaning:

[0034] a1. Place the product to be processed in a general degreasing and cleaning solution for soaking and cleaning;

[0035] a2. Put the product soaked and cleaned in the general degreasing cleaning agent in alcohol for ultrasonic cleaning treatment, and the time for ultrasonic cleaning treatment is 3-8 minutes;

[0036] a3. Put the product after ultrasonic cleaning treatment into ultrapure water for slow dehydration treatment, and the ultrapure water is 100°C hot water;

[0037] a4. Put the product after ultra-pure water dehydration treatment in an oven for baking. The oven uses 110-180°C circulating air for baking, and the baking time is 30-50 minutes; the product is placed in the oven After the middle baking ...

Abstract

The invention discloses a method for preparing a green coating by physical vapor deposition. The method comprises the steps of deoiling and cleaning, preparing a bottom layer, preparing a transition layer, preparing a harden and wear resistant film layer, preparing a color layer, and cooling and discharging, wherein the step of deoiling and cleaning comprises the following steps of soaking and cleaning with a general deoiling detergent solution, ultrasonic cleaning in alcohol, slowly drawing and dehydrating in ultra-pure water of 100 DEG C, and baking. Through the process step design, according to the method for preparing a green film on a product by physical vapor deposition, and compared with a coating deposited by a traditional method, the deposited coating has high corrosion resistanceand good oxidation resistance, so that the daily use of the product is met very well, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the technical field of PVD blue-green color technology, in particular to a method for preparing a blue-green coating by physical vapor deposition. Background technique [0002] At present, with the rapid development of various electronic products and fierce competition, consumers not only require high-quality and durable products, but also have a particularly strong demand for high-end fashion, colorful and eye-catching appearance. [0003] It should be further pointed out that for the traditional PVD blue-green process, it has the defects of low hardness, poor corrosion resistance, non-wear resistance, and poor process stability. Therefore, it is necessary to improve the existing PVD blue-green process. Contents of the invention [0004] The purpose of the present invention is to provide a method for preparing a green coating by physical vapor deposition in view of the deficiencies in the prior art, the green coating prepar...
