Abstract

The invention relates to the technical field of physical vapor deposition surface treatment, in particular to a method for preparing an anti-fingerprint black film on the basis of PVD and a film coated part. According to the method for preparing the anti-fingerprint black film on the basis of PVD, by depositing a film coating layer on the surface of a part to be plated through magnetron sputtering, a black layer with the high-end texture is obtained through a PVD film coating technology, so that heavy-pollution raw materials such as high-concentration acid-base and chromic acid in traditional water electroplating are replaced, and the problems of wastewater treatment and discharge are solved; and the film coating layer has an anti-fingerprint effect and is excellent in compactness and wear resistance. The method for preparing the anti-fingerprint black film on the basis of PVD has the advantages of no wastewater discharge, low cost, excellent performance and the like in the production process , and can be widely applied to the fields of hardware, household appliances, bathroom accessories, automobile accessories and the like.

Description

technical field [0001] The invention relates to the technical field of physical vapor deposition surface treatment, in particular to a PVD-based method for preparing an anti-fingerprint black film and a coating piece. Background technique [0002] Metal or plastic surface products need to enhance corrosion resistance, increase hardness, prevent wear, improve electrical conductivity, lubricity, heat resistance, and beautiful surface, and often require electroplating treatment. The electroplating process has been developed to the present, and it has become a very important processing technology at present, and it occupies a large proportion in protection and decoration. Especially in the electronic industry, communication and military industry, aerospace and other fields, a large number of functional electroplating technologies are used. Although the application of electroplating is very extensive, electroplating is also one of the three major polluting industries, and it wil...
