Problems solved by technology

[0003] However, the above-mentioned manufacturing process can only improve the anti-corrosion performance of stainless steel, and does not propose a technical solution to solve the shortcomings of poor wear resistance and easy scratches of metal materials. The layer is relatively thin, generally 0.3~3 microns, therefore, the effect of increasing the thickness and hardness of the metal material is not obvious, and the metal material after coating still has the disadvantage of low wear resistance

Abstract

The invention belongs to the technical field of metal surface treatment, and especially relates to a metal surface treatment process which comprises the following process steps of: (a) surface cleaning, that is, performing surface cleaning of a metal substrate to be treated, removing attachments on the surface of the metal substrate; (b) glaze layer spraying, that is, performing atomization spraying of glaze onto the surface of the metal substrate by a spray gun or a sprayer to form a glaze layer; (c) baking and curing, that is, baking the metal substrate with the sprayed glaze layer in a baking oven so as to cure the glaze layer; (d) secondary cleaning, that is, performing secondary cleaning of the metal substrate with the sprayed glaze layer; (e) PVD coating, that is, performing PVD coating of the metal substrate with the sprayed glaze layer to form a film layer on the surface of the glaze layer so as to obtain the metal substrate finished product. The metal substrate finished product of the invention has high thickness and hardness, and thus has strong wear resistance and scratching resistance; the PVD coating provides the metal substrate finished product with good temperature change resistance and corrosion resistance, and good metal luster.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, in particular to a metal surface treatment process. Background technique [0002] In the prior art, metal materials such as stainless steel, copper, iron, aluminum, etc. have the disadvantages of poor wear resistance, prone to scratches, and poor corrosion resistance. In order to improve various properties of metal materials, people often carry out coating treatment on the surface of metal materials. For example, the Chinese invention patent application with the application number 200910102234.6 discloses a manufacturing process for improving the anticorrosion performance of 430 stainless steel plates, which adopts steps in sequence: Kaiping material preparation, grinding and polishing, cleaning, drying, inspection, PVD vacuum coating, and film packaging; The PVD vacuum coating process is as follows: (A), load the 430 stainless steel mirror plate in the vacuum furnace body, and v...
