Steel plate electroplating process of Zn-Co-W alloy

Abstract

The invention belongs to the technical field of surface treatment, and particularly relates to a steel plate electroplating process of a Zn-Co-W alloy. The process comprises the steps of S1, steel plate pretreatment: the surface of a Zn-Co-W alloy steel plate to be electroplated is polished, cleaned and deoiled, and then the steel plate is subjected to anodic electrolytic polishing treatment; S2,steel plate electroplating treatment: the Zn-Co-W alloy steel plate treated in the step S1 is put into an electroplating device as a cathode, and electroplating is conducted by using a direct-currentpower supply; and S3, steel plate post-treatment: after treatment in the step S2 is completed, the electroplated Zn-Co-W alloy steel plate is put into a post-treatment furnace to be subjected to heattreatment, after treatment is completed, the temperature is naturally reduced to the room temperature, and a finished product of the electroplated Zn-Co-W alloy steel plate is obtained. The steel plate electroplating process of the Zn-Co-W alloy is low in cost and easy to operate, and an obtained coating is good in performance and more attractive.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, in particular to a Zn-Co-W alloy steel plate electroplating process. Background technique [0002] With the development of society, people's pursuit of product appearance is getting higher and higher, and tends to be more diversified. The appearance of products will directly affect the market competitiveness. Therefore, product appearance decoration is getting more and more attention. Zinc-cobalt-tungsten alloy has excellent performance. By electroplating the surface of the alloy steel plate, the performance of the steel plate and the appearance of the steel plate can be further improved, and the appearance of products made of zinc-cobalt-tungsten alloy can be improved to increase the attractiveness of consumers. force.

[0003] There are also some technical solutions in the prior art, such as the Chinese patent with application number CN201910975528.3, which includes the following steps: S1, cleaning and degreasing the product to be electroplated; S2, acidifying the product to be electroplated after cleaning and degreasing. Washing; S3, the first electroplating; S4, spraying a liquid protective film on the surface of the product; S5, engraving patterns on the surface of the product with radium, and carving off the protective film and the electroplating layer of the first electroplating; S6, the second electroplating, the second The process of the second electroplating is different from the first electroplating; S7, the PET protective film is torn off, and the product presents two electroplating effects; in the process of electroplating the product in this scheme, the coating obtained by electroplating on the product is not considered The quality of the obtained coating may be insufficient in the bonding strength between the coating and the product, which will affect the service life of the coating. Unevenness affects the coating effect of the product after electroplating. At the same time, during use, the coating is easy to peel off at the loose place, resulting in damage to the coating and affecting the aesthetics of the product.
