Gold plating process for solving diffusion of selective gold plating area and improving gold plating function

Abstract

The invention discloses a gold plating process for solving diffusion of a selective gold plating area and improving a gold plating function, and belongs to the technical field of surface treatment solutions. The gold plating process comprises the steps that S1, preparing a gold plating solution, S2, preparing an auxiliary solution; S3, preparing a gold-plated product; S4, plating nickel; S5, coating the gold plating solution; and S6, performing a salt spray functional test. According to the gold plating process for solving the diffusion of the selective gold plating area and improving the gold plating function, the boundary line of a gold plating area region is clear, external invalid region diffusion is avoided, the functional test of a gold plating layer is improved, and the gold plating use amount cost is reduced; a developed special inhibitor additive is added into gold plating liquid medicine, so that the effective region after gold plating is regular and the boundary line is clear; through the salt spray functional test, the corrosion of a primary battery generated in the salt spray test is reduced due to the diffusion of the gold layer region, the salt spray test capability is improved, the product quality is improved, the diffusion of the gold layer in the ineffective area is solved due to the inhibitor additive, the usage amount of a noble metal gol is greatly reduced d, and the cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of surface treatment solutions, and in particular relates to a gold plating process which solves the problem of diffusion in selective gold plating areas and improves the gold plating function. Background technique [0002] In order to protect and decorate the surface of metal products, the surface of metal products is generally gold-plated with surface treatment potions. In the gold-plating process, the most important thing is the ratio of gold-plated potions. The process of plating a thin layer of other metals or alloys on the surface is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation. [0003] In the prior art, due to the lack of inhibitors in the gold-plating potion, after the surface treatment potion is partially gold-plated on the gold-plated area, due to the fluidity and ductility of the potion itself, the gold-...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the lack of inhibitors in the gold-plating potion, after the surface treatment potion is partially gold-plated in the gold-plated area, due to the fluidity and ductility of the potion itself, the gold-plating is easy to produce an overflow area on the surface of the product, affecting The surface area of ​​the gold-plated product is divided and displayed, which in turn affects the product aesthetics and wear resistance of the gold-plating process, and the lack of wear resistance of the product in the gold-plating process affects the follow-up wear resistance of the product, and a solution is proposed Gold-plating process to improve gold-plating function by diffusing permanent gold-plated area
