Abstract

The invention provides a graphene-containing metal-matrix composite plating solution capable of improving the brushing electroplating coating quality by using the hydrogen absorption effect. The solution is prepared from a metal-matrix brushing electroplating solution and a graphene-containing dispersion solution which are mixed in the volume ratio being 1:1, wherein the concentration of graphene in the composite plating solution is 1-5 g / L. With the adoption of the graphene-containing metal-matrix composite plating solution, hydrogen produced in the brushing electroplating process is absorbed by the aid of the hydrogen absorption effect of the graphene, so that air holes of a coating are reduced, and the overall quality of the coating is improved. The graphene-containing dispersion solution is added to the metal-matrix brushing electroplating solution, a mixed plating solution is formed, and the graphene in the plating solution can solve the problem that a lot of air hole defects exist in the coating, so that the quality of the coating is improved.

Description

technical field [0001] The invention relates to a plating solution for brush plating, in particular to a metal-based composite brush plating solution containing graphene materials. Background technique [0002] Brush plating technology is produced to meet the needs of the actual production environment, and is the extension and development of electroplating technology. It has a series of advantages such as simple equipment, convenient operation, flexible process, high deposition efficiency, wide application range, various coating types, high bonding strength, low environmental pollution, water and electricity saving, and generally does not require mechanical processing after plating. It is a very effective method for repairing and strengthening mechanical parts. There is a huge disadvantage in the coating obtained by brush plating. There are many holes in the coating, which affects its overall wear resistance, corrosion resistance, high temperature resistance and other prope...
