Problems solved by technology

The strength of metal bonding depends on the crystal lattice and crystal plane properties of the two interfaces, while the bonding strength of the coating mainly depends on the bonding strength, which leads to the disadvantages of low bonding strength and easy peeling off of brush-plated coatings.

Abstract

The invention discloses a treatment method for improving bonding strength of an electric brush plating coating layer. A part after electric brush plating is put in a container of -85--75 DEG C; the container is put in a low-frequency compound pulse magnetic field; and current is intermittently applied to the container put in the low-frequency compound pulse magnetic field for treating the part after electric brush plating. The treatment method for improving bonding strength of the electric brush plating coating layer is simple in process and convenient for operation, and can improve the bonding strength of the electric brush plating coating layer and a matrix.

Description

technical field [0001] The invention relates to a treatment method for improving the bonding strength of an electric brush plating coating. Background technique [0002] Brush plating is the process of obtaining a coating on the surface of a workpiece by electrolysis. It is mainly used to improve and strengthen the surface properties of metal material workpieces, so that it can obtain one or more of the aspects of wear resistance, corrosion resistance, oxidation resistance, and high temperature resistance. performance. In terms of mechanical repair and maintenance, brush plating is widely used to repair mechanical parts that are scrapped due to metal surface wear failure, fatigue failure, and corrosion failure, and restore their original dimensional accuracy. It has the characteristics of long service life of the final mechanical parts, especially for the repair of large and expensive mechanical parts, and the economic benefits are more significant. There is no deformation...
