Description

technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a composite electroplating solution for electric corrosion-resistant scaffolding. Background technique [0002] Electroplating, also known as metal electrodeposition technology, is a process in which the workpiece is immersed in a solution containing the metal salt to be deposited, and a negative charge is applied to the workpiece to deposit a layer of metal or alloy layer that is closely bonded to the workpiece on the surface of the workpiece. The basic principle of electroplating is to reduce the metal ions in the solution on the interface between the solution and the plated parts through the action of various electric fields, generate metal atoms and deposit them on the metal surface to form a coating. Composite coating is a surface modification technology that adds insoluble solid particles to the plating solution to cause co-deposition of matrix metal and so...

Problems solved by technology

[0003] In the article "Research on NI-PTFE Composite Electroplating Process", the author proposed that the Ni / PTFE composite coating was successfully prepared by adding polytetrafluoroethylene emulsion and FC134 cationic surfactant to the electroplating solution. In terms of mechanical properties, the friction coefficient of the composite coating is 0.218, which is only about 34% of the pure nickel coating. However, due to the softness of PTFE, after entering the coating, the hardness of the composite coating is reduced compared with that of the pure nickel coating, and at the same time, the amount of wear is somewhat reduced.

Therefore, in some fields, this composite coating cannot meet the demand
