Description

Technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a scaffold composite electroplating solution with good decorative effects. Background technique [0002] Electroplating, also known as metal electrodeposition technology, is the process of immersing the workpiece in a solution containing the metal salt to be deposited, applying a negative charge to the workpiece, and depositing a layer of metal or alloy layer that is tightly bound to the workpiece on the surface of the workpiece. The basic principle of electroplating is to cause metal ions in the solution to undergo a reduction reaction on the interface between the solution and the plated part through various electric fields, to generate metal atoms and deposit on the metal surface to form a coating. The composite coating is a surface modification technology in which insoluble solid particles are added to the plating solution to co-deposit the matrix metal and the sol...

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
