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

Abstract

The invention discloses corrosion-resistant scaffolding composite electroplate liquid. The corrosion-resistant scaffolding composite electroplate liquid comprises, by weight, 6.8-9 parts of aniline, 0.1-0.2 part of ammonium persulfate, 50-60 parts of boric acid, 220-250 parts of nickel sulfate, 40-50 parts of nickel chloride, 0.2-0.3 part of lauryl sodium sulfate, 0.6-0.8 part of sodium citrate, 50-60 parts of teflon emulsion, 3-4 parts of a cationic surface active agent FC134, 1.5-3 parts of lanthanum oxide, 20-30 parts of crylic acid, 0.1-0.3 part of cetyl trimethyl ammonium bromide, 0.1-0.2 part of a silane coupling agent kh550, a proper amount of ethyl alcohol and a proper amount of deionized water. The electroplate liquid prepared through the method is simple in technology and short in consumed time, a good coating can be formed on the surface of a plated piece, and binding force is good. Moreover, the abrasive resistance and corrosion resistance are greatly improved, and the corrosion-resistant scaffolding composite electroplate liquid is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a corrosion-resistant scaffold composite electroplating solution. 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 metal or alloy layer on the surface of the workpiece that is closely bonded to the workpiece. The basic principle of electroplating is that the metal ions in the solution undergo a reduction reaction at the interface between the solution and the plated part through the action of various electric fields to generate metal atoms and deposit them on the metal surface to form a coating. The composite coating is a surface modification technology that forms a composite coating by adding insoluble solid particles to the plating solution to co-depo...
