[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 a composite electroplating solution with a good rust protection function for scaffolds. The composite electroplating solution is composed of, by weight, 6.8-9 parts of aniline, 0.1-0.2 part of ammonium persulfate, 50-60 parts of boric acid, 2-3 parts of sodium acetate, 220-250 parts of nickel sulfate, 40-50 parts of nickel chloride, 0.2-0.3 part of lauryl sodium sulfate, 50-60 parts of polytetrafluoroethylene emulsion, 3-4 parts of cationic surface active agents FC134, 2.2-3 parts of cerous nitrate, 1.4-1.8 parts of neodymium nitrate, 4.6-5 parts of aluminium nitride, an appropriate amount of concentrated ammonia water, an appropriate amount of absolute ethyl alcohol and an appropriate amount of deionized water. According to the electroplating solution, the electroplating technology is simple, the strength, the corrosion resistance, the toughness and the abrasive resistance of the scaffolds are improved, plating layers do not fall off easily, the cost is lowered, and the service life is long. Thus, the composite electroplating solution is worthy of popularization.
Description
technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a scaffold composite electroplating solution with good antirust function. 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 solid part...
