Before plating processing needs to do what work?

Electroplating pretreatment affects plating effect, countless proved that if there is oil or rust metal surface such as non-metallic substances, although when the coating can be deposited, but because of oil "Molybdenum plate" level of the plating layer formation, adhesion strength, corrosion-resistant is affected, even deposition is not continuous, osteoporosis, and even coating flaking, so the loss of the actual use value. Therefore, before plating process to become an important process operation. Before plating processing needs to do what work it? Here PHNIX plating heat pump simply summarize for you.
Before plating treatment, called before processing (pretreatment), do need to do the following pre-treatment:
1, Wash: Removal of the metal surface of the oil, fat, abrasives, and sludge. Available jet wash, solvent wash, wash or electrolytic immersion wash.
2, cleaning: Wash with cold or hot water during the cleaning agent residue or dirt. 3, acid leaching: go to rust dirt or other oxide film, pay attention to prevent the substrate from corrosion or hydrogen embrittlement. Inhibitors can be added in order to avoid excessive acid leaching. After acid leaching to adequately cleaned.4, activation: Promoting adherence of coating, can be used a variety of acid activation of the molybdenum plating surface.5 Rinse: immediately before the removal of acid plating film, and then plating.Applied to the electrodes or a part rack, so that the parts of the surface layer of non-conductive material.
46 wetting agent:
Parts can reduce the interfacial tension between the solution, the workpiece surface is easy to be wetted substances.
47 Additives:
Contained in the solution can be improved electrochemical performance or improve the quality of the solution a small amount of additives.
