The roughness of the nickel plated layer is closely related to the nickel plating brightener used. Brightener is a chemical additive added to the plating solution, and its main function is to improve the gloss and flatness of the plated surface. The following points explain the effect of nickel plating brighteners on the roughness of the nickel plated layer:
In the electroplating industry, proper control of additives in nickel baths, especially nickel plating softeners, is crucial to ensure the quality of the nickel layer. A moderate amount of additives can optimize the brightness and toughness of the nickel layer, however, an excessive amount of softener can lead to a series of problems, such as increased brittleness and stress concentration of the nickel layer, and can even cause cosmetic defects and decreased adhesion. As a result, determining whether the amount of softener in the nickel plating bath is appropriate becomes a critical step in the plating process.
During the plating degreasing process, it is important to properly clean grease and dirt from the workpiece, especially from inside the blind holes, as this ensures uniformity, adhesion and overall quality of the plated layer. Here are some suggestions for cleaning blind holes in plated parts:
The reason for using hydrochloric acid for plating rust removal is that hydrochloric acid is effective in removing oxidized layers, rust, and other contaminants from metal surfaces. Metal surfaces can easily form a layer of iron oxide, or rust, after prolonged exposure to air. These oxides must be thoroughly cleaned before plating to ensure that the plating layer adheres evenly and firmly to the metal surface.
Zinc alloy die casting is easy to blister, which is a problem for many electroplating factories, because it is related to the straight-through rate of electroplating products, and will affect whether die-casting factory customers will continue to choose them. Therefore, it is very urgent to solve this problem. In this article, we will analyze the importance of pre-treatment wax and oil removal process for improving the binding force of zinc alloy coating.
Electrolytic oil removal in electroplating production is a pretreatment process that utilizes an electrolytic process to remove oil and organic contaminants from the surface of metal workpieces. Cleaning the metal surface prior to plating is critical, as oil and grease can hinder the uniform deposition of the plating layer and may lead to quality problems such as peeling and flaking of the plating layer. Electrolytic oil removal powder is a chemical agent used in industrial production to remove grease and other impurities from metal surfaces, mainly by electrolysis. The following factors should be considered when selecting a suitable electrolytic degreasing powder:
