Electrolytic degreasing in electroplating production is a pretreatment process that utilizes an electrolytic process to remove grease 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 degreasing 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:
Oil removal is an indispensable step in the plating process and is the key to ensuring good adhesion and surface finish of the electroplating. This article will elaborate on the importance of electroplating oil removal, and introduce the basic concepts of electroplating pretreatment.
Blackening of nickel plated workpieces in air is not usually a normal phenomenon, and may be caused by oxidation or sulfidation of the nickel plated surface. Nickel plating usually has good corrosion and oxidation resistance, but under certain circumstances, such as insufficient quality of plating, presence of contaminants in the environment, high humidity, or poor storage conditions, the surface of nickel plated parts may become discolored or blackened.
