Electroplating and PVD

Electrowinning refers to electrolytic deposition. Electrolysis uses current to dissolve to achieve the purpose of extracting metals or substances. Deposition is a process in which metals or substances are precipitated from a purification solution. It is an important process in hydrometallurgy. It is widely used in metallurgical refining.

PVD is a physical deposition. PVD technology is the most popular vacuum coating and plating method. The typical PVD coating process is maintained at a temperature between 250 and 500. The specific requirements are based on the actual needs of the product and the process of the film. 100 can also be higher than 600 degrees Celsius. The coating types of general products are TiN, TiC, TiCN, TiAlN, TiAlCN, TiCrN, TiCrCN, TiAlCrN, TiALYN and the like. The thickness of the film is 2~5um, which can be thickened or thinned.

Electroplating is divided into water plating physical plating. Water plating is a popular coating method. It is seriously polluted and is gradually replaced by physical plating (ie, vacuum plating). There are many types of plating: hanging plating, barrel plating, brush plating, Continuous plating, etc., depends on the plated product. Plating principle
