Various functional coatings are obtained on the surface of the parts by electroplating technology, and the functions of corrosion resistance and decoration are achieved by coating the surface of the parts without changing the characteristics of the material matrix. For a long time, electroplating technology has played an important role in the development of various industries in the national economy. Especially with the development of modern industry and technology, many product parts encounter very special environmental conditions during use, such as harsh corrosion, wear and friction environment, special pore requirements (circuit board), etc. The functionality of the electroplated layer on the surface of the component places higher demands on, for example, high corrosion resistance. Good resistance to high temperature oxidation, good electrical conductivity, high hardness, high wear resistance and friction reduction, uniformity of microfabrication and other special physical and chemical properties.
In addition, with the rapid development of the electronics industry, it is necessary to plate special electronic, magnetic, soldering, and thin film resistors on the surface of electronic components. Under the general trend of environmental protection and clean production, it is required to eliminate cyanide, chromate, lead and other pollution processes in traditional electroplating technology, and instead develop clean production electroplating processes (such as cyanide-free plating, chrome plating, Lead-free plating, etc.).
Although some dry coating technologies and powder coatings and organic coatings can partially replace the surface plating treatment technology of parts, most of these methods require complicated equipment conditions and large investment, and the organic coating has non-conductivity problems. Electroplating technology still has an irreplaceable role (such as the use of wet plating for multi-layer printed circuit board pore metallization). In the process of national economic development, the development and progress of other industries have also promoted the advancement of electroplating technology. Therefore, electroplating technology also needs to develop with the development of the national economy, the development of other industries, and the advancement of science and technology, so that it can be invincible.
