Application of electroplating

With the development of social economy, the demand for electroplating is increasing, from a small pin to the space shuttle, all need to be plated to indicate treatment. Hardware, sanitary facilities, living facilities, metal products, etc. are inseparable from electroplating. Electroplating has been widely used in various fields such as anti-corrosion, protection, decoration, and building materials.

 Electroplating is a surface treatment technology that uses electrolysis to plating a thin layer of other metals or alloys on the surface of certain metals to form a metal coating. There are different effects depending on the plating requirements. Electro-galvanization is widely used for the protection of steel parts and structural parts because of its low zero, non-abrasive, low hazard of zinc ions to human body and good elasticity. The surface with hot dip galvanizing is very strong for corrosion protection, the shortcoming is that the price is relatively very high. Electroplated cadmium with its soft texture, good plasticity, less hydrogen embrittlement, good brazing performance is widely used in the aviation and marine and electronic industry parts. Copper plating is widely used in the protection of steel workpieces because of its good ductility, excellent processing performance and strong electrical conductivity. Electroplated nickel is generally used in combination with chromium plating, because of its high hardness and good wear resistance, it is widely used in radiators, chemical equipment, microelectronic components, etc. Nickel plating is commonly used as protection for medical instruments and household daily necessities. Chrome plating is characterized by good decoration, protection, corrosion resistance and high hardness, and is widely used in automobiles, bicycles, home appliances, hardware and other fields. Also, it is used as surface film layer of solar absorber, aviation and optical instrument parts, etc. Electroplated tin is characterized by good brazing performance, soft texture, good plasticity, and low friction coefficient without interaction with sulfide, so it is widely used in food canning boxes. In addition, electroplating is also used in a variety of composite plating. For example, graphite chloride composite plating used for electrical connectors to replace pure gold plating can greatly reduce the plugging force and extend the service life. Aluminum powder containing composite zinc plating in the polymeric zinc salt spray test shows that the corrosion resistance of pure zinc plating 6.2 times. Plating Fe-Ni5Cr with particulate composition of the composite coating. After heat treatment, chromium-nickel stainless steel can be obtained, etc.. The development of science and technology has led to a finer division of labor in industry, while the application of electroplating has become more and more widespread. As a basic industry, electroplating has been closely related to our life and is inseparable.
