Plating is the process of depositing metal on the surface of parts using electrolysis to form a protective metal layer. Richconn can provide you with chrome plating, rhodium plating, nickel plating, zinc plating, copper plating, tin plating, cadmium plating, titanium plating, Aluminum plating services.
The purpose of plating is to improve the appearance of a material while imparting various physicochemical properties to the surface, such as corrosion resistance, decorative properties, abrasion resistance, brazing properties, as well as conductive, magnetic, and optical properties.

The zinc coating has high purity and is an anodic coating. The zinc layer plays a role in mechanical protection of the steel matrix and also plays an electrochemical protection role. Galvanized layer is widely used in machinery, hardware, electronics, instrumentation, light industry, etc., and is one of the most widely used plating types.
The copper plating layer is a cathodic plating layer, which can only provide mechanical protection to the base metal. The copper plating layer is usually not used as a protective decorative coating alone, but as the bottom or middle layer of the coating to improve the bonding strength between the surface coating and the base metal. It is used in the electronic field, such as copper plating through holes on printed circuit boards, as well as in hardware technology, handicrafts, furniture decoration and other fields.
The nickel plating layer is a cathodic protective layer and only provides mechanical protection to the base metal. In addition to direct use in some medical devices and battery casings, the nickel plating layer is often used as the bottom layer or intermediate layer and is widely used in daily hardware, light industry, home appliances, machinery and other industries.
The chromium plating layer is a cathodic plating layer and only plays a mechanical protection role. Decorative chrome plating, the bottom layer is usually a polished or electrodeposited bright coating.
It is widely used in exposed parts of instruments, meters, daily hardware, household appliances, airplanes, automobiles, motorcycles, bicycles, etc. Functional chrome plating includes hard chrome plating, porous chrome plating, black chrome, milky white chrome, etc.
Relative to the steel matrix, tin is a cathodic coating, while relative to the copper matrix, it is an anodic coating. The tin plating layer is mainly used in the can-making industry as a protective layer for thin plates. Most malleable iron sheets are made of tin-plated iron sheets. Another major use of tin plating is in the electronics and electrical industry.
In a solution, two or more metal ions co-precipitate on the cathode to form a uniform and fine coating, which is called alloy plating. Alloy electroplating is superior to single metal electroplating in terms of crystal density, coating porosity, appearance color, hardness, corrosion resistance, wear resistance, magnetic permeability, wear reduction and high temperature resistance. Widely used in aviation, aerospace, navigation, automobiles, mining, military industry, instruments, meters, general hardware, tableware, musical instruments and other industries.
