Brush plating is a process that uses electrolysis to obtain a coating on the surface of a workpiece. Among them, it is to strengthen and improve the surface properties of the workpiece to obtain the decorative appearance, corrosion resistance, wear resistance and special optical, electrical, magnetic and thermal properties of the workpiece; it can also change the size of the workpiece, improve mechanical coordination, and repair defects caused by excessive tolerance or wear. And scrapped workpieces, etc., therefore have a wide range of applications in industry.

Electric brush plating technology has a series of unique advantages, mainly as follows: (1) The brush plating layer has good bonding strength, mechanical properties and physical and chemical properties. The bonding strength ratio between the brush plating layer and the substrate The tank plating and spray coating should be high, generally >70Mpa. (2) There are many types of brush plating coatings, and coatings with different performance requirements can be obtained, such as wear-resistant coatings, corrosion-resistant coatings, anti-wear coatings, conductive coatings, magnetic conductive coatings, high-temperature oxidation-resistant coatings, etc., and have anti-nitriding properties , prevent carburization and improve brazing properties and other special functions. (3) The quality of brush plating is high. The temperature rise of the workpiece during the brush plating process is <70°C, so it will not cause deformation of the workpiece, changes in the surface metallographic structure, and generate residual stress. (4) The ampere hour meter on the brush plating power supply can be used to accurately control the thickness of the deposited coating, with an accuracy of ±10%. In situations with low requirements (such as transitions and interference fits), it can be used without machining. Get the final surface for use. The coaxiality is high. Since the workpiece is electroplated while rotating, the direction of the coating around the circle is basically the same and no ovality will occur. (5) Brush plating technology has an extremely wide scope of application. It can be brush plated on various metal surfaces and even conductive non-metallic surfaces; it can be applied on various sizes and shapes (outer circles, inner holes, planes, curved surfaces, etc.) ) is brush plated on the surface. (6) Portability, brush plating is similar to an arc welder, and the equipment can be easily brought to the place where plating is to be performed, achieving on-site brush plating and non-disassembly brush plating. (7) The production efficiency is high, the deposition speed of brush plating is 10 to 15 times that of general tank plating, and there are few auxiliary processes and time. (8) Safe operation and little environmental pollution. The brush plating process causes little environmental pollution. The solution does not contain cyanide and other highly toxic substances. The solution can be recycled, consumes less, and does not cause a large amount of waste liquid discharge.
