NNX-D43 21X10 ET 33 P.C.D 5X112 center hole 66.6 1piece forged wheel (custom 16-24inch and date) Repair for stainless steel forging   Forging electroplating is the process of applying the basic principle of electrochemical chemistry. In the electrolyte, forging is used as cathode, metal is anode, and a solid coating is deposited on the surface of the forged surface by DC. Forging should be subtracted, rust and activated before electroplating, and purification treatment can be performed after electroplating.   Chromium plating is widely used in the surface reinforcement technology of forging. The hardness of the chrome layer is 900 to 1200HV, which can effectively improve the abrasion resistance of forging, which will not cause the forging deformation, which is conducive to the surface reinforcement of complicated forging. The coating is generally 0.030.30 mm .. This process is only applicable to small stretch molds and plastic molds.   Remove the fatigue cracks of the general parts of repairing forging with pneumatic sandwheels. After the deep angle is removed with an arc, it can be processed by a depth of 10mm in the repair site with a depth of 10mm, and then the surface is cleaned. To prevent the pile welding from cracking, the pile welding forging should be preheated (450 ~ 500 C), slowly cool down after pile welding to prevent cracking, and then immediately ignite it. At this time, the hardness of the pile welding part is much higher than the mold.   Mold pile welding technology can enable the forging to obtain the ideal comprehensive performance, reduce re -manufacturing costs, and extend the service life. Generally, 506,000 pieces can be scrapped by forging through edge and mold cutting. The service life of the use can be increased by 12 times after pile welding. The service life of the thermal forging model can be more than doubled and can be repaired multiple times.
