Characteristics and Applications
The cathode current efficiency is 20~26%, and the deposition speed is fast, which is 2~3 times that of traditional hard chrome plating. The hardness of the coating can be stable to more than 950HV; the number of microcracks is greater than 400/cm; The crystallization of the coating is fine and bright.
It is used for electroplating hard chrome in construction machinery, automobiles, motorcycles and other fields.
