The mortal flaw is: chromium containing waste water and waste serious carcinogenic, belongs to the state for a class of control emissions, and has great harm to the environment and the production workers. The other defects of gas spring chrome plating mainly include: (1) the cathode current efficiency is very low, generally only 18%~20%, plating speed is quite slow, the energy consumption is also very large.
