Car Network Small dumbbells The chrome plating solution uses highly oxidizing chromic anhydride (CrO3) rather than chromium salts. Therefore, during the plating process, external ions need to be added to achieve the chromium deposition process. The cathode polarization process is complex. Experienced chrome plating workers can judge whether the chrome plating is normal by the amount of cathode “flowers”. This “flower” is the hydrogen released from the cathode. The current density used in chrome plating is very high,
