ACID PURIFICATION FOR CHROME
PLATING Chromic Acid Purification - Removing Contaminants for Consistent Bath Performance. In hard chrome
plating processes, metal contaminants (Al, Cu, Fe, Cr3+, etc.) buildup in the
plating bath,which lead to a decline in performance measured by longer
plating times, higher voltages, and an increase in
plating defects. Eventually, bath replacement becomes necessary and fresh chromic acid must be added, while old solution must be hauled off-site. Considerable...
