Trivalent Chromium Plastic Electroplating
Trivalent Chromium Plating For Plastic Parts Cr3 Plating (Black Chromium Chrome)
Trivalent chromium and Black chromium is used for consideration of ecology. Deeper hue represents different hue from chromium plating.
Cherng Yi Hsing has invested in environmentally responsible surface finishing technologies and can provide a viable alternative solution to hexavalent chromium plating for decorative applications. The Cr3 Plating (Trivalent chrome) processes, purely based on Cr3, In some applications and at certain thicknesses, trivalent chromium plating can replace hexavalent chromium. This is especially true for decorative applications where the trivalent chromium finish can closely resemble the hexavalent chromium finish.
The trivalent chromium plating rate and hardness of the deposit is similar to hexavalent chromium plating. Trivalent chromium baths also operate in the same temperature ranges as hexavalent chromium baths. Generally, the range of plating thickness for trivalent chromium is 0.005 to 0.050 mils. Trivalent chromium baths tend to be more sensitive to metallic impurities than hexavalent chromium baths. Impurities can be removed by using ion exchange or precipitating agents followed by filtration.
