Abstract: Abstract: Chromium carbon coatings were electroplated from trivalent chromium chloride based electrolyte at
different complex agents such as HCOONH4, HCOONa and Glycine. The effects of different complex
agents on morphology, chemical composition, contact angle, ICR values and corrosion resistance of
coatings were investigated. All the electroplated conditions indicated that the carbon content within
chromium carbon coatings decreased with an increase of current density due to the chelation strength
of complexing agents in the bath collapsed by a higher drive force (higher current density). Results
also presented that the chromium carbon coatings electroplated from “HCOONa” will form granular
structure with an increase of current density, and leading to a poor ICR values. Both coatings
electrodeposited from “HCOONH4” and “Glycine” has better contact angle (about 105 and 112º) and
ICR values (<20 mΩcm2at 160 N cm-2), but the “Glycine” has a poor corrosion resistance. In this
study, chromium carbon coatings electroplated from“HCOONH4” have better contact angle (105º),
ICR values (<20 mΩcm2at 160 N cm-2) and corrosion resistance (3.90×10-7 A/cm2), and has high application
potential in bipolar plates.
