Cr-Fe-ZrO2 composite coatings were electrodeposited in trivalent chromium chloride electrolyte containing glycine as complexing agent. The effects of electrodeposition parameters such as current density and electroplating time on appearance, surface morphology and composition of the Cr-Fe-ZrO2 composite coatings were investigated mainly. The obtained Cr-Fe-ZrO2 composite coatings were characterized by means of scanning electron microscope (SEM) and energy disperse spectroscopy (EDS) techniques; the appearance quality was evaluated by range estimation; and the bonding force was analyzed by bending tests. The SEM results showed that the nano-size ZrO2 powder were fairly distributed through out in the composite coating, and the composite coating contained only few fine cracks. The EDS results indicated that the composite coating contained chromium, iron, zirconium, oxygen, carbon and chlorine. The deposited coating was glossy and the results of bending tests showed that the bonding between the composite coating and the substrate was good
