摘要

Chromium oxide (Cr_2O_3) films were deposited on stainless steel substrate by arc ion plating (AIP) technique. The results show that the flow rate of oxygen and bias voltage affected the microstructure, surface morphology and chemical composition of Cr_2O_3 films. The hardness of stoichiometric Cr_2O_3 film obtained at flow oxygen rate of 130 sccm and a bias voltage of -200 V reaches a maximum value of 36 GPa, much higher than that of films obtained by other deposition methods.
