Abstract: <span style="mso-fareast-font-family:DFKai-SB" lang="EN-GB">Chromium carbon nitride (CrCN) hard films own high hardness, lower friction coefficient, higher wear and corrosion resistance. Investigations on the surface roughness of <span style="mso-fareast-font-family:DFKai-SB" lang="EN-GB">CrCN hard films become an important issue because the surface roughness of <span style="mso-fareast-font-family:DFKai-SB" lang="EN-GB">CrCN hard films is widely believed to be related to its characteristics of wear and corrosion resistances. This paper presents a low-cost optical inspection system for rapid surface roughness measurements of <span style="mso-fareast-font-family:DFKai-SB" lang="EN-GB">CrCN hard films. <span style="mso-fareast-font-family: DFKai-SB" lang="EN-GB">Surface roughness of hard films<span style="mso-fareast-font-family:DFKai-SB" lang="EN-GB"> can be determined rapidly from the average value of the reflected direct current voltage by the developed optical system<span style="mso-fareast-font-family:DFKai-SB" lang="EN-GB">. The measurement results are in good agreement with the results of white-light interferometry measurements. <span style="mso-fareast-font-family: DFKai-SB" lang="EN-GB">The deviation between both approaches is less than 10.07%. The savings in measurement time of the surface roughness of hard films<span style="mso-fareast-font-family:DFKai-SB" lang="EN-GB"> is up to 83%. </span></span></span></span></span></span></span></span></span>
