| Abstract: | Chromium
carbon nitride (CrCN) hard films own high hardness,
lower friction coefficient, higher wear and corrosion resistance.
Investigations on the surface roughness of CrCN hard
films become an important issue because the surface roughness of 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 CrCN hard films. Surface roughness of hard films can
be determined rapidly from the average value of the reflected direct current
voltage by the developed optical system. The measurement results are in good
agreement with the results of white-light
interferometry measurements. The deviation between both approaches is less than 10.07%. The
savings in measurement time of the surface roughness of
hard films is
up to 83%.
