摘要
A series of PVD ceramic hard coatings (TiN, 21 N, TiAlN, TiZrN and TiCN) were deposited on steel substrates using the cathodic arc/unbalanced magnetron deposition technique. These coatings were characterised using Raman microscopy to elucidate the behaviour of the optic and acoustic phonon modes of the (cubic) crystalline lattices. Defect-induced first- (and second-) order spectra have been observed in the 200-300 and 500-800 cm(-1) regions and these have been assigned and correlated with coating composition. Changes in the position, intensity and shape of the principal TO band (640-560 cm(-1)) have been interpreted. Raman microscopy has been shown to be a very useful non-destructive complementary technique to XRD for the characterisation of PVD hard coatings. (C) 1999 Elsevier Science S.A. All rights reserved.
