Özet

This paper concerns the wear and friction properties of multilayer hard coatings on WC(Ti, Ta, Nb, W)C-Co hard metal substrates for cutting tool applications. The nuiltilayer hard coatings with TiCN+TiC+TiCN+Al2O3+TiN configuration were deposited at the temperatures of 800-1000degreesC by using a high temperature chemical vapour deposition (HTCVD) process. The nuiltilayer coatings were characterized by X-ray diffraction, and scanning electron microscopy (SEM). It was found that all multilayer coatings have a dense and homogeneous surface morphology. The multilayer hard coatings (BK-247) with 7.5 mum showed the best wear resistance under 50 N. It as also deterinined that the Ti-410 specimens with 10.5 mum thick had the best wear resistance at 200 N.
