Abstract: Under optimized operating parameters,a hard and wear resistant (Ti,AI)N film is prepared on a normalized T8 carbon tool steel substrate by using pulsed high energy density plasma technique.Microstructure and composition of the film are analysed by x-ray diffraction,x-ray photoelectron spectroscopy,Auger electron spectroscopy and scaflning electron microscopy.Hardness profile and tribological properties of the film are tested with nanojndenter and ring-on-ring wear tester,respectively.The tested results show that the microstructure of the film is dense and uniform and is mainly composed of (Ti,AI)N and AIN hard phases.A wide transition interrace exists between the film and the normalized T8 carbon tool steel substrate.Thickness of the film is about 1000nm andmean hardness value of the film is about 26 GPa.Under dry sliding wear test COnditions,relative wear resistance of the(Ti,AI)N film is approximately 9 times higher than that of the hardened T8 carbon tool steel reference sample.Meanwhile.the (Ti,Al)N film has low and stable friction coefficient compared with the hardened T8 carbon tool steel reference sample.
