Duplex coatings consisting of nitrided HSS steel substrates and (Zr,Al)CN layers were produced. Plasma nitriding of the steel was carried out for 3 h in an atmosphere of N 2 (30%) and H 2 (70%) gases, at 480°C. The (Zr,Al)CN coatings were deposited by cathodic arc technique on the nitrided steel surfaces. For the nitrided layer, a thickness and surface microhardness of about 60 μm and 1580HV0.02, respectively, were measured. The (Zr,Al)CN coatings, with a highly over stoichiometric composition ((C+N)/(Zr+Al) ~ 2) and single solid solution nanostructure, had hardness of - 36 GPa and a thickness of - 4.8 μm. The duplex coatings produced were found to exhibit superior friction and wear performance when compared to plasma nitrided substrates.
