The effect of cutting ShKh15 hardened steel on the element and phase composition of the surface layer of the coating deposited on the cBN-based tool is studied. The microstructure and oxidation kinetics of the surface layer of the AlN–Ti(Cr)B 2 magnetron coating are investigated during both formation and turning. The coating is formed by HF magnetron sputtering of an AlN–Ti(Cr)B 2 target. The formation of a two-layer tribofilm with a nanosize outer layer is examined. The phase composition of the tribofilm is determined using layer-by-layer Auger analysis. Its outer nanosize layer is a glass-like phase in the form of limited solid solutions based on Al 2 O 3 oxides and playing a role of solid lubricant. As the cutting speed is increased, the wear rate for the coated tool decreases compared with the uncoated tool.
