Investigation of wear mechanisms for the rake face of a cutting tool with a multilayer composite nanostructured Cr–CrN-(Ti,Cr,Al,Si)N coating in high-speed steel turning

The article considers the wear pattern for the rake face of a cutting tool with the Cr–CrN-(Ti,Cr,Al,Si)N multilayer composite nanostructured coating in turning 1045 steel at vc = 300 m/min. Attention was paid to the diffusion and oxidation processes and effect of high temperature because these wear factors prevailed at high cutting speeds. Studies were conducted using a high-resolution transmission electron microscope and energy-dispersive...
