摘要

The article discusses the influence of the thickness of nanolayers (from 10 to 302 nm) in the Ti-TiN-(Ti,Al,Cr)N multilayer composite nanostructured coating on the adhesion component of the coefficient of friction (COF) within a range of temperatures from 500 to 1000 degrees C, the coating microhardness, the wear rate of the cutting tools, and fracture patterns on the coatings during the cutting process. The coating structure was investigated using the scanning electron microscopy (SEM) and transmission electron microscopy (TEM) methods. An increase in temperature for coatings with various nanolayer thicknesses causes a growth and then a decline of f(adh) (an adhesion component of the COF). The studies revealed three temperature ranges (500-600, 700-800, and 900-1000 degrees C), characterized by different effects of the nanolayer thickness lambda on f(adh). There is a relationship between the nanolayer thickness and the wear rate of the cutting tools and the fracture patterns on the coatings during the turning of stainless steel at various cutting speeds (v(c) = 60, 70, 90, and 100 m/min). The lowest wear rate of the cutting tools at low cutting speeds (60 m/min) is demonstrated by the coatings with the nanolayer thickness of 16 nm (coating K7), and at high cutting speeds (90 m/min and 100 m/min) - by the coatings with the nanolayer thickness of 10 nm.
