摘要：

The wear resistance of coatings, chip formation conditions, microstructure and chip shrinkage, the angle of the conventional shear plane were studied. The data on the characteristics of the surface structure and the adhesion of such coatings, etc., were studied and analyzed. It is shown that the main reason for high wear resistance of these coatings during high-speed processing is the formation of thin protective oxide films on the surface of a tool made from aluminum oxide with a complex amorphous-crystalline structure. Such protective films significantly improve the friction and wear characteristics of coated tools: the adhesion of the tool surface to the workpiece decreases and the thermal intensity of the cutting zone decreases due to the intense heat removal into the chips.
