Tribological properties of multilayer coatings

Abstract

Deals with the methods of increasing the wear resistance of the cutting tool due to the formation of an additional anti-friction layer of perfluoropolyether on the surface. Experimental studies have been carried out using modern techniques and equipment to reveal the mechanism of influence of the coating and the scientific validity of the hypothesis put forward about their lubricating action and adaptability to the conditions of friction when cutting metals. The results of natural experimental studies of wear resistance and tribotechnical characteristics of multilayer coatings for high-speed steel cutting tools during turning and milling are presented. The results of metalgraphic studies by SIMS and AES methods to establish the appearance of secondary structures with unique properties. The use of these coatings in the conditions of modern machine-building production, which uses expensive and high-performance machine tools with low cutting properties of the cutting tool, can significantly improve the efficiency of blade machining metal cutting.
