Abstract

The literature on adaptive materials and wear-resistant coatings on cutting tools for blade cutting is analyzed. The results of theoretical and experimental studies of the operational properties of sintered tool materials based on high-speed steel with additional alloying with additives, which provide a significant increase in the wear resistance of the cutting tool, are presented and this phenomenon is explained from the point of view of adaptation (self-organization) during friction by forming secondary structures. In this case, the secondary structures play a dual role: lubricating and protective in the form of amorphous compounds.
