Abstract
The article is devoted to the study of structural changes occurring in the contact layers of carbon steels during friction with a hard alloy. The relevance of this work is due to the need to understand the processes occurring in the friction zone in order to develop more effective lubrication methods, reduce wear and increase the durability of mechanisms. The purpose was to study the mechanism of build-up formation as a result of stagnant processes during cutting. To achieve this goal, experimental methods were used, including electron microscopy, X-ray diffraction analysis and other methods. The scientific novelty of the work is to develop the features of the mechanism of structural changes in the contact layers of 20, 45, U8 steels during friction while cutting, affecting adhesion to a hard alloy. The results of studies of structural changes in steels during contact with a hard alloy are presented. It is shown that as a result of high deformation rates and contact loads, high-speed heating and the formation of nonequilibrium structures affecting adhesion to a hard alloy are realized. The practical significance of the work lies in the possibility of using the results obtained to develop new technologies capable of increasing the wear resistance and durability of mechanisms operating under friction conditions with hard alloys. In addition, the results of the study may be useful for developing new lubricants and reducing wear of cutting tools. The direction of development of this work may include further study of the effect of various wear-resistant nanostructured coatings on reducing the coefficient of friction and wear of cutting tools during the cutting process. Such tools are characterized by increased hardness of the surface layer and high heat resistance, they are resistant to oxidative and corrosive processes, demonstrate low tendency for adhesion to the processed material and exhibit stable strength properties.
