Wear-resistant protective coating

Considered modern technologies for the formation of composite detonation crystalline and amorphous-crystalline coatings, their friction and wear under the conditions of the presence and absence of lubricant, compatibility with structural and antifriction materials, as well as the influence of the stress state on their formation. The monograph consists of six chapters. Chapter 1 discusses the general issues of friction and wear research of composite detonation coatings in the absence of lubricant. It is shown how the sliding speed affects the wear of the friction surfaces. The evaluation of the features of wear in conditions of heavily loaded contact and the formation of coatings in conditions of elevated temperatures is given. Chapter 2 shows how the presence of lubricant affects the wear of composite detonation coatings. The role of tribochemical processes in the formation of wear-resistant surface structures and the wear resistance of coatings in the presence of lubricant in contact, the influence of elemental-organic additives on the processes of friction and wear are revealed. Chapter 3 deals with the compatibility of coatings with antifriction and structural materials. On the basis of the obtained results, friction pairs from structural and antifriction materials were selected, as well as the operational stability of detonation coatings in these friction pairs was studied. Chapter 4 describes the principles of forming amorphous and amorphous-crystalline coatings. The selection and justification of the components of the wear-resistant amorphous-crystalline coating, their influence of the nature of alloying elements on the properties of zirconium-based coatings are considered. The influence of technological parameters of detonation sputtering on the formation of detonation amorphous-crystalline coatings Chapter 5 presents the results of research on friction and wear of amorphous-crystalline coatings in the absence of lubricant. The wear resistance of amorphous-crystalline coatings in friction with tested coatings was studied. The wear resistance of amorphous-crystalline coatings with aircraft steels and the patterns of wear of amorphous-crystalline coatings with anti-friction materials were studied. Chapter 6 examines the features of the formation of the stress state of amorphous-crystalline detonation coatings. An assessment of the level of technological residual stresses in friction pairs and their effect on wear resistance was carried out. The influence of residual stresses on the wear resistance of the obtained coatings is shown. For researchers, engineers, as well as teachers, graduate students and students of higher educational institutions dealing with the problems of formation and research of detonation coatings.
