Abstract

The urgent problems of modern materials science include the problem of increasing the durability and operational reliability of moving joints of machine parts. At the same time, the use of complex oxide compounds, in particular, magnesium oxide as a material for friction units is of considerable interest. In addition, it is important to develop compositions that can act as solid lubricating oils under friction conditions.
The objective of the work is to determine the patterns of friction and wear of a composite coating based on oxide compounds of magnesium with structurally free magnesium carbide and to study their structural-phase composition and influence on the formation and self-organization of surface structures.
Magnesium orthosilicate was used as a material for spraying, to which alloyed impurities from chromium, nickel, titanium, aluminum powders, etc. were added. The initial composition for spraying was obtained by the method of mechanical-chemical synthesis. The physical and mechanical properties and patterns of friction and wear of the coatings were studied using the end-face scheme in the continuous sliding mode under constant load. The complex methodology included metallography, durometric analysis, scanning electron microscopy and phase X-ray structural analysis.
Highly effective coatings based on magnesium orthosilicate, characterized by improved antifriction properties, were developed. The optimal mode of detonation-gas spraying of the proposed coatings was determined. The nature and patterns that determine the tendency of the coatings to passivation were studied.
The results of the studies of the friction and wear patterns of the proposed detonation coating and their structural-phase composition and features of self-organization of surface structures expand the understanding of modern tribological materials science.
