Antifriction self‐lubricating glass composite coatings of the Sic‐Ni‐Cu‐Al‐Si‐C type additionally contain an aluminoborosilicate glass phase and structurally free MgC2, which forms α ‐graphite during thermolysis, the synergistic effect of which causes modification of the friction surface due to the formation antifriction layer. The influence of the structural components of the coating on their contribution to the antifriction properties is considered. It was clarified that an increase in the adhesive strength of the coatings was achieved by preliminary application of a sublayer of vitreous sodium silicate. The developed coatings showed high performance properties, while the means of minimizing and stabilizing wear characteristics was the presence of a thin‐film antifriction layer based on α ‐graphite, which shields unacceptable processes of molecular‐adhesive interaction.
