Results of investigation of composite powders with dry lubricants of FeCr-TiC-Mo-C and Cr2O3-TiO2-CaF2 systems, as well as thermal coatings of a tribotechnical purpose, are presented. Conditions of thermal spraying are defined, providing dense coatings with a high adhesion and cohesion strength at a sufficiently uniform distribution of a dry lubricant across the section.
Keywords: thermal coatings, structure, phase transformations, dry lubricants, friction coefficient, wear resistance, friction without lubrication
