Fluoroplast-containing antifriction composites for lowspeed operation

Abstract

The main differences between antifriction and friction materials during the operation of technical units, machines and individual elements are considered. Experimental studies of the tribological properties of antifriction polymeric fluoroplastic composite coatings at low speeds have been carried out. The results of studies of antifriction polymer composites under conditions of low-speed operation are presented. It has been determined that in the investigated range of speeds, the temperature during friction depends mainly on the load, which affects it 43.7 % more intensively than the speed. Coefficients of friction of the coating were revealed in the investigated range of modes (? 0.2 at ? = 15 MPa). As a result of the research carried out, the resource of antifreeze composites is provided, corresponding to the 8th class of wear resistance.
