Abstract

The paper presents the results of studying external force effect on the formation of tribological structures at the stage of "BrAZhMts10-3-1, 5 - AMG-10 - 30KhGSA" system burn-in. Based on analytical model of friction and wear processes, burn-in characteristics, namely time and wear, were defined. Experimental data, processed by methods of mathematical statistics, allowed establishing maximum permissible loads for the burn-in stage, coefficient of friction force variation 10% corresponded to the burn-in finish and beginning of a stationary mode of system operation. It is shown that stepwise increase of load, frictional heat emission regulation and constant sliding speed activate the burn-in process, expand the area of maximum permissible loads, thus reducing time and wear, as well as the probability of jamming, grip and denial of burn-in. It was found that as a result of burn-in, carbon-saturated tribological structures are formed,due to mechanical destruction of oils and surface-to-surface transfer of positively charged elements.
