COMPUTER DESIGN OF THCT PROCESS FOR OBTAINING SIC SOLID-FILM LUBRICANT ON STEEL Y8
The results examination of the frictional properties of solid-film lubricant, obtained by thermohydro-chemical treatment of high carbon steel У8 (0,8 wt. % С), are presented. Optimization of the suspension composition and temperature - time parameters of the process was performed for the friction coefficient of the films. The diagrams “property vs. process parameters” were plotted using the obtained mathematical expressions. Treatment with optimal regime permits decreasing the friction coefficient of the tool steel surface in 5,3 as compared with untreated.
