THE FRICTION AND WEAR CHARACTERISTICS OF SI3N4 CERAMIC AGAINST SI3N4 CERAMIC ZRO2 CERAMIC AND CHILLED CAST IRON AND AL2O3 CERAMIC UNDER DRY FRICTION
Preview AbstractThe friction and wear of silicon nitride (Si3N4) against silicon nitride (Si3N4) and zirconia (Y–TZP) and chilled cast iron and Alumina sliding under dry friction at room temperature conditions were investigated with pin-on-disk tribometer at sliding speed of 0.56ms-1 and normal load of 50N, 80N, respectively. Based on the variety regulation of the wear maps, the wear mechanisms of the two couples were analyzed. Get the result of friction coefficient and maps of wear Rate of the Pin and the Disk. The results of comparing this couple is Si3N4/ chilled cast iron < Si3N4/ ZrO2< Si3N4/ Si3N4< Si3N4/ Al2O3.
