Study on Tribology Performance and Wear Controlling of 9Cr2Mo Steel

Xiao Ming Jia, Jin Rong Chai

Abstract

9Cr2Mo steel is widely used as measuring and cutting tool steel. The friction and wear behavior of 9Cr2Mo steel was investigated under dry friction and solid lubricant by wear tester. The experiment results show that the friction coefficient of 9Cr2Mo steel is 0.34~0.58 under dry friction and 0.035~0.06 under solid lubricant. With the increase of load , the friction coefficient decreases and the wearing capacity increases under two kinds of conditions. The wearing capacity of 9Cr2Mo steel under solid lubricant is great lower than it under dry friction. The friction process is smooth under solid lubricant. It indicated that the solid lubricant took effect in antifriction and antiwear of 9Cr2Mo steel.
