Effect of Molybdenum-Rich Carbides on Wear Behavior of Powder Metallurgy Steel

Effect of molybdenum-rich carbides on wear behavior of the powder metallurgy (P/M) steel was studied. Wear-resisting property of the couple part was also studied. The friction pair materials have low wear ratio. M2C carbides and M6C carbides exit in the P/M steels. Crisp M2C carbides decrease wear-resisting property of the materials obviously. While fine grainy M6C carbides are beneficial to good wear-resisting property of the materials. [doi:10.2320/matertrans.M2012063]
