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

Abstract

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.
