Abstract

The friction and wear performance of Ti-12Mo alloy fabricated by powder injection molding (PIM) were investigated. It was compared with that of as-PMed Ti and TC4 alloy and as-cast TC4 alloy, which is the most widely used in the dental materials field. The results show that the Ti-12Mo alloy exhibits higher wear resistance than the as-PMed Ti and TC4 alloy, and it is close to the as-cast TC4 alloy under the same sliding friction conditions. The Ti-12Mo alloy shows a typical Widmanstatten structure, consisting of β-Ti and α-Ti phases. The microhardness (HV) of Ti-12Mo alloy is about 3100 MPa, and the friction coefficient is stabilized at about 0.43, which are lower than those of the other three alloys. The wear mechanisms of Ti-12Mo alloy (PIM) is dominated by abrasive wear.
