Kind Code:
A1
Abstract:
Provided is a TiCx-(Ti-Mo) sliding material having a binder phase that comprises a Ti-Mo alloy, and a hard phase that includes TiCx, wherein the TiCx-(Ti-Mo) sliding material is characterized by satisfying all of the following conditions: (1) the total area of the binder phase and the hard phase is 90% or more of the visual field area; (2) the total area of the binder phase is 15-20% of the visual field area; (3) the total area within the binder phase that corresponds to a case of a diameter of 10-50 µm, calculated under the assumption that the area is the area of a circle, is 60-80% of the total area of the binder phase; (4) the total area within the binder phase that corresponds to a case of a diameter of less than 10 µm, calculated under the assumption that the area is the area of a circle, is 20-40% of the total area of the binder phase; and (5) the Mo concentration in the binder phase is 25-35 wt%.
