The invention generally relates to new materials based on C49 titanium disilicide (TiSi.sub.2) as a new, layered anode material, within which lithium ions can react with the Si-only layers. Stabilization by a coating a thin layer of oxide on the surface of TiSi.sub.2 significantly improves the charge and discharge performance.

A sliding member includes at least one surface having a particle aggregate of base material particles and hard particles. The hard particles are iron-based alloy particles containing molybdenum silicide in an amount of 35% to 90% by area. The sliding member has a wear resistance equivalent to that of a sliding member that uses cobalt-based hard particles.
