Abstract
Since a powder-produced material comprises cerium fluoride, it can exhibit good wear-resistance. The cerium fluoride content may be set in the range of from 0.1 to 22% by weight, in particular, in the range of from 0.1 to 10.0% by weight, based on the total weight of the powder-produced material. The powder-produced material may comprise a ferrous matrix including hard particles, and the ferrous matrix includes cerium fluoride.
