Abstract
A flowable composite particle that includes a plurality of bound hard particles and a binder alloy. The bound hard particles are unfractured bound hard particles and fractured bound hard particles. Each of the bound hard particles is bonded to the binder alloy. The bound hard particles have a particle size of −325 Mesh. The flowable composite particle have a particle size distribution is: (a) between more than about zero weight percent and about 5 weight percent flowable composite particles of a +80 Mesh particle size, (b) between about 60 weight percent and about 95 weight percent flowable composite particles of a −80+325 Mesh particle size, and (c) between more than about zero weight percent and about 35 weight percent flowable composite particles of a −325 Mesh particle size.
