Abstract
Disclosed are a composite material having an anti-wear property and a process for producing the same. The composite material includes a matrix of a low melting point Sn alloy having a melting point of from 80.degree. to 280.degree. C., and metallic dispersing particles dispersed in the matrix in an amount of from 10 to 50% by volume. When the composite material is utilized to make a rough mold for preparing a prototype, it sharply improves the anti-wear property of the rough mold, and it can be re-used for a plurality of times without adversely affecting the sharply improved anti-wear property. The composite material provides the advantageous effect best when the metallic dispersing particles are Fe--C alloy dispersing particles and/or Fe--W--C alloy dispersing particles which were subjected to a surface treatment including an Sn or Ni electroplating followed by a ZnCl.sub.2.NH.sub.4 Cl flux depositing.
