Composite material having anti-wear property and process for producing the same

摘要

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 DEG to 280 DEG 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 advantages 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 ZnCl2.NH4Cl flux depositing.
