PRODUCTION OF Cu-TiB2 BULKS FOR PARTS WITH HIGH ELECTRICAL CONDUCTIVITY AND WEAR RESISTANCE

Abstract

A copper matrix-based composite powder containing 40 wt% TiB2 particle was in-situ synthesized by combination of preliminary mechanical milling of the Cu-Ti-B elemental mixture and subsequent selfpropagating high temperature synthesis (SHS) reaction. In order to fabricate Cu-based composites with low TiB2 content as electrical conducted materials, pure Cu powder was added to the 40 wt% TiB2 powder to form composite powders Cu-2.5, 5 and 10 wt% TiB2...
