The invention belongs to the field of
metal materials and particularly relates to a TiC / Ti5Si3 enhanced
copper-based composite and a preparing method thereof. The preparing method includes the steps of
raw material preparing, preparing of carbon elementary substance mixed
powder of Ti, Si,
graphite and the like,
powder briquetting and
sintering, preparing of the TiC / Ti5Si3 enhanced
copper-based composite and other steps. By means of the TiC / Ti5Si3 enhanced
copper-based composite and the preparing method thereof, carbon elementary substances such as
graphite powder or
carbon black or carbon nano tubes or
graphene are adopted as the
carbon source, and the carbon elementary substances in melt and
titanium are subjected to a
spontaneous reaction to synthesize TiC so as to prepare the TiC / Ti5Si3 enhanced copper-based composite. The preparing technology is simple, the cost is low, and the efficiency is high. TiC particles are distributed in Ti5Si3,
interface bonding between an enhancement body and a base body is good, and particle and
fiber compounding enhancement is achieved. Compactness of the prepared composite is high, electric conduction performance and heat conduction performance are good, strength,
hardness and
wear resistance are high, meanwhile, good
plasticity and
toughness are achieved, and the TiC / Ti5Si3 enhanced copper-based composite is suitable for industrial production and application.
