Abstract

The invention discloses a method for preparing a TiC-reinforced copper-based electric contact composite material. The preparing method includes the steps of raw material preparation, carbon source manufacturing, powder briquetting and sintering, TiC self-forming reaction synthesis and the like. The method for preparing the TiC-reinforced copper-based electric contact composite material has the characteristics that the preparation technology is simple and stable, cost is low, efficiency is high and the method is suitable for industrial production and application. The carbon source used in the preparing method refers to Cu-graphite coated TiC mixed powder obtained by ball milling, the grain size of synthesized TiC is 0.5-2.0m, and TiC grains are evenly distributed on a copper substrate. Theprepared TiC-reinforced copper-based electric contact composite material is high in compactness, good combination of the strength, hardness, electrical conductivity and thermal conductivity of the composite material can be realized by adjusting the content of the TiC, and the high-strength and high-conductivity characters are achieved.
