Self-propagating high temperature synthesis preparation method of titanium carbide dispersion strengthening copper-based composite material
2009
The invention discloses a self-propagating high temperature synthesis preparation method of a titanium carbide dispersion strengthening copper-based composite material, which utilizes Cu powder, Ti powder and C powder with the granularity less than 100 meshes and the purity larger than 99% as raw materials, wherein the mass ratio of Cu powder to Ti powder to C powder is 50:50-70:30, and the mol ratio of Ti powder to C powder is 1:1. The preparation method comprises the following steps: mixing a certain amount of Cu powder, Ti powder and C powder, then carrying out high energy ball mill for 3-10 hours at room temperature, carrying out cold press molding on the mixed powder, finally adopting electric arc to ignite pressed shapes in a vacuum room to prepare the TiC dispersion strengthening copper-based composite material through the self-propagating high temperature synthesis of the pressed shapes, wherein, the average granularity of TiC granules is 2-8 mu m. The simple self-propagating high temperature synthesis method is adopted to lead the Cu powder, Ti powder and C powder to react in situ and synthesize, so as to prepare the TiC dispersion strengthening copper-based composite material, and has the advantages of simple process, low production cost, high product output, high quality and the like.
