The Synthesis, Wearing Properties of Titanium Carbide Particle Beams Reinforces the Cast Iron Matrix Overall Composite Materials by In Situ

Abstract:

This paper describes a wire composite method which consists of the use of a cast-penetrated-heat treatment process to elaborate cast iron and titanium silk. After 12 h at 1138 °C heat preservation and oven cooling, the cast iron matrix in situ generated a titanium carbide particle beam that reinforced the iron matrix composites as a whole. By XRD, the SEM (EDS) on the overall composite material of the macro and micro structure and composition distribution were studied. The results showed that the titanium was fully reflected and it generated fascicles in the titanium carbide hard phase of particles and uniform distribution. Analysis of single wire on the composition and morphology observation found that the titanium carbide particle beam presents three characteristics: uniform dispersion, long strips, and an aggregation phase. The ML-100 abrasive wearing-testing machine, with two bodies of titanium carbide, reinforced iron matrix composites overall the wearing experiment that was carried out: the result shows that its wearing resistance is about 4.2 times greater than the cast iron standard sample.
