Wear Behavior and Its Correlation with Mechanical Properties of TiB2 Reinforced Aluminium-Based Composites

الملخص EN

Aluminium-based TiB2 reinforced composite is a promising material to be used as brake drum material, and it may emerge as substitute for conventional gray cast iron.

Aluminium-based composites containing 2% by wt copper reinforced with 2.5 and 5 wt% TiB2 composites were made in induction furnace by in situ synthesis process using simultaneous addition of halide fluxes (K2TiF6 and KBF4).

These cast composites were evaluated for microstructures, hardness, flow curve properties, and tensile properties.

It was observed that overall wear behavior gave reasonably good correlation with mechanical properties of composites as compared to gray cast iron.
