<p>This study investigates the enhancement of A356 aluminium alloy through the incorporation of synthesised nano-titanium carbide (n-TiC) particles (2.5–10 wt%) to improve mechanical, tribological, and corrosion performance for automotive applications.

摘要

This study investigates the enhancement of A356 aluminium alloy through the incorporation of synthesised nano-titanium carbide (n-TiC) particles (2.5–10 wt%) to improve mechanical, tribological, and corrosion performance for automotive applications. The composites were produced through stir casting and systematically evaluated. The 10 wt% TiC composite demonstrated the highest performance, with an ultimate tensile strength of 211.9 MPa, a yield strength of 186.4 MPa, and a hardness of 112.56 BHN. These improvements are attributed to grain refinement, uniform TiC dispersion, and the formation of Al–Ti intermetallic phases, which enhanced interfacial bonding. However, composites with higher TiC content exhibited increased wear rates (600 and 500 µm) due to particle agglomeration and porosity. The results highlight the potential of TiC-reinforced A356 composites for advanced structural applications requiring a balance of strength, wear resistance, and corrosion durability.
