摘要

This research intends to synthesize and enrich the aluminium alloy (Al7075) alloy with 0–3 weight percentages of titanium carbide and 1–5 wt% of silicon carbide (SiC) nanoceramics through a solid-state process. Various functional properties, including metallographic, mechanical, and wear behaviour of the aluminium alloy and its hybrid nanocomposites, are studied according to the American Society for Testing and Materials (ASTM) standards. Metallographic results reveal a homogenous distribution of the particles (TiC and SiC). X-ray diffraction analysis shows various peaks related to the contribution of TiC and SiC. The Al7075/2 wt% TiC/4 wt% SiC is found to have an optimum hardness (124 HV), compression strength (538 MPa), better impact toughness (21.1 J/mm2), reduced wear loss (0.0125 g), and increased coefficient of friction (0.43). The optimum hybrid nanocomposite of Al7075/2 wt% TiC/4 wt% SiC is proposed for automotive roof applications.
