Influence of titanium dioxide on mechanical and tribological properties of aluminium 7050 composite for aerospace application

Purpose The purpose of this study is to optimize the properties of Aluminium 7050 alloy through the incorporation of titanium dioxide-reinforced composites, focusing on their metallurgical, mechanical and tribological characteristics for aerospace applications. A comprehensive review of existing literature and consultations with industry experts have identified a research gap centered on determining the optimal percentage of titanium dioxide reinforcement within AA7050 composites to enhance their properties and understanding the mechanisms governing wear behavior. This research introduces an innovative approach by synthesizing AA7050 composites with varying percentages of titanium dioxide reinforcement, thereby enabling tailored property enhancements while investigating wear mechanisms. Design/methodology/approach The methodology used in this research adopts a systematic approach to enhance the properties of pure aluminum, with a specific emphasis on the AA7050 alloy. This study uses the concept of composite materials, as indicated by previous research, to effectively tailor these properties. AA7050 composites are synthesized through liquid metallurgy processing, incorporating titanium dioxide at varying weight percentages. The research encompasses a series of metallurgical, mechanical and tribological examinations to evaluate properties, microstructures and wear behaviors. Findings The research findings indicate that the incorporation of titanium dioxide into aluminum 7050 alloy markedly enhances its mechanical and tribological properties. Specifically, there is a notable improvement in wear resistance, tensile strength and fracture toughness, with optimal conditions identified at particular reinforcement levels and sliding distances. Originality/value The research provides significant practical implications for improving the properties of aluminum alloys, particularly within the automotive and aerospace sectors, through the application of tailored composite materials and alloying elements.
