Evaluation of wear properties of Al 7075 alloy reinforced with herbal extracted SiC

Mechanical Engineering

This study investigates the wear behaviour of Aluminium 7075 alloy reinforced with silicon carbide (SiC) particles derived from natural herbal sources. Rather than fabricating new composites, the research focuses on evaluating the tribological performance of existing materials under varying operational parameters such as applied load, rotational speed, and test duration. Key output responses including coefficient of friction, wear rate, surface roughness, and frictional force were measured. To determine the optimal combination of these parameters for enhanced wear resistance and surface quality, Grey Relational Analysis (GRA) was employed as a multi-response optimization technique. The findings demonstrate that herbal extracted SiC reinforcement contributes to improved wear properties of the aluminium alloy, and GRA proves to be an effective approach for performance optimization in material studies.
