Enhancing Tribological Characteristics of AA6061-SiC Composites via Response Surface Methodology

The work described in this paper focuses on a thorough examination of the tribological characteristics of silicon carbide (SiC)-reinforced AA6061 aluminum matrix composites. Tribological characteristics, such as wear resistance and frictional behavior, play a crucial role in deciding whether these composites are suitable for use in different engineering applications. By adjusting important process parameters, this study uses the Response Surface Methodology (RSM) as a statistical tool to improve the tribological properties of the AA6061-SiC composites. With different weight % of SiC particles AA6061-SiC composites are made using stir casting technique in this experiment. A pin-on-disk tribometer is used to perform tribological tests under various operating circumstances. RSM is used to examine the generated data and create predictive models that show how the process parameters relate to tribological performance. The results of this work provide important light on the interactions between SiC reinforcement and processing parameters that affect the tribological characteristics of AA6061-SiC composites. In addition, the complicated trade-offs inherent in the design of composite materials is addressed by the RSM-derived models, which make it easier to identify the ideal conditions to improve wear resistance and reduce friction. © 2023, The Institution of Engineers (India).
