Experimental analysis and investigation on enhanced tribological performance of self-healing Al6061–60Pb40Sn solder alloy reinforcement
In this study, we investigate a self-healing 60Pb40Sn reinforced Al6061 alloy’s tribological behavior through experimentation, focusing on the influence of different reinforcement concentrations on tribological performance. Cylindrical pins with varying filler concentrations were tested using a pin-on-roller Tribometer to evaluate friction behavior, wear resistance, and fractured surface morphology. The results revealed intriguing findings, including a 5% higher coefficient of friction (COF) for the maximum solder concentration sample at lower loads and speeds. Under higher loads (100 N), the COF increased by approximately 16%. However, the three-hole pin samples consistently exhibited higher weight loss than the two-hole pins. Remarkably, at a 100 N load and extended sliding distances, the three-hole pins showed slightly lower friction values, with a reduced COF of 12%, 16%, and 12% at 53 rpm, 106 rpm, and 160 rpm, respectively. Morphological characterization using Scanning Electron Microscope (SEM), Energy Dispersive Spectrum (EDS), and Elemental Maps revealed the wear mechanism and oxidation on the pins’ surfaces, contributing to enhanced wear resistance in this self-healing composite, thus presenting a novel insight into self-healing alloy tribology.
