An Investigation of Abrasive Wear Behaviour of Al 2014-SiC Composites
In this study, the effects of SiC reinforcement volume fractions on hardness, porosity and abrasive wear behaviour were examined in Al 2014-SiC (<92.3 μm) reinforced metal matrix composites (MMCs) of 3%, 6% and 12% reinforcement–volume (R-V) ratios produced by melt-stirring. Abrasive wear tests w...

| description | In this study, the effects of SiC reinforcement volume fractions on hardness, porosity and abrasive wear behaviour were examined in Al 2014-SiC (<92.3 μm) reinforced metal matrix composites (MMCs) of 3%, 6% and 12% reinforcement–volume (R-V) ratios produced by melt-stirring. Abrasive wear tests were carried out by 320 mesh Al2O3 abrasive paper and a pin-on-disc wear test apparatus, under 10N, 20N and 30N load, and at 0.2 ms−1 sliding speed. The same specimens were tested by 150, 240 and 320 mesh abrasive paper at 0.2 ms−1 sliding speed, under 10N, 20N and 30N load. After the tests, the microstructures of the worn surfaces were examined with scanning electron microscope (SEM) studies and EDS analyses. Besides, the amount of hardness and porosity of the specimens were identified. It was recorded that the amounts of hardness and porosity increases as the SiC reinforcement in the composite increases. The highest amount of abrasive wear was recorded in the specimens with 3% reinforcements. It was identified that the amount of abrasive wear decreases while the SiC reinforcement in the composite structure increases by volume, and that the amount of porosity and reinforcement volume (R-V) ratio are important parameters in abrasive wear. |
