Ultra-high frequency induction and conventional sintering of Al-SiO2 composites: A comparative study

In this study, it was aimed to determine and compare the sinterability of aluminum-SiO composites by conventional and fast sintering methods and to examine their tribological properties after the sintering process. For this purpose, 1, 3, 5, 9, and 15 wt.-% SiO reinforced aluminum matrix composites were sintered by a conventional and induction sintering method at 600 °C after uniaxial cold pressing under 200 MPa pressure. The sintering was performed for 30 minutes for the traditional method and 5 minutes for induction sintering. After the sintering, the microstructures of the samples were examined, and their sintered densities and hardness were determined. In addition, the tribological properties of the samples were investigated by the pin-on-disc method, and the worn surfaces were examined after the tests.
