Effect of Sintering Temperature on the Physico-Mechanical Behavior of SiC Reinforced Zinc-Magnesium Based Composite

Abstract

Abstract: The present research work deals with study the effect of sintering temperature on the physical and mechanical behavior of Zn2Mg6SiC composite, which can be used as a biodegradable implant. Sintering of the composite has been done at a temperature of 430 °C, 450 °C, 470 °C and 490 °C. The mechanical and physical properties of the samples have been observed to vary with sintering temperature. The grain size of the samples has observed to be optimized at 450 °C with grain size 0.2587 µm and provides maximum strength to the samples. The densification of the composites achieved was found to be maximum at 450 °C having a value 90.30%. Wear rate, hardness, Young’s Modulus of elasticity and flexural strength were observed to be maximum at this temperature. Scanning electron microscopy and X-ray diffraction spectroscopy of the samples at various temperatures were done to find microstructural changes and surface morphology of the composite.
