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.

烧结温度对SiC增强锌镁基复合材料物理力学行为的影响

摘要

目前的研究工作是研究烧结温度对Zn ₂ Mg ₆的物理和机械性能的影响。SiC复合材料，可以用作可生物降解的植入物。复合材料的烧结已在430°C，450°C，470°C和490°C的温度下进行。已经观察到样品的机械和物理性能随烧结温度而变化。已观察到样品的晶粒尺寸在450°C时最佳，晶粒尺寸为0.2587 µm，并为样品提供了最大的强度。发现所获得的复合材料的致密化在450℃下最大，值为90.30％。在此温度下，观察到磨损率，硬度，弹性杨氏模量和弯曲强度最大。在不同温度下对样品进行扫描电子显微镜和X射线衍射光谱分析，以发现复合材料的微观结构变化和表面形态。
