In this study, an attempt was made to enhance the mechanical and microstructural properties of aluminium (Al) based FGM with the influence of silicon carbide (SiC) elements. The five layered functionally graded metal-ceramic composite was fabricated using powder metallurgy technique. The bottom layer of the specimen was compacted with aluminium (100 wt.%) and succeeding layers were made with the combination of Al and SiC (97.5–2.5 wt.%, 95-5 wt.%, 92.5–7.5 wt.%, 90-10 wt.%). FESEM analysis ensured the smooth transitions of microstructure between adjacent layers which confirmed the good interfacial solid state bonding. The major orientation (111) of Al and SiC was improved with the volume percentage of SiC. Moreover, the addition of SiC has been improved the crystallite size of Al/SiC. Vickers analysis resulted the maximum hardness of 148.5 Hv on FGM when SiC was added by 10%. The corrosion resistant property can be improved by adding non-conductivity element of SiC in the Al based FGM.

在这项研究中，试图通过碳化硅（SiC）元素的作用来增强铝（F）基FGM的机械和微观结构性能。采用粉末冶金技术制备了五层功能梯度金属陶瓷复合材料。样品的底层用铝（100 wt。％）压实，随后的层由铝和碳化硅（97.5-2.5 wt。％，95-5 wt。％，92.5-7.5 wt。％， 90-10重量％）。FESEM分析确保了相邻层之间微观结构的平稳过渡，从而确认了良好的界面固态键合。Al和SiC的主取向（111）随着SiC的体积百分比而改善。而且，SiC的添加已经改善了Al / SiC的微晶尺寸。维氏分析得出最大硬度为148。当添加10％的SiC时，FGM上的Hv为5 Hv。通过在Al基FGM中添加SiC的非导电性元素，可以提高耐腐蚀性。
