| 500 ## - GENERAL NOTE | |
| General note | The Automotive and Aerospace industry is revolutionizing driven by advancement in<br/>material. Aluminum and its alloys are of prime importance for weight reduction, but the<br/>growing demand of industry needs more advanced materials to enhance the mechanical<br/>and tribological properties. Aluminum is reinforced with different particles or fibers.<br/>Graphene or graphene derivatives are one of the hardest and highest strength materials.<br/>Graphene reinforced aluminum metal matrix composites (GRAMMCs) are of great interest<br/>due to their intrinsic properties such as high specific strength, high specific stiffness, low<br/>density, good oxidation resistance and enhanced tribological performance and are used in<br/>aerospace and automobile industry. Graphene oxide with its exceptional strength material<br/>could be a promising reinforcement in aluminum metal matrix composites to boost their<br/>mechanical properties. This study was conducted to develop graphene oxide and zirconia<br/>reinforced hybrid Al6061 metal matrix nanocomposites by using liquid phase sintering in<br/>an inert atmosphere. Graphene oxide concentration was varied at 0.2 wt.%, 0.4 wt.%, 0.6<br/>wt.% and 1.0 wt.% while zirconia concentration was maintained constant at 2 wt.% ZrO2.<br/>All the composite samples were sintered at 500°C and 550°C with dwell times of 60 min,<br/>120 min and 180 min. Optical microscopy and scanning electron microscopy was<br/>employed to study the microstructure while compression test was performed to evaluate<br/>the compressive strength of composites. The relative sintered density was measured by<br/>Archimedean principle and is found maximum for the sample<br/>0.2wt.%GO/2wt.%ZrO2/Al6061.There is 23% improvement in microhardness and 16%<br/>improvement in compressive strength by adding 0.6wt.% graphene oxide in the sample<br/>0.6wt.%GO/2wt.%ZrO2/Al6061 sintered at 550°C for 180min and is found maximum<br/>among all composites. |
