摘要

本工作的目的是使用浸渍腐蚀技术评估纳米氧化石墨烯增强铝（Al/GO）金属基复合材料在不同浸渍时间段的腐蚀行为。采用超声波重力搅拌铸造工艺制备了Al/GO复合材料。用扫描电子显微镜评价了Al/GO的腐蚀性。实验结果表明，随着浸泡时间的增加，腐蚀速率降低，重量损失增加。与浸渍的Al/GO复合材料相比，未熔融的Al/GO复合材料表现出更高的显微硬度值。

Corrosion and Hardness Behaviour of Al/GO Nanocomposites Processed by the Ultrasonic Gravitational Stir Casting Method

The objective of this work is to evaluate the corrosion behaviour of nanographene oxide reinforced aluminium (Al/GO) metal matrix composites with different immersion time periods using the immersion corrosion technique. The Al/GO composites were fabricated by the ultrasonic gravitational stir casting process. The corrosions of Al/GO were evaluated using a scanning electron microscope. The experimental results revealed that the corrosion rate decreased and weight losses increased with increasing immersion time periods. The nonimmersed Al/GO composites exhibited higher microhardness values compared to the immersed Al/GO composites.
