Popis: | 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. |
