Corrosion Behavior Studies of Al7075 Reinforced with Multiwalled Carbon Nanotubes Metal Matrix Composites in Acidic Medium

摘要

The attempts to use the Carbon nanotubes as the reinforcements in the Metal matrix composites is engulfing worldwide since it possess excellent material properties which improves the composites strength. The present work was carried out to test the corrosion behavior of the Al7075 Composites prepared with the carbon nanotubes as the potential reinforcements. The composites were added to the base material in 2wt%, 4wt%, and 6wt % via liquid metallurgy procedure the corrosional studies were conducted as per the Mass loss technique using HCl solution of varying Normalities of 1N, 2N and 3N the weight loss during the period of 10 weeks the observations were made in the gap of each week upto 10 weeks and obtained the mass loss data in each week later the corrosion rate was calculated. The corroded specimens were then analysed using SEM. The results revealed that as the wt% of the MWCNTs was increased the Corrosion rate was found to be decreased.
