Investigation on the Corrosion Behavior of Reinforced Recycled Aluminium Cans by Leadwood Particles

Abstract:

Corrosion refers to the deterioration of both metal and non-metal objects caused by their electrochemical reactions with the environment around them. The objective of this study work is to investigate the corrosion characteristics of Aluminium that has been strengthened with leadwood particles. Aluminium and organic leadwood particles were combined through the process of smelting and stir-casting, using various weight ratios. Linear politization method was used to determine the corrosion rate. Taffel plots were used to determine the polarization potential and the corrosion current. The results indicated that Leadwood can be successfully used to reinforce and enhance the corrosion resistance of Aluminium. 2% leadwood reinforced sample was corroding at a rate of 1.3366mm/yr, an improvement of 37.5% to the parent Aluminium sample (2.1416mm/yr), while the 3% pulverized leadwood reinforce sample’s corrosion rate was 1.9053mm/yr (10.9% corrosion improvement).
