Korosi Retak Tegang (Stress Corrosion Cracking) Pada Aluminium Seri 1100 Dalam Larutan Sodium Klorida

Abstract

This research focuses on understanding the factors that cause corrosion in 1100 series aluminum, specifically in the context of stress corrosion cracking. Corrosion is an electrochemical reaction between a metal and its environment, such as water, seawater or other solutions. Materials with sustained internal or residual stresses have higher corrosion rates. Aluminum is an important material in various industries due to its strong properties, good electrical conductivity, and corrosion resistance. However, aluminum is also susceptible to corrosion in certain situations. Therefore, an understanding of corrosion and how to control it is essential to maximize the benefits of this metal. Analyzed how changes in bending angle affect resistance to Stress Crack Corrosion. Examined the impact of temperature variation on resistance to Stress Cracking Corrosion. Furthermore, the research involved a tafel anode polarization test to calculate the corrosion rate. The results showed that the bending angle and the concentration of sodium chloride solution had a significant effect on the corrosion rate. The greater the bending angle, the higher the corrosion rate. This study provides an in-depth understanding of the phenomenon of stress corrosion cracking of 1100 series aluminum under various conditions. The results can be used to improve corrosion control in industrial applications using this aluminum.
