An Investigation of Localized Corrosion of Al 2024 under Fully Immersed Condition of Chloride (HCL) Media
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2017, Vol 7, Issue 4
Abstract
Al 2024 is an important engineering material, which is used in aerospace, marines, & automotive field. It is employed in many process industries cause of low density, High strength, corrosion resistance and low cost. The present study aims to investigate the corrosion behavior of Al 2024, under varying proportion of normality’s and temperatures variation, respectively in chloride media. Corrosion testing is evaluated through fully immersion weight loss method in HCL solution with different Normality’s that is 0.25N,0.50N,0.75, and 1N, at variation in temperature 300,600, 800 for 6, 12, 18, to 36 days. Corrosion characterization is done to investigate the effect of microstructure on its performance, and to study the effect of temperature on corrosion rate. The change in micro hardness is observed to be quite significant after being exposed to the chloride Acidic solution having pH 1 at different temperature for regular interval of 6 days over a period of 36 days. More-over, morphology and chemical compositions of corrosion behavior of Al 2024 under varying normality and temperature condition was analyzed through SEM and EDS.
