Corrosion behavior of aluminium alloy AA6063 in acidic media

Abstract

The main purpose of the study of corrosion behavior of aluminum alloys 6063 in acidic media is to investigate the way of aluminum being protected with suitable corrosion inhibitor. This is because aluminum alloys 6063 was widely use in multi purpose industry.In this case, sodium benzoate is used as the protector or medium to inhibit and lower the process of corrosion. The acetic acid (0.5M) and sulphuric acid (0.1 M) have been chosen for this purpose. This research investigates the corrosion of aluminum alloy 6063 as variation of temperature. The samples were immersed in the acid media with the temperature of 283K, 293K, 303K, 313K, 323K, and 333K.The methods that used in this research are weighing the weigh lost of the sample and corrosion rate. To get the condition of corrosion and composite of the sample surface, the Scanning Electron Microscopy (SEM)) and Energy Dispersive Spectroscopy (EDS) analysis were used.
