6061 aluminium alloy is an important material with wide ranges of industrial applications and marine technology. This study examines the use of milk for improvement of corrosion resistance of 6061 aluminium alloy in sodium chloride. Weight loss method and potentiodynamic polarization measurement were employed to study the corrosion behavior of 6061 aluminium alloy in sodium chloride. The weight loss method showed that the presence of milk significantly decreases the corrosion rates of 6061 aluminium alloy 6061 in the test solutions. Pitting corrosion take places in all the specimens during immersion test and the pitting can be seen through surface analysis by using optical microscope 200x magnifications.
