Abstract

Aluminium alloy 2024 is widely used in heavy industry. The aim of this study was to report on the corrosion behaviour of this alloy when exposed to selected environments of different acids and salts containing chloride, nitrate and sulphate ions and measure the corrosion rate by using the weight loss method at room temperature. The results obtained indicate that, under the conditions employed in the present work, the corrosion rate of this alloy depends on the specific ions present in the solution. Gravimetric analysis confirmed that with varying the exposure periods the weight loss of the alloy decreases and the corrosion rate can be described as an initial steep rise followed by subsequent fall.
