Corrosion behavior of Mg–8Li–3Zn–Al alloy in neutral 3.5% NaCl solution

The corrosion behavior of Mg–8Li–3Zn–Al alloy was investigated in neutral 3.5% NaCl aqueous solution by morphology observation and electrochemical tests. The weight loss method was to measure the corrosion rate. The electrochemical results indicated that the corrosion resistance of Mg–8Li–3Zn–Al alloy in 3.5% NaCl solution is poorer than that in distilled water. The Cl- anion leads to the initiation and development of the corrosion pits. And the corrosion products are mainly Mg(OH)2.
