摘要：
Deterioration behavior, for pure Mg, Mg–5Al, Mg–10Al, and Mg–15Al alloys, was explored in neutral solutions comprising different chloride ion concentrations. Different electrochemical methods were used and enhanced by a scanning electron microscope (SEM) investigation. It was observed that the presence of 5% Al leads to a substantial improvement in the corrosion resistance and a reduction of hydrogen evolution. Also, a developed corrosion and hydrogen evolution proportion is gotten with growing chloride ion concentration. This investigation is significant for an industrial application owing to the low cost and light weight of the magnesium alloys. © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
