In this work, soil corrosivity of the central desert of Iran was investigated by analyzing the physical-chemical characteristics of soils, weight loss testing, and electrochemical measurements.
The proposed multilayer coating system comprises three layers fabricated using physical vapor deposition, with a Zn–Mg layer sandwiched between two zinc layers. Galvanizing steel with zinc increases its corrosion resistance, making it a sustainable and economical choice to use in construction and infrastructure. Researchers believe it can improve the longevity of steel.
