Al coating by arc thermal metal spray gives significant protection to mild steel.

Blocking effect to pores/defects are exerted by corrosion products.

XRD and Raman spectroscopy revealed the formation of α-Al(OH)3 on coating surface.

A schematic model is proposed to explain the corrosion phenomena of Al coating.
