Abstract
An ultrafine-grained surface layer of a pure Mg sheet was fabricated by sliding friction treatment. The grain size of the surface for the treated sample was reduced to 300 nm from 50 μm for the as-received counterpart. The ultrafine-grained pure Mg shows significantly enhanced corrosion resistance compared to its coarse-grained counterpart, representing a lower mass loss, a higher polarization resistance and a smaller hydrogen volume, mainly attributed to the relatively compacted film formed on the sample surface.
