Alloy composition, hardness and corrosion performance (ASTM B117 & potentiodynamic polarization) relative to the base aluminum alloys 6061 & 2070. The thermodynamically stable nanocrystalline aluminum alloys provide improved corrosion resistance.
The newest generation of aluminum, high strength steel and magnesium alloys show significant potential for light weight applications in aerospace, transportation and consumer electronic applications. However, these alloys suffer from significant corrosion problems. To address this issue, a series of nanostructured binary aluminum alloys (AlCr, AlMn, AlZr) have been prepared and tested for corrosion performance. The composition of these single-phase alloys, created via electrodeposition from ionic liquids, can be tuned to adjust microstructure and modify properties such as hardness and pitting potential in order to target application specific requirements. Here we present data on alloy composition, hardness and corrosion performance (ASTM B117 & potentiodynamic polarization) relative to the base aluminum alloys 6061 & 2070. Results show that the thermodynamically stable nanocrystalline aluminum alloys provide improved corrosion resistance as compared to the base alloys.

Mild steel specimens (API 5L X65) were pretreated to form a pyrrhotite layer on the surface using high temperature sulfidation in oil, then exposed to a range of aqueous CO2 and H2S corrosion environments, leading to initiation of localized corrosion.
The objective of the present study was to evaluate the effect of alloying elements (Cr, Mo and Cu) on the corrosion behavior of low carbon steel in CO2 environments. Six samples were prepared with varying Cr content from 0 to 2 wt.% and with added 0.5 wt.% of Mo and Cu.
