Corrosion and corrosion inhibition in crystalline and amorphous metallic alloys

Corrosion is an ubiquitous phenomenon of major industrial importance. The state of the surface is known to have a critical effect on the corrosion rate. It is well known that amorphous surfaces, both metallic and oxide, have higher corrosion resistance than crystalline surfaces. We study CuZr-based alloys which can be produced with both crystalline and amorphous structure with the same chemical composition, which allow us to relate the different corrosion resistance to the surface topology. We study the effect of corrosion inhibitors in both CuZn and CuZr alloys in order to find new strategies to improve the corrosion resistance of Cu-based materials.
