Abstract
The corrosion properties of the nanostructured Al84Ni7Gd6Co3 alloy produced by hot pressing of the metallic glassy powder, have been investigated. The results reveal that the nanostructure Al84Ni7Gd6Co3 alloy shows different corrosion behavior compared to the pure aluminum, because of the presence of high volume fraction of Al-based intermetallic compounds. The corrosion resistance of Al84Ni7Gd6Co3 alloy is significantly influenced by the amount of aluminum and porosity in the inter-particle area. The main corrosion mechanisms observed in the Al84Ni7Gd6Co3 alloy are found to be the pitting corrosion (corrosion of aluminum in the consolidated particles) and crevice corrosion (corrosion of aluminum in the inter-particle area).
