A Synergistic Enhancement on Corrosion and Tribocorrosion Resistance Properties of the Multilayered Mo2N/AlCrN Coatings in Artificial Seawater

This study demonstrates that multilayered Mo₂N/AlCrN coatings deposited on 304 stainless steel via arc ion plating exhibit superior hardness, toughness, and corrosion resistance in artificial seawater compared to individual MoₓN and AlCrN coatings, owing to synergistic mechanisms involving fcc solid solution strengthening, self-lubricating molybdenum oxides, and protective passive films.
