PASSIVATION AND LOCAL ACTIVATION OF BULK IRON-BASED NANOCOMPOSITES CONTAINING CARBIDE AND NITRIDE INCLUSIONS
The corrosion-electrochemical properties of bulk nanocrystalline iron-based composites with carbide and nitride inclusions, which were produced by mechanochemical synthesis followed by pressing, are studied. The passivation of composites containing titan is found to be determined by the formation of FeO· x TiO 2 mixed oxides. Nitride containing composites are characterized by highest resistance against pitting corrosion.
