Abstract
Corrosion-electrochemical behavior of composite layers formed by high-speed laser sintering of nanoscale Fe-Ni powders (3.2 and 10 wt % Ni) is studied with the use of anodic potentiodynamic curves recorded in a borate buffer solution in a neutral environment. Composite layers produced are shown to retain nanostructure properties of the original iron and nickel powders. The layers formed exhibit better passivation properties than do iron and nickel separately. Changes in the composition and properties of the surface layers formed by laser sintering before and after corrosion studies are confirmed by X-ray diffraction and X-ray photoelectron analyses.
