Abstract

The corrosion-electrochemical behavior of composite layers obtained by high-speed laser sintering of Fe-C ultrafine powders (C in the amount of 0.5 ± 0.1 wt %) is studied using a recording of anodic poteniodynamic curves in borate buffer solutions in neutral and weak alkaline mediums. It is demonstrated that these layers formed on the surface of the steel substrate show the capacity for passivation. Variations in the surface composition and properties of the materials that occur in the course of laser sintering are confirmed using X-ray structural and X-ray electron analyses.
