Abstract

Spark plasma sintering (SPS) was used to synthesize Nano-structured Fe-18Cr-2Si alloy with Fe-18Cr-2Si ball milled powders. SPS was carried out in vacuum at three different holding time (5, 10 and 15min) at a fixed sintering temperature (1100 °C) and applied pressure (50MPa). Potentiodynamic Polarization (PDP), Linear Polarization (LPR) and Electrochemical Impedance Spectroscopy (EIS) were used to study the effect of sintering time on the electrochemical properties of nanostructured alloy in deaerated 0.2M NaCl and 0.5M H₂SO₄ solutions respectively. Corrosion resistance measured in terms of corrosion potential (Ecorr), pitting potential (Epit) and passive current density (ip) was found to be increased with an increase in holding time. Density of the samples was measured by Archimedes' method and results showed the highest density for the specimen sintered for 15 min at 1100 °C.
