Abstract

In this paper is described the influence of alloying elements on corrosion behavior of sintered iron parts. The compacts were sintered at 1,150 °C and the  sintering time was 60 minutes. After microstructural studies, the electrochemical tests were carried out. The corrosion behavior of samples was evaluated using potentiodinamic polarization technique in 3.5% NaCl solution. Different parameters like icorr, cathodic (βc) and anodic (βa) slopes derived after the extrapolation of the Tafel plots were obtained. The results reveal that the alloying elements can improve significantly corrosion resistance of iron based sintered P/M alloys.
