The Investigation of Electrochemical Corrosion Behaviour of Fe Matrix Composites at Room and Elevated Temperatures
In this study, pure Fe and Fe matrix composites (5 wt. % nano-Al2O3, 5 wt. % micron-B4C and 2.5 wt. % nano-Al2O3-2.5 wt. % micron-B4C) were manufactured via powder metallurgy. The density and phase analysis of the produced samples were performed. The electrochemical corrosion behaviour of the sample...

| Summary: | In this study,
pure Fe and Fe matrix composites (5 wt. % nano-Al2O3, 5
wt. % micron-B4C and 2.5 wt. % nano-Al2O3-2.5
wt. % micron-B4C) were manufactured via powder metallurgy. The
density and phase analysis of the produced samples were performed. The
electrochemical corrosion behaviour of the samples in a 3.5 wt. % NaCl solution
was studied using potentiodynamic polarization at 25, 50 and 75 ºC. The
corrosion rate of the samples significantly increased with increasing test
temperature. Also, the effect of reinforcement particulates leads to
deteriorate corrosion resistance of pure Fe due to the presence of galvanic
reactions. |
