The corrosion behaviour of Inconel 600 and 601 alloys has been evaluated by DC polarisation method in orthophosphoric acid solution of concentrations 0.5N to 15N. The passivation range from + 200mV to + 800mV has been observed for 601 alloy. In the case of Inconel 600 a less passivation range in comparison with Inconel 601 is observed. In addition, the passivation current has been found to be higher than that of 601 alloy. Tafel polarisation study indicates that Inconel 601 alloy is more corrosion resistant than Inconel 600.
