摘要: The corrosion performance of Mo-22Si and Mo-25Si alloys in 0.5 M sodium chloride (NaCl) hydroxide (NaOH) solutions, at room temperature, was evaluated using electrochemical techniques. In NaCl, additionally, the effect solution pH (3, 7 10) concentration (0.1, 1.0 M) studied techniques such as potentiodynamic polarization curves, linear resistance noise current. alloy contained either α-Mo or Mo5Si3 phases a Mo3Si matrix. Polarization results showed that only containing 22Si developed passive film NaOH solution, whereas 25Si passivated 10 solution. with one highest rate, most resistant. NaCl exhibited localized type corrosion, but not solutions. Alkaline solutions increased rate 75Mo-25Si respect to acidic neutral diluted (0.1 concentrated (1.0 produced lower rates than Some occurred due selective
