Improved corrosion resistance of IrMn by Cr and Ru additions
Abstract
The magnetic and corrosion properties of Ir16Mn84 with Ru and Cr additions were investigated. The corrosion current and potential were Ic = 8 μA/cm2 and E0 = -580 mV respectively, for Ir16Mn84 with 12 vol% Cr. Results showed that when Ru was used as additive, Ic and E0 were 10 μA/cm2 and -100 mV, respectively, for 9 vol%.
