Electrochemical corrosion of Tb-Fe films was studied by immersion in a NaCl solution. The corrosion resistance was improved by adding Al, Cr, Hf, Mo, and/or Ti to Tb-Fe. The improvement mechanism, which was studied by transmittance change measuring, microscopic observation, and electron probe microanalysis, is the concentration of the additive metals and formation of passive states by the metals.
