Abstract
The study of the electrochemical behavior of a soft magnetic amorphous Fe–P–Mo alloy in a 0.1M Na2SO4 solution, which simulates a damp SO2-contaminated atmosphere, shows that the corrosion resistance of the nanocrystalline Fe80.2P17.1Mo2.7 alloy is comparable to that of a FINEMET alloy. No molybdenum is required for manufacturing the Fe80.2P17.1Mo2.7 alloy, because it can be prepared using natural alloy ferrophosphorus containing molybdenum.
