dc.description.abstractThe effect of phosphating on the corrosion resistance of a commercial Nd-Fe-B sintered magnet has been investigated. Sintered magnet specimens were phosphated in solutions of 10 g/L NaH(2)PO(4) (pH 3.8), either with or without molybdate [10(-3) M MoO(4)(2)], for improving their corrosion resistance. The effect of phosphating time was also evaluated, with specimens phosphated during 4 hours and 18 hours. To evaluate the corrosion performance of phosphated and unphosphated specimens, a corrosion test based on monitoring hydrogen evolution on the magnets surface was used. This technique revealed that molybdate addition into the phosphating solution improves the corrosion resistance of the phosphated magnets for shorter periods of immersion but has no beneficial effect for longer phosphating times.
