ABSTRACT:
An Fe-P alloy film is electrodeposited on a workpiece in a bath comprising 20-80 g/l ferrous ion, 0.01-15 g/l hypophosphorous acid and/or a hypophosphite, and 0.05-5 g/l aluminum ion or a bath comprising 20-80 g/l ferrous ion and 0.01-20 g/l phosphorous acid and/or a phosphite, and optionally aluminum ion at 10.degree.-80.degree. C. and 0.5-30 A/dm.sup.2. There is obtained a crack-free alloy film having a P content of 0.1 to 9.9 wt %.
