Abstract
Pulse current electrodeposition of Sm-Co alloys from aqueous solutions has been studied at various current densities (PCD), solution temperatures, frequency (ν), Ton and duty cycles (γ). A deposit content of 20 at %Sm was obtained at 25oC, higher than at 60oC in contrast to DC from bath of 1M Sm sulfamate, 0.05M Co sulfate, 0.15M glycine at pH6. This composition is sufficient to obtain the high performance permanent magnet intermetallics, Sm2Co17 (10.5 at %) and SmCo5 (16.7 at %), by appropriate heat treatment. Increased PCD, Ton, g and decreased solution temperature or frequency increased Sm deposit content and decreased current efficiency (CE). Magnetic saturation(Ms) decreased linearly with increased Sm deposit content as DC and sputtered films. Increased Sm content resulted in significant decrease in Hc⊥ but Hc|| varied little.
