摘要

Pulse current electrodeposition of Sm-Co alloys from aqueous solutions has been studied at various peak current densities (PCD), solution temperatures, frequency (v), T_(on) and duty cycles (γ). A deposit content of 20 at %Sm was obtained at 25°C, higher than at 60°C 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, Sm_2Co_(17) (10.5 at %) and SmCo_5 (16.7 at %), by appropriate heat treatment. Increased PCD, T_(on), γ and decreased solution temperature or frequency increased Sm deposit content and decreased current efficiency (CE). Magnetic saturation (M_s) decreased linearly with increased Sm deposit content as DC and sputtered films. Increased Sm content resulted in significant decrease in He_⊥but Hc‖ varied little.
