摘要：

Electrodeposition of cobalt-chromium alloys of different compositions (up to 14 at% Cr) has been carried out onto copper cathode by the pulse potential and the pulse current methods from cobalt chloride-N-(n-butyl)pyridinium chloride (BPC) molten salt containing chromium(II) chloride at 110 degreesC. The magnetic properties of the deposited cobalt-chromium alloys have been investigated. The magnetic polarization of the deposited cobalt-chromium alloys at high fields decreases with the increase of chromium content in the deposit except Co-1.22 at% Cr alloy, with maximum magnetic polarization than the bulk cobalt. The cathodic current efficiency for the deposition of alloy is about 99 %.
