Abstract
An electroplating bath for depositing cobalt-phosphorus alloys comprises a solution containing 20-30 gm./litre of complexed cobaltous chloride (calculated as CoCl2.6H2O), 50-100 gm./litre of hypophosphite ions (calculated as NaH2PO2.H2O) and a conductivity salt, the solution having a pH of 7-9. The complexing agent described is the tartrate ion present as 30-200 gm./litre of sodium tartrate but citrate may also be used. The temperature of the bath is 50-80 DEG C. and during plating the current density is 25-125 amps./sq.foot. The substrate may be rotated during deposition. The conductivity salt may be NH4Cl, KCl or NaCl.
