The influence of saccharin and sodium lauryl sulfate on the electrodeposition process of Co-Ni alloys

Co-Ni alloys, obtained as a result of cathodic codeposition, are characteri sed by high strength, hardness and good corrosion resistance. Depending on the bath composition and the electrolysis parameters it is possible to obta in alloys of various composition, and consequently having different physica l properties. The present paper contains the results of the study of the in fluence of additional substances (saccharin, sodium lauryl sulfate) on the composition and morphology of Co-Ni alloys and cathodic current efficiency. The experiments were carried out under galvanostatic conditions in Watts-t ype electrolyte.
