THE INFLUENCE OF SACCHARIN AND SODIUM LAURYL SULFATE ON THE ELECTRODEPOSITION PROCESS OF Co-Ni ALLOYS

摘要

Co-Ni alloys, obtained as a result of cathodic codeposition, are characterised by high strength, hardness and good corrosion resistance. Depending on the bath composition and the electrolysis parameters it is possible to obtain alloys of various composition, and consequently having different physical properties. The present paper contains the results of the study of the influence 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-type electrolyte.
