SPECIAL TECHNOLOGIES

Spiridonov B. A., Sharuda V. A. � Bidirectional pulse current cobalt coating electrodeposition from sulphate electrolytes

We studied cobalt electroreduction from sulphurous electrolytes with monoethanolamine by the potentiometeric method. Effect of the reverse pulse current on the cobalt coatings electrodeposition and some of their properties was investigated. X-ray diffraction method was used to establish interrelation between the phase composition of the cobalt coatings and electrolyte pH. We obtained that β-Co fallout from acid electrolyte (�� 1,0 and 1,7), and generally α-Co does from the less acid ones (�� 3,0). It was established that by changing parameters of the reverse pulse current one can obtain shining and fine-grained coatings with lesser internal stress.
