Abstract
The disclosure relates to a method of obtaining a good current contact on the support bar of a cathode used in electrolysis. In this method a highly electroconductive layer is formed on the contact piece on the end of the support bar of the cathode, especially at the point that comes into contact with the electrolysis cell busbar. The electroconductive layer forms a metallic bond with the contact piece of the support bar. The disclosure also relates to the cathode support bar, wherein a highly electroconductive layer is formed to the contact piece on the end of said bar, in particular the area that touches the electrolysis cell busbar.
