The invention relates to a method for achieving a good contact surface on an aluminium electrode support bar used in electrolysis. In the method the support bar is fabricated as a continuous bar and a highly electroconductive layer is formed on its end. The highly electroconductive layer forms a metallic bond with the support bar and can be achieved for example with thermal spray coating. The invention also relates to an electrode support bar, the end of which is coated with a highly electroconductive material.

L'invention concerne un procédé permettant de former une bonne surface de contact sur une barre support d'électrode en aluminium utilisée en électrolyse. Dans le procédé, la barre support est fabriquée sous forme de barre continue et une couche fortement électroconductrice est formée sur une extrémité de celle-ci. La couche fortement électroconductrice forme une liaison métallique avec la barre support, et peut être formée par exemple par pulvérisation thermique. L'invention concerne aussi une barre support d'électrode dont une extrémité est revêtue d'une matière fortement électroconductrice.
