A METHOD FOR OBTAINING A GOOD CONTACT SURFACE ON AN ELECTRODE SUPPORT BAR AND A SUPPORT BAR

摘要

The invention relates to a method for forming a good contact surface on an electrode support bar used in electrolysis, where at least part of the bar is made of copper. In the method a highly electroconductive layer is formed on at least one end of the copper section. The highly electroconductive layer forms a metallic bond with the copper of the support bar, which can be achieved preferably with either thermal spray coating or soldering technique. The invention also relates to an electrode support bar either partially or wholly made of copper, of which at least one end is coated with a highly electroconductive material.
