Abstract
In the manufacture of sheet metal elements or strip having a catalytic surface structure, a mixture of skeleton material powder, and of Raney alloy powder is rolled onto the starting sheet metal element or strip substrate, sintered in a reducing atmosphere, whereafter the soluble component of the Raney alloy is dissolved out. To ensure an adequate adherence of the catalytic surface structure, the operation in which the above-mentioned mixture is rolled onto the substrate is accompanied by a simultaneous cold-working of the substrate with a deformation of 20 to 60% within each cold-forming step. The coated sheet metal element or strip substrates or any spherical bodies made therefrom serve as electrodes in electrolytic processes.
