Abstract
To improve the corrosion resistance of a metallic layer which is being burned off by electrodes, and decrease the contact pressure of the electrodes by eliminating metallic residues upon an electrical discharge between an electrode and a metallic surface, the metallic surface layer is a two-metal system having a top layer of aluminum and an intermediate layer of nickel, the metals, upon electrical discharge in air, reacting in an exothermal reaction if the energy level of the electrical discharge between the electrode and the metallic surface is sufficient to initiate the reaction.
