CONTACT SURFACES FOR ELECTRICAL CONTACTS AND METHOD FOR PRODUCING THE SAME

摘要

A method of making contact surfaces for electrical contacts in which a metal is deposited on a copper-based substrate by a galvanic process. The metal is deposited on the substrate along with a placeholder material that can easily be dissolved out of the metal. The placeholder material is then dissolved out of the metal layer, and the remaining porous metal foam is impregnated with a lubricant.
