Abstract
First and second aluminum members are joined by the steps of (a) dissolving and removing completely the aluminum oxide layer from the surface of each of the first and second members to be joined and replacing each of the aluminum oxide layers with a layer consisting essentially of zinc; (b) plating at least one of the zinc layers with a non-alloy cadmium; (c) assembling and retaining together the first and second aluminum members so that the surfaces to be joined are held in contact with one another and placing the aluminum members in a vacuum; and (d) heating the members while in the vacuum thereby forming a bond between the first and second aluminum members.
