Abstract
A method of forming diffusion bonds between aluminum and aluminum alloy saces by coating the surfaces with molten AgNO.sub.3 and then decomposing the AgNO.sub.3 to form a thin uniform layer of silver on the surfaces before forming the diffusion bond. The AgNO.sub.3 coating and decomposition in treatment permanently breaks up the Al.sub.2 O.sub.3 coatings on the aluminum or aluminum alloy surfaces, making diffusion bonding possible.
