reportActive / Technical Report | Accession Number: ADD014685 | Need Help?

Abstract:

A method of forming diffusion bonds between aluminum and aluminum alloy surfaces by coating the surfaces with molten AgNO3 and then decomposing the AgNO3 to form a thin uniform layer of silver on the surfaces before form the diffusion bond. The AgNO3 coating and decomposition treatment permanently breaks up the Al2O3 coatings on the aluminum or aluminum alloy surfaces, making diffusion bonding possible. Patent applications. js
