ABSTRACT:
A method for bonding a metal substrate to a similar or dissimilar substrate by first applying a primer coating to the surface of the metal substrate and then bonding the primed metal substrate to the other substrate. At least part of the primer coating is composed of a uniform, ultra-thin film that is formed by immersing, prior to bonding, the metal substrate in a solution that has undergone substantially no polymer growth. The solution contains at least one hydrolyzable metal alkoxide of a polymer network-forming cation, water, a solvent and a base. The metal substrate is allowed to react with the solution for a time sufficient to form in situ an ultra-thin film on the metal substrate.
