PROCESS FOR PRODUCTION OF STEEL PLATE/ALUMINUM PLATE JOINT STRUCTURE, AND STEEL PLATE/ALUMINUM PLATE JOINT STRUCTURE PRODUCED BY THE PROCESS

摘要

PPROBLEM TO BE SOLVED: To provide a process for the production of a steel plate/aluminum plate joined structure which can effectively suppress the contact corrosion in the contact face between the steel and aluminum material, and a steel plate/aluminum plate joint structure with excellent contact corrosion resistance produced thereby. PSOLUTION: A process for producing a joint structure of a steel plate and an aluminum plate, in which the steel plate and the aluminum plate are joined to each other so as to be electrically connected to each other. The process comprises a step of forming at least one resin coating film in a thickness of 0.1 to 5.0 μm on a contact surface on the steel plate side, wherein the resin is selected from the group consisting of a polyolefin resin, a polyurethane resin and an epoxy resin.
