Joining Dissimilar Materials Using Three-Dimensional Electrodeposited Film

Abstract

In this study, the effect of the shape of Ni-Cu alloy electrodeposited films, which was changed by using different concentrations of Ni amidosulfate in a plating bath, on the joint strength of stainless steel/CFRTP and aluminum alloy/CFRTP lap joint specimens was investigated. A lap joint specimen with the stainless steel and CFRTP joined using the Ni-Cu alloy electrodeposited film made of 450 g/L Ni amidosulfate showed an average joint strength of 18.4 MPa, which is higher than any of the other conditions. The average joint strength of the aluminum alloy/CFRTP ranged from 7 to 10 MPa.
