Effect of Al thin film and Ni foil interlayer on diffusion bonded Mg-Al dissimilar joints

Diffusion bonded Mg-Al joints with and without an interlayer were produced. An Ni foil interlayer eliminated the formation of Mg-Al intermetallic compounds, while addition of an Al thin film to the interlayer improved the properties of the Mg-Ni intermetallic compounds. The shear strength of the joints was improved by the addition of the Ni foil and Al thin film interlayer. (C) 2012 Elsevier B. V. All rights reserved.
