Rapid Development of Surface Treatment Processes for Bonding Dissimilar Materials
A recent concept in automotive lightweighting is that of the ‘joining of dissimilar materials.’ The purpose is to allow tailoring the materials in a structure so as to ensure that each part of the structure has the optimum mechanical properties and minimum weight. An example would be the bonding of...
