Abstract
Specimens with a bi-metallic interface are formed by laser cladding. The S960 high-strength steel is chosen as a substrate material to which a layer of either aluminum bronze or hard chrome is applied. The change of fracture-mechanical properties of bi-metallic interface, bonding area, and the heat-affected zone are tested by Vickers microhardness. The Young's modulus of a particular layer is calculated and several conclusions are drawn that describe the behaviors in the vicinity of the bi-material interface.
