Abstract

In this paper an advanced solid state cladding process, based on Friction Stir Welding, is presented. The Friction Surface Cladding (FSC) technology enables the deposition of a solid-state coating using filler material on a substrate with good metallurgical bonding. A relatively soft AA1050 filler material is deposited on a relatively hard AA2024-T351 substrate and the results are discussed. Depending on the process conditions, the filler material is deposited on top of the substrate or mixed through the surface region of the substrate. The cladded surface regions are analyzed using SEM-EDX, optical microscopy and micro hardness measurements to identify the resulting microstructure and establish the degree of mixing.
