Parameter Study for Friction Surface Cladding of AA1050 on AA2024-T351

Friction Surfacing Cladding (FSC) is a relatively new solid state process to deposit thin metallic clad layers on substrates. It employs a hollow rotating tool that supplies the clad material. Frictional and viscous heating take place that soften the clad material and enhance the bonding of the clad material to the substrate. Thin layers of commercially pure aluminium can be deposited well on an AA2024 aerospace aluminium alloy. Homogeneous and defect free layers with a ne grained microstructure can be manufactured. The relatively low heat input and normal forces exerted on the substrate during the FSC process assure a minimal in uence of the process on the mechanical properties of the substrate.
