Friction Surfacing Cladding (FSC) is a recently developed solid state process to deposit thin metallic clad layers on a substrate. The process employs a rotating tool with a central opening to supply clad material and support the distribution and bonding of the clad material to the substrate. The tool is held at a given distance above the substrate and translates relative to the substrate while the clad material is pressed out and deposited. This work studies the effect of the tool rotation speed and the clad layer thickness on the deposition quality of AA1050 clad layers on top of AA2024-T351 substrates at constant process temperatures. Well bonded, defect free clad layers with uniform thickness and width are produced. A 2D axisymmetric thermal-flow model predicts the influence of the process parameters and confirmed the experimental observations.
