Abstract Scope |
Friction surfacing (FS) is a solid state layer deposition technique based on friction and plastic deformation that shows strong potential for coatings, additive manufacturing and repair applications. The solid state process induces less heat, leading to less pronounced re-heating cycles, compared to fusion-based approaches and various material combinations are feasible. To further optimize and develop the FS approach towards application, it is necessary to understand the deposition processes, for instance, the transferring mechanism from consumable material to deposited layer, as well as the resulting microstructure and mechanical properties of the layer or structure deposited. Compared to the respective base material, the FS-deposits typically present a significantly refined microstructure achieved via dynamic recrystallization. Slight grain size gradients along deposit thickness and width can be related to the material flow from consumable stud forming the layer. However, compared to other fusion-based layer deposition approaches, FS-deposited structures present a very homogeneous microstructure. |
