Combined experimental-numerical analysis of the temperature evolution and distribution during friction surfacing

Friction surfacing (FS) is a solid state coating technology for similar and dissimilar metallic materials. The of the substrate with consumable material enabled due to frictional heat plastic deformation performed below materials' melting temperature. In this work, spatio-temporal temperature field during FS investigated within via combined experimental-numerical approach. study presents robust efficient thermal process model accounting contributions friction plasticity as input. geometry applied source dependent on deposit evolving flash. Extensive spatial measurements aluminum alloy combination are used in order identify required input parameters validate model. profiles varied parameters, such axial force, rotational speed travel well thickness backing plate systematically investigated, where experimental numerical results good agreement. Deviations particular associated possible scatter unknowns regarding exact position measurement modeling assumptions terms geometry. Overall, detailed comparisons illustrate that developed able obtain evolution distribution deposition acceptable accuracy wide range conditions.
