dc.description.abstractIn the present investigation, the microstructure evolution in Al 6061 coating deposited by friction surfacing on Al 2024 was studied in detail. The age hardening behaviour of the developed coating was also analysed. The Al 6061 tool material was solutionized prior to the coating process. The microstructural analysis revealed that, an ultra-fine grain microstructure could be achieved in coating by the coating process wherein the Al 2024 substrate has marginal modification in microstructure. Continuous dynamic recrystallization is identified as the mechanism of ultra-fine grain formation. Also, it was found that the process induced thermo-mechanical effect causing an increment in ageing kinetics. The enhanced ageing kinetics and formation of ultra- fine grains collectively improved the peak aged hardness of the friction surface coating, made using Al 6061. © 2022 Elsevier Ltd
