Resumo

A series of similar joints made from Al2017A aluminum alloy were produced through rotary friction welding, with localized reinforcement provided by alumina (Al₂O₃) particles, a ceramic known for its high hardness and extensive use in metal–matrix composites. These particles were placed at the weld interface by filling drilled holes of different diameters in the fixed component, allowing the influence of varying volume fractions on joint behavior to be examined. Tests of tensile strength and microhardness indicated that adding Al₂O₃ leads to a noticeable improvement in the mechanical performance of the welded joints when compared with those lacking ceramic reinforcement.
