Steel-aluminum　laminates　show　promise　in　industrial　manufacturing,　yet　their　utilization　is　limited　by　unstable　interface　bonding.　This　study　investigates　the　influence　of　laser　texturing　on　the　interface　bonding　properties　of　DP600/AA1060　obtained　through　co-extrusion.　White-light　interference　profilometry　(WLIP)　and　MATLAB　algorithms　are　used　to　quantify　different　surfaces.　A　model　is　established　to　predict　the　shear　load　with　different　process　angles.　Furthermore,　energy　dispersive　spectroscopy　(EDS),　scanning　electron　microscope　(SEM)　and　X-ray　diffraction　(XRD)　are　utilized　to　examine　the　microstructure　of　interface　fractures　and　DP600/AA1060　alloys.　Notably,　the　laser　texturing　process　(LTP)　significantly　enhances　the　interface　bonding　strength　of　the　DP600/AA1060,　yielding　a　37%　increase　in　maximum　shear　strength　compared　to　the　original　sample.　The　prediction　holds　true　for　the　process　angle　in　the　range　of　0°–45°　but　failed　between　45°　and　90°　due　to　the　occurrence　of　tensile/compressive　stress　in　the　laser-textured　area,　leading　to　unstable　bonding　caused　by　oxides　and　alloy　particles.　However,　the　laser-textured　surface　of　DP600　enhances　mechanical　interlocking　and　increases　the　number　of　micro-protrusions,　thereby　strengthening　the　interface　bonding　and　improving　the　mechanical　properties　of　co-extruded　laminates.　©　2024　The　Authors
