Aluminum alloy components for casting in Al- or Al/Mg based light metal alloys, especially cylinder liners for engine blocks, have a conditioning layer and an electroplated coating of zinc or zinc alloy over this : Independent claims are included for: (A) a method for making composite article by casting Al alloy components in light metal alloys; and (B) engine blocks with integrally cast cylinder liners produced using the method. Die Erfindung betrifft ein Bauteil aus Al-Legierung zum Eingießen in eine Leichtmetalllegierung auf Al- oder Al/Mg-Basis mit einer Konditionierungsbeschichtung mit einer niedrig-schmelzenden Metallbeschichtung, wobei die Metallbeschichtung aus galvanisch abgeschiedenem Zn oder einer Zn-Legierung besteht und unmittelbar ohne Zwischenschichten auf die Oberfläche des Bauteils aufgetragen wird.
