Abstract[German]
Die Erfindung betrifft ein Verfahren (1) zum Herstellen eines Kolbens (2) mit einem Kernkörper (3) und wenigstens einem Träger (4). In dem Verfahren (1) werden der Kernkörper (3) und der wenigstens eine Träger (4) über eine intermetallische Alfinier-Schicht miteinander verbunden. Die Erfindung betrifft auch einen in dem Verfahren (1) hergestellten Kolben (2) und eine thermoakustische Wärmepumpe mit dem Kolben (2).[English]
The invention relates to a method (1) for producing a piston (2) having a core body (3) and at least one support (4). In the method (1), the core body (3) and the at least one support (4) are interconnected via an intermetallic aluminum finishing layer. The invention also relates to a piston (2) produced in the method (1) and to a thermoacoustic heat pump comprising the piston (2).[French]
