Abstract

Die vorliegende Erfindung betrifft einen Rotor (1) für eine Ladeeinrichtung, insbesondere für einen Abgasturbolader, mit einer ein Turbinenrad (2) und ein Verdichterrad tragenden Welle (3). Erfindungswesentlich ist dabei, dass zur Anbindung insbesondere des Turbinenrades (2) an die Welle (3) zumindest zwischen diesem und der Welle (3) wenigstens ein poröses metallisches oder keramisches Zwischenstück (4) vorgesehen ist, das über einen Infiltrationsprozess mit dem Turbinenrad (2) und/oder der Welle (3) verbunden ist.
