Abstract
A thrust bearing comprises an electromagnetic stator with a stator surface and a rotor disk with a rotor surface facing the stator surface. The rotor disk comprises a radially inner portion made of a first material directly and exclusively connected to a radially outer portion made of a second material. The first material is a corrosion resistant metal or metal alloy and the second material is a ferromagnetic metal or metal alloy.
