ABSTRACT:
A method of manufacturing a corrosion resistant rotor assembly including heating the core of the rotor assembly which is made of a stack of thin steel laminations to a temperature sufficient so as to cause at least some oxidation of the core and the quenching the core in a temperature controlled bath of suitable oil so as to form a tough, corrosion resistant surface on the exposed surfaces of the rotor assembly.
