Abstract: Methods for forming a dual-phase magnetic component from an initial component comprising a non-magnetic austenite composition are provided. The method may include: forming a coating on a portion of the surface of the initial component to form a masked area while leaving an unmasked area thereon. Thereafter the initial component may be heated to a treatment temperature such that nitrogen diffuses out of the unmasked area of the initial component to transform the non-magnetic austenite composition to a magnetic phase in the unmasked area. Thereafter, the initial component may be cooled from the treatment temperature to form a dual-phase magnetic component having a magnetic region corresponding to the unmasked area and a non-magnetic region corresponding to the masked area.

Abstract: A method includes forming one or more oxide barrier layers on one or more protected portions of a magnetic, metallic body, and converting one or more unprotected portions of the magnetic, metallic body to a less magnetic material by exposing the magnetic metallic body having the one or more oxide barrier layers formed thereon to nitrogen. One or more protected portions of the magnetic, metallic body that are beneath the one or more oxide barrier layers are not converted to the less magnetic material. The method can be used to form one or more layers of a laminated electric motor.
