TURBOMACHINE COMPONENT WITH SURFACE REPAIR

Abstract:

A component according to the disclosure may include: a rotatable body having an aperture therein for receiving one of a turbomachine shaft or a lathe chuck, wherein the aperture is oriented substantially axially relative to an axis of rotation of the rotatable body; and a flange coupled to and in direct axial contact with the body, the flange including a surface that extends axially relative to the axis of rotation of the body, wherein the surface of the flange comprises a matingly engageable face configured to contact an axially aligned surface during operation of the component, the matingly engageable face having a burnishing indentation thereon, wherein a surface roughness of the surface of the flange is less than a surface roughness of a remainder of the flange, and wherein a compressive stress of the surface of the flange is greater than a compressive stress of the remainder of the component.
