Abstract: A method for inspecting a metallic component comprises providing an inspection standard having an eddy current signature substantially similar to an eddy current signature of the metallic component, wherein the inspection standard body is fabricated from a non-metallic material. The method also comprises inspecting the metallic component with an eddy current probe with reference to the inspection standard.

Abstract: A bearing element having a metallic body with a bearing contact curved surface portion, at least one laser shock peened surface encompassing at least a portion of the contact surface portion, and a region having deep compressive residual stresses imparted by laser shock peening (LSP) extending into the body from the laser shock peened surface. The present invention may be used for rolling elements such as ball bearing elements or elongated roller elements and for static elements such as races which may be singular or split and may have circumferentially spaced oil feed passages radially disposed therethrough.

Abstract: An ultrasonic fixture assembly for holding multiple ultrasonic transducers includes a mounting support rod for attaching the fixture assembly to a manipulator of a ultrasonic inspection system. A plurality of transducer mounting blocks may be mounted to the support rod by an elongated mounting bar or a single transverse mounting block may be mounted to the support rod. Each of the transducer mounting blocks will have a channel formed therein for slidably receiving an ultrasonic transducer or if a single transverse mounting block is used a plurality of channels will be formed through the mounting block. A central channel or a central transducer mounting block is provided for receiving and retaining a longitudinal wave type ultrasonic transducer and other channels or transducer mounting blocks disposed on either side of the longitudinal transducer are formed to hold shearwave type transducers.

Abstract: An apparatus for the inspection of a stack of cylindrical objects such as roller bearings, uses an eddy current probe. The probe is positioned at an angle with respect to the surfaces of the objects in order to achieve an acceptable signal and then the objects are rotated while the probe is advanced along them to fully scan the surfaces.

Abstract: An invention is disclosed which supports an eddy curent probe at a predetermined distance from a surface to be scanned. In another embodiment, the probe is scanned by rotation about an axis and along an arc of predetermined length and position.

Abstract: In one form of the present invention, an apparatus for tightening a bolt stores information relating to an allowable relationship between change in bolt length and torque. A wrench applies a time changing torque to the bolt, the change in bolt length is measured by timing a traveling acoustic pulse in the bolt, and comparison means ascertains whether the torque-length behavior of the bolt exhibits the allowable relationship.
