摘要： A metallic article with improved fatigue performance and resistance to corrosive attack and stress corrosion cracking is produced by treating a first area of a metallic article with a first surface treatment that induces a specified amount of cold work. A second, sacrificial area of the metallic article in electrical communication with the first area is treated with a second surface treatment that induces an amount of cold work higher than that of the first surface treatment. Due to the differences in cold work resulting from the different surface treatments, the second area of the metallic article is less noble than the first area and is therefore more susceptible to corrosive attack. As a result, the second sacrificial area will preferentially corrode leaving the first area protected from corrosive attack. Compressive residual stresses induced in the surface of the metallic article through the surface treatments improve the fatigue performance and resistance to stress corrosion cracking.

摘要： A surface treatment element having a textured surface with a plurality of deforming features is pressed against the surface of an article to induce deep and shallow layers of compressive residual stress to form a continuous layer of compressive residual stress extending from the surface to a depth beneath the surface. A method whereby a surface treatment apparatus is pressed into the surface of the apparatus to cause Hertzian loading thereby inducing a deep, high magnitude compressive residual stress below the surface. The deforming features of the surface treatment element cause the lateral displacement of material on the surface of the article thereby cold working the surface and providing a more shallow layer of compressive residual stress at the surface.

摘要： The burnishing method and apparatus for implementing the method of the present invention utilizes a single-point burnishing process to provide deep compression with a minimal amount of cold working and surface hardening. In particular, the area to be burnished along the surface of a workpiece is defined and a freely rotating burnishing ball is forced against the surface of the workpiece to produce a zone of deformation having a deep layer of compression within the surface. The burnishing ball is then rolled over the surface in a substantially nonoverlapping pattern. A preferred embodiment of the burnishing apparatus for implementing the burnishing method comprises a socket having a tip member incorporating a ball seat, a burnishing ball disposed within the ball seat, a rod member integrally formed with the tip member; and a socket support for supporting the socket on a conventional tool holder. The socket is provided with means for directing lubrication fluid from a reservoir to the ball seat to permit the burnishing ball to freely rotate and for directing a predetermined amount of lubrication fluid to the surface of the workpiece.

摘要： A method of inducing compressive residual stress of blading members integrally formed with a rotor. The method includes using a caliper-type burnishing tool such that the caliper arms of the tool are contoured and oriented for placing the burnishing elements on opposite sides of the blading member to be treated. The blading member is burnished to introduce a pre-determined pattern of residual compressive stresses in a selected area of the blade.
