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： A method of pre-stressing a component such as a turbine blade (52) comprises providing an electrically conducting sheet (66) adjacent to a component (52) within a fluid medium (56). An electrical discharge is supplied from an electrical discharge circuit (58) to the electrically conducting sheet (66) to produce vaporisation there of (66). The vaporisation of the electrically conducting sheet (66) produces a planar pressure pulse in the medium (56) adjacent to the component (52). The planar pressure pulse impacts on a surface of the component (52) to produce a region of residual compressive stress within the component (52).

摘要： A method for obtaining enhanced fatigue strength in welded metal joints and -components comprising a weld toe (9) subjected to cold working such that a visible and/or measurable indentation at the weld toe (9) is produced. The cold working is carried out by means of a power driven hammer head, which has a slightly convex, elongated contact surface (3) in the length direction for contact with the weld toe (9) . Hereby,' the geometry of the weld toe (9) is strongly improved at the same time as residual stresses after the welding are eliminated and advantageous compressive stresses are established.

摘要： The present invention is a novel method of reducing tensile zones in the surface of a part comprising the steps of selecting a region of the part to be treated and programming a control unit (132) of a burnishing apparatus (100) to perform a burnishing operation, the burnishing operation being performed such that the density of burnishing and the magnitude of compression are varied to reduce the high tensile stress along the boundaries of the selected region. In a preferred embodiment of the invention, the burnishing operation induces a deep layer of compression within the surface of the part with a minimal amount of cold working and surface hardening.

摘要： Tooling and a method of employing tooling (90, 130) to produce beneficial stress waves in a substrate (132) to provide high fatigue life structures. Stress waves (159, 152) are provided to work a substrate, causing dimples (170) in the workpiece, along a uniform pressure profile in the workpiece. By use of the method, uniform beneficial residual stress is provided at surface and midplane apertures in a workpiece, so as to improve overall fatigue life. An improved tool shape (92) is described, having a smooth curve, rather than a flat punch. Also, the use of a consumable wafer (W) provides additional uniform stress profile benefits.
