摘要:
A metallic component is bounded by at least one peripheral edge. The component includes at least one elongated treated zone having a length substantially greater than its width. This treated zone is spaced away from and disposed generally parallel to the peripheral edge of the component and the entire thickness of the component within the treated zone is in a state of residual compressive stress. Crack growth from the edge due to fatigue or damage is resisted.

摘要:
A method of evaluating the condition of a rolling burnishing element (14) includes moving a burnishing element (14) having an unknown condition against a surface in a preselected test pattern (T1); while moving the burnishing element (14), recording at least one test force profile (30) representative of a force acting on the burnishing element (14) in at least one dimension; and comparing the at least one test force profile (30) to at least one baseline force profile (28) to determine a deviation of the condition of the second burnishing element (14) from a baseline condition.
摘要:
An apparatus for process control of a burnishing process including a body having a first end (14) and a second end (16), at least one process control coupon (100), and structure for attaching the process control coupon (100) to the body. At least one edge (101, 102, 103, 104) of the process control coupon (100) is clamped along the entire length thereof during burnishing. A method of process control for burnishing of components comprising selecting at least one process control coupon (100), selecting an apparatus (10) for holding the process control coupon(s) (100), attaching the process control coupon(s) (100) to the apparatus (10), selecting a region (301) on the surface (121, 122) of the process control coupon(s) (100) for burnishing, burnishing a patch (303) on the selected region (301) using a burnishing process, and, measuring at least one physical parameter at a selected location of the process control coupon(s) (100) after burnishing.
