    Abstract: Method for Simultaneous Peening and Smoothing A method for simultaneously shot peening and smoothing includes use of relatively large, smooth, hard, spherical steel shot having a substantially uniform diameter in the range 1-2.5 mm. Titanium workpieces are provided in one step with a compressive stress layer of the order of 0.13 mm. and a surface finish of better than 15 x 10 6 inch AA, compared to conventional peened finishes of the order of 40 x 10-6 inch AA. Surface finish and peening intensity are interrelated and dependent on shot diameter, mass, velocity, and energy within relatively small limits. The shot diameter is uniform within ? 0.05 mm; the shot impact velocity is uniform within ? 4 percent or less, in the range 1.4-12 m/s. The method is also applied to the simultaneous densification and smoothing of overlay coatings on workpieces, such as those deposited by physical vapor deposition and plasma spraying. Usually heat treatment follows the peening step.

    Abstract: Shot Peening Apparatus In apparatus for shot peening, gravity is used to accelerate uniform sized steel shot, and thereby impart a combination of good surface finish and uniform compressive stresses to workpieces. It is especially useful for finishing gas turbine airfoils. Shot is introduced into the peening enclosure (28) through a gate (40) at near zero velocity. It is then accelerated along a streamline (31) toward the workpiece (18) with uniform velocity. The workpiece, positioned along the streamline, can be manipulated in three rotational modes: oscillatory rotation to uniformly peen contoured surfaces of a workpiece, periodic incremental rotation to peen different sides of a workpiece; and, tilting motion to enable peening of shoulders (22). The apparatus is especially suited to peening fragile workpieces such as gas turbine airfoils (18). A diverter plate (44) intercepts the shot stream at times when repositioning of a fragile workpiece is undertaken. Thus, possibly damaging impacts are avoided and steady state operation is able to be promptly resumed.

    Abstract: A method of processing an article includes heating the article in an atmosphere substantially free of oxygen to an oxidation temperature within a predetermined temperature range. The article includes a substrate and a bond coat disposed on the substrate. A partial pressure of oxygen is then established within the atmosphere after heating to the oxidation temperature. At least a portion of the bond coat oxidizes in the partial pressure of oxygen at the oxidation temperature to form a desired type of oxide to the substantial exclusion of forming other types of oxides. A ceramic coating is then deposited on the oxide.

    Abstract: A physical vapor deposition apparatus includes first and second chambers. A first directed vapor deposition crucible is at least partially within the first chamber for presenting a first source material to be deposited on a work piece. A second directed vapor deposition crucible is at least partially within the second chamber for presenting a second, different source material to be deposited as a second coating on the work piece. At least one of the materials may be deposited as a coating.

    Abstract: Shot peening of thin edges of workpieces which are subject to deformation damage by direct impacts is accomplished by rotating the workpiece edge near centerline through a particular angle measured from the nor mal to the shot streamline. The angle is sufficient to cause oblique blows on the centerline of the edge, but insufficient to cause direct impacts. Compressive stresses by the oblique blows provide residual compressive stresses along the centerline to the desired depth. The angle is calcuable from the edge radius, the depth of stressing desired at the centerline, and the depth of stressing produced by shot at a reference location. Oscillatory rotation is preferably used to obtain even peening.
