Zusammenfassung:	An armature (68) for a selectively engageable and disengageable coupling (20) and a method of making the armature are provided. The armature includes a substantially annular body (80) that is disposed about a first axis (28). The body may be formed by stamping or fine-blanking. One side of the body is hardened through a nitriding process. A grinding wheel is then applied at an angle to the same side of the body along a diametrical line of the body extending perpendicular to the first axis. As a result, the body is configured so that the thickness of the body varies along each cross-section taken along the line from a minimum thickness at the innermost portion of the cross-section to a maximum thickness at the outermost portion of the cross-section. The inventive armature reduces galling, and the resulting noise, that occur during burnishing of the couplings incorporating the armature.
