ABSTRACT:
A retaining ring for an engine gasket has an annular section with convex upper and lower surfaces. The ring is formed from a homogeneous composite powdered metal with multiple density material zones. The composite powdered metal retaining ring has numerous advantages. It is possible to design and manufacture a ring having a desired yield strength in both the vertical and hoop directions, wherein the stiffness along a particular axis may be selectively variable as a function of seal loading. The multiple density zones may be provided by layers of material. In other aspects of the invention, the powdered metal may be primarily titanium with trace elements of the composite powdered metal providing lubrication to reduce the coefficient of friction of the composite metal at the ring's outer surface.
