ABSTRACT:
A method for asymmetrically consolidating a ring structure having a filamentary reinforcement embedded in a plasma sprayed deposited matrix is taught. The method involves fabricating a filament reinforced plasma sprayed deposit matrix structure and asymmetrically consolidating the structure. The asymmetric consolidation is accomplished by placing a thicker and/or stronger can surface on the outer portions of the ring structure and a thinner and/or weaker can structure on the inner and side surfaces of the reinforced ring structure. The HIPing of the reinforced ring structure with the asymmetric can results in a preferential compaction of the ring from the inside toward the outside and avoids the buckling of and damage to the reinforcement filaments on the outer portions of the structure.
