The repair of weapons systems often involves powder deposition or some other means of applying metals or metal alloys to a component and providing a metallurgical bond between the original metal matrix and the applied metal. These repair technologies are termed additive because a new metal surface is being added to the damaged matrix material. It is imperative that the repaired part perform as well as the original. These additive processes can serve as alternatives to plating processes, but are considered line-of-sight technologies and might not be applicable to parts with complex geometries. SERDP and ESTCP are exploring where and how these additive techniques can be applied and demonstrate equivalent or improved overall performance.
