Kind Code:
A3
Abstract:
A method of making a selectively corrodible article is disclosed. The method includes forming a powder comprising a plurality of metallic powder particles, each metallic powder particle comprising a nanoscale metallic coating layer disposed on a particle core. The method also includes forming a powder compact of the powder particles, wherein the powder particles are substantially elongated in a predetermined direction to form substantially elongated powder particles. In one embodiment, forming the powder compact includes compacting the powder particles into a billet, and forming the billet to provide the powder compact of the powder particles, wherein the powder particles are substantially elongated in a predetermined direction to form substantially elongated powder particles.
