Abstract
A telescopic member includes, at least a central component and a barrier disposed within the central component, the barrier has a selectively tailorable dissolution rate curve and has structural properties enabling the containment of high pressure prior to structural failure of the barrier through dissolution.
Claims20
A telescopic member comprising:
- at least a central component;
- and
- a barrier disposed within the central component, the barrier having a selectively tailorable corrosion rate curve and having structural properties enabling the containment of high pressure prior to structural failure of the barrier through corrosion,
- wherein the barrier is constructed of a powder compact that comprises:
- a substantially-continuous, cellular nanomatrix comprising a nanomatrix material;
- a plurality of dispersed particles comprising a particle core material that comprises Mg, Al, Zn or Mn, or a combination thereof, dispersed in the cellular nanomatrix;
- and
- a solid state bond layer extending throughout the cellular nanomatrix between the dispersed particles.
