    摘要： In one aspect, a degradable apparatus is disclosed, including: an inner core with a first degradation rate in a downhole environment; an outer sheath disposed around an outer extent of the inner core with a second degradation rate less than the first degradation rate in the downhole environment. In another aspect, a method of temporarily sealing a downhole zone is disclosed, including: providing an inner core with a first degradation rate in a downhole environment; providing an outer sheath disposed around an outer extent of the inner core with a second degradation rate less than the first degradation rate in the downhole environment; sealing the downhole zone with the outer sheath; exposing the outer sheath to the downhole environment; and exposing the inner core to the downhole environment.

    摘要： A downhole assembly with controlled degradation including a body having a cavity therein and is formed from a first material having a first electrode potential. An insert is disposed in the cavity, the insert electrically coupled to the body and formed from a second material having a second electrode potential, with the first electrode potential being more negative than the second electrode potential.
