FERROUS DISINTEGRABLE POWDER COMPACT, METHOD OF MAKING AND ARTICLE OF SAME

摘要

A process for preparing a disintegrable powder compact, the process comprises: combining: a primary particle comprising a ferrous alloy which comprises carbon; and a secondary particle to form a composition; compacting the composition to form a preform; and sintering the preform to form the disintegrable powder compact by forming a matrix from one of the primary particle or the secondary particle; and forming a plurality of dispersed particles from the other of the primary particle or the secondary particle, wherein the dispersed particles are dispersed in the matrix, the disintegrable powder compact is configured to disintegrate in response to contact with a disintegration fluid, and the primary particle and secondary particle have different standard electrode potentials.
