PREPARATION METHOD OF POROUS IMPLANT AND POROUS IMPLANT PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2013/047998
Kind Code:
A3
Abstract:
The present invention relates to a preparation method of a medical porous implant and a porous implant prepared thereby, and more specifically, to a preparation method of a porous implant and a porous implant prepared thereby, wherein the preparation method comprises: a filling step of filling a material comprising a metal powder and a ceramic powder into a mold; and a sintering step of applying 100-2,000 kgf/cm2 of pressure to the material filled in the mold and simultaneously generating 500-2000 A of current and 3-7 V of voltage using a spark plasma sintering device so as to allow current to flow throughthe material, thereby sintering the material at 800-1,400 ℃. The porous implant is harmless to the human body, and can be prepared within a short time at low temperatures, thereby reducing manufacturing costs.
