Method for preparing medical degradable open-cell foam zinc by powder metallurgy method

摘要: The invention discloses a method for preparing medical degradable open-cell foam zinc by powder metallurgy method. comprises the following steps of (1) drying and mixing apore-forming agent; (2) adding alcohol; (3) filling into mold compression molding; (4) placing in sintering furnace, carrying out vacuum or covering graphite sintering, cooling along with furnace; (5) sintered material water, dissolving pore-forming agent taking remaining material. According to disclosed invention, size porosity pore diameter can be controlled; mechanical strength property sample controlled temperature time, compressive prepared is higher than that human cancellous bone, elastic modulus matched requirements implanted materials met.
