METHOD FOR PRODUCING BIOCOMPATIBLE POROUS ALLOY BASED ON TITANIUM NICKELIDE Russian patent published in 2023 - IPC C22C1/47 C22C1/08 C22C19/03 C22C14/00 B22F3/16 A61F2/02 

Abstract RU 2796898 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to technology of obtaining porous metallic materials by diffusion sintering and can be used in medical implantology. A biocompatible porous alloy is obtained by double sintering of a mixture containing titanium nickelide powder and the addition of 0.8-1.2% silver nanopowder by weight over a portion of titanium nickelide powder. The first sintering is carried out in a graphite crucible at a temperature of 1220±5°C within 30±5 minutes, the second sintering is carried out at a temperature of 1265±5° C within 30±5 minutes on a tungsten substrate, followed by cooling in an oven.

EFFECT: increased cytocompatibility while maintaining mechanical strength by reducing the size of the grains.
