[0032] Example 1: Preparation method of a high-strength nano-medicine titanium-magnesium-silicon composite material

[0033]Ti powder, Mg particles (purity 99.6%), Si particles (purity 99.9%), V particles, Ag particles and TiC-SiC-VC-ZrC whisker particles in a molar ratio of 50:30:15:3: 1.5:0.5 uniformly mixed and prepared, bonded with isopropanol, then extruded on a press through a press die, and dried at room temperature for 5 minutes, so that the isopropanol evaporates and the adhesion between the particles disappears, Finally, a rod-shaped sample of D10mm×68mm was formed; the rod-shaped sample was put into the sheath, rotated repeatedly through the trident-shaped channel, and extruded 6 times, resulting in severe plastic deformation to obtain a titanium-magnesium-silicon composite material with nano-grain structure. The rod-shaped nanomaterials produced by the mold channel were washed and ultrasonically cleaned with distilled warm water, then washed with distilled warm wat...

Abstract

A preparation method of a high-strength degradable nano medical titanium-magnesium-silicon composite material is characterized in that the titanium-magnesium-silicon composite material provided with the nanograin structure comprises titanium, magnesium, silicon, vanadium and silver, meanwhile, titanium carbide-silicon carbide-vanadium carbide-zirconium carbide crystal whisker particles are added,the components of the composite material is represented by aTi-bMg-cSi-dV-eAg-f (TiC-SiC-VC-ZrC), wherein a=50,b=30, c=15, d=3, e=1.5, f=0.5 and a+b+c+d+e+f=100; particular materials are mixed and prepared according to a certain proportion, subjected to bonding through isopropyl alcohol and then directly subjected to powder pressing to form a blank, and the defect that toxic substances are generated during traditional metal smelting is overcome; the blank can be subjected to repeated squeezing fierce plastic deformation through a three-fork-shaped mold channel without being taken out, so thatthe nano high-strength material which is provided with the nanograin structure and is of a highly open structure is obtained; and in addition, magnesium can be automatically degraded after being implanted into a human body, and possibility is provided for bone tissue inward growing and healing of an implanted bone and a human body bone tissue.

Description

technical field [0001] The invention relates to a method for preparing a degradable nano-titanium-magnesium-silicon composite material with human affinity and mechanical properties close to that of human bone, specifically a novel titanium-magnesium-silicon composite material, which is applied in the field of medical implants. Background technique [0002] At present, metals and alloys used in medicine mainly include medical stainless steel, medical cobalt-based alloys, medical titanium and its alloys, medical magnesium alloys and other metals and alloys. Traditional medical metals and alloys are easy to corrode, and the dissolved ions may induce diseases and cause cell And tissue necrosis, poor mechanical properties, no biological activity, poor wear resistance, fatigue and fracture toughness are not ideal. Moreover, traditional implants have too high stiffness. Due to this stress shielding, large and rigid femoral prostheses are not recommended for patients with low bone d...
