Problems solved by technology

[0003] The technical problem to be solved by the present invention is to solve the problem that the pores in the traditional production method of using pore-forming agents (ammonium bicarbonate, zinc stearate or polyvinyl alcohol) to prepare porous TC4 alloys are too small, and the pores are not connected during biomedical use. Pores are disordered, body fluids cannot run and other prominent problems

Abstract

The invention discloses a method for preparing an ordered porous TC4 alloy. TiH2 powder and Al-V alloy powder are mixed according to the standard ingredient proportion of the TC4 alloy, a template agent acetone solution is added, and high-energy ball milling is carried out; then vacuum hot pressing sintering is carried out, and finally the ordered porous TC4 alloy is obtained. According to the method, the template agent and the TiH2 powder, multiple ordered holes can be formed in the sintering process, holes in the alloy and the surface of the alloy can be effectively cleaned through hydrogenreleased by TiH2 in the dehydrogenation process, the good performance of the produced product is guaranteed, and the production process of the product is effectively shortened; and the pore morphologyof the titanium alloy is reasonably improved and optimized.

Description

technical field [0001] The invention belongs to the technical field of ordered porous titanium alloys, and specifically relates to the use of BHPA, TiH 2 A method for preparing ordered porous TC4 alloy by vacuum hot pressing sintering. Background technique [0002] TC4 alloy, namely Ti-6Al-4V alloy, is an α+β two-phase titanium alloy with low density, high specific strength, good heat and corrosion resistance, biocompatibility and good comprehensive mechanical properties. (α+β) is the most widely used two-phase titanium alloy. It was successfully developed by the American IIlinois Technology Institute in 1954. Its application rate accounts for 50% of the total output of titanium alloys and 95% of all titanium alloy processed parts. , has become a common titanium alloy in the world, and its porous products have been used as biological materials. In order to ensure the internal growth of new bone cell tissue and the good transmission of body fluids, it is required that the ma...
