Abstract

The invention discloses a preparation method of a high-strength dense titanium alloy-ceramic biological composite material, and relates to the field of composite materials and medical materials. The preparation method comprises the following specific steps: titanium alloy powder and ceramic oxide powder are mixed according to a set proportion and then subjected to ball milling to obtain uniformly mixed titanium alloy-ceramic powder; and the uniformly mixed powder is dried, then is put in a spark plasma sintering (SPS) machine for sintering according to set parameters, and is cooled along with a furnace to obtain a product. The method solves such defects as weak wear resistance, low strength and difficult preparation in a traditional medical titanium alloy, has such advantages as simple flow, low consumption, environmental protection, easiness in operation and low cost, and is liable to realize industrial production.

Description

technical field [0001] The invention belongs to the technical field of metal-ceramic composite materials, and relates to a preparation method of high-strength and dense titanium alloy-ceramic biocomposite materials. Background technique [0002] With the aggravation of population aging and the advancement of scientific level, human beings' requirements and expectations for medical health continue to increase. According to statistics, there are more than 400 million disabled patients in the world today, and more than 90% of patients suffer from dental pain. Faced with such a severe challenge, countries all over the world have stepped up research and investment. According to predictions, in the next 10 to 15 years, industries related to biological implant materials will become one of the main pillars of the world. Manufacturing a non-toxic, low elastic modulus, high strength and good biocompatibility material is one of the main goals of current biomaterial technology. [00...
