Abstract

The invention discloses a preparation method for a porous titanium-ceramic composite biological material, and relates to the field of porous composite materials and medical metal materials. The preparation method specifically comprises the technical steps of firstly, mixing an titanium alloy and nano-oxide ceramics according to a preset ratio, carrying out ball milling and then adding a pore forming agent and a binding agent for pressing; and then, sintering a sample in a high-temperature furnace according to a preset sintering parameter and carrying out furnace cooling so as to obtain a final product. The method has the advantages that the defects of poor mechanical property, low biocompatibility, no biological activity and the like of a traditional medical titanium alloy can be overcome, the process is simple, the consumption is low, the environment can be protected, the cost is low, the economical efficiency can be achieved, and industrial production can be realized easily.

Description

technical field [0001] The invention belongs to the technical field of porous composite materials and medical metal materials, and relates to a preparation method of titanium-ceramic composite biological porous materials.
