Abstract

The invention discloses a titanium-based zirconia composite material medical implant and a 3D printing preparation method thereof, and relates to the technical field of metal laser selective melting (SLM). The method involves nano-ZrO 2 Ceramic powder is mixed with preset powder to get nano ZrO 2 Uniform composite powder with powder coating preset powder; preset powder and nano-ZrO 2 Ceramic powders are mixed under energy oscillation for breaking nano ZrO 2 Van der Waals force between ceramic powders; 3D printing after mixing uniform composite powders with titanium alloy powders. The method can have excellent human compatibility and comprehensive mechanical properties, and the material utilization rate is high, so that the parts obtained by the printing method have high precision, high density, and good corrosion and wear resistance. The predetermined powder may be a solid solution metal powder such as nickel, cobalt and titanium alloy. At the same time, by adjusting the nano-ZrO 2 The amount of ceramic powder can be used to design the microstructure of the implant surface, and parts with different mechanical properties can also be customized.

Description

technical field [0001] The invention relates to the technical field of metal laser selective melting (SLM), and in particular to a titanium-based zirconia composite material medical implant and a 3D printing preparation method thereof.
