Abstract

The invention discloses a light metal foaming material and a preparation method thereof, and relates to the technical field of new materials. The preparation method comprises the following steps: firstly, carrying out evaporation deposition on titanium alloy and hydroxyapatite for primary foaming, and then carrying out hot isostatic pressing treatment on a titanium alloy-hydroxyapatite compound obtained after primary foaming; during vapor deposition, transversely spraying out inert gas firstly so that the titanium alloy is changed into metal smoke, then longitudinally spraying out inert gas with a high flow speed, and meanwhile adding hydroxyapatite into a system; then under the action of longitudinal hydroxyapatite smoke motion, directly forming a spherical core-shell titanium alloy-hydroxyapatite compound of the titanium alloy coated with hydroxyapatite on an upper low-temperature plate; and during hot isostatic pressing treatment, and directly preparing light foamed metal with the porosity ranging from 60 to 80 percent by using the inert gas and oxygen as pressurizing media. The prepared light metal foaming material is 60 to 80 percent in porosity, and is very suitable for serving as an implant to be implanted into a bone.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a lightweight metal foam material and a preparation method thereof. Background technique [0002] As a metal material for medical implants, it needs to have a certain impact resistance after implantation to ensure that it can withstand various forces after implantation in the human body. For implants, the material should also have a certain fatigue strength and high wear resistance to meet the needs of long-term use. Abrasion resistance of medical materials is an important indicator for long-term implantable materials. Poor wear resistance can lead to adverse consequences such as spit, infection, and loosening of the implant material, eventually leading to damage to the implant. [0003] When the metal is implanted into the human body, due to the movement of the human body, it will inevitably interact with the surrounding bone tissue, and these actions include tension, compression ...
