preparation example Construction

[0047] The preparation method of the micro-nanoporous structure on the surface of Zr-based metallic glass comprises the following specific steps: putting the three electrodes into the choline chloride-thiourea eutectic solvent, adjusting the voltage of the working electrode, the temperature of the electrolyte and the voltage output time, applying Voltage to prepare micro-nano porous structure.

[0048] Among them, the three electrodes are: working electrode: flake Zr-based metallic glass, reference electrode: Ag / AgCl, and counter electrode is graphite electrode.

[0049] Zr-based metallic glass is composed of five elements: Zr, Cu, Ni, Ti, and Al, and the mass percentage of each element is Zr 50-65%, Cu 15-25%, Ni 10-15%, Ti 5-10%, Al 5-10%.

[0050] Before putting the Zr-based metallic glass substrate into the choline chloride-thiourea deep eutectic solvent as the working electrode, it is pretreated, first degreasing, then cleaning, then pickling, then cleaning, and then usi...

Embodiment 1

[0052] Put the working electrode, reference electrode and counter electrode into the electrolyte, when the voltage is 2.5V (vs Ag / AgCl), the time is 1.5h, and the temperature is 75°C, a micro-nano porous structure is formed on the surface of the Zr-based metallic glass .

[0053] Such as figure 1 As shown, the micro-nano porous structure obtained on the surface of the Zr-based metallic glass in this example has a pore diameter of 0.3-0.8 μm.

Embodiment 2

[0055] Put the working electrode, reference electrode and counter electrode into the electrolyte. When the voltage is 3.5V (vs Ag / AgCl), the time is 2h, and the temperature is 85°C, a micro-nanoporous structure is formed on the surface of the Zr-based metallic glass.

[0056] Such as figure 2 As shown, the micro-nano porous structure obtained on the surface of the Zr-based metallic glass in this example has a pore diameter of 0.2-0.7 μm.

Abstract

The invention provides Zr-based metal glass as well as a preparation method and application thereof, and belongs to the technical field of metastable material surface treatment. The surface of the Zr-based metal glass has a micro-nano porous structure, and the pore diameter of the micro-nano porous structure is 0.2-0.8 microns; and according to the preparation method, a micro-nano porous structure is prepared on the surface of Zr-based metal glass in a choline chloride-thiourea eutectic solvent through an electrochemical selective dissolution method. The pore diameter of the porous structure synthesized by the method is 0.2-0.8 microns, and the synthesis of the structure can effectively improve the forming ability of the material in a hydroxyapatite layer in simulated body fluid and improve the biocompatibility of the material.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of metastable materials, and in particular relates to a Zr-based metallic glass and its preparation method and application. Background technique [0002] Compared with metallic glasses of other systems, Zr-based metallic glasses have a wider supercooled liquid phase region, which means that Zr-based metallic glasses are easier to prepare and easier to industrialize; in addition, Zr-based metallic glasses also have higher biomechanical matching The density and modulus of elasticity are closer to those of human bones, and can prevent bone resorption and atrophy after being implanted in the human body. Therefore, Zr-based metallic glasses have attracted the attention of scholars at home and abroad as new medical biomaterials. [0003] However, the surface of Zr-based metallic glass is biologically inert, and it is difficult to form a good osseointegration with the target after implantation...
