Embodiment 1

[0034] Each component is weighed according to the molar concentration and mixed and stirred to form an electrolyte solution. The solvent is: deionized water; the solute is: sodium tetraborate (Na 2 B 4 o 7 10H 2 O) 0.15mol / L; suspended matter: calcium oxide (CaO) 0.05mol / L. XRD shows that the prepared micro-arc oxidation coating is mainly composed of rutile phase titanium dioxide and anatase phase titanium dioxide. EDS shows that the prepared micro-arc oxidation coating has an atomic percentage of calcium of about 2%, and the contact angle test shows that the prepared micro-arc oxidation coating The water contact angle of the coating is about 7°.

Embodiment 2

[0036] Each component is weighed according to the molar concentration and mixed and stirred to form an electrolyte solution. The solvent is: deionized water; the solute is: lithium tetraborate (Li 2 B 4 o 7 ) 0.15mol / L; suspended matter: strontium oxide (SrO) 0.05mol / L. XRD shows that the prepared micro-arc oxidation coating is mainly composed of rutile phase and anatase phase titanium dioxide, EDS shows that the prepared micro-arc oxidation coating has an atomic percentage of strontium of about 2%, and the contact angle test shows that the prepared micro-arc oxidation coating The layer water contact angle is about 6°.

Embodiment 3

[0038] Each component is weighed according to the molar concentration and mixed and stirred to form an electrolyte solution. The solvent is: deionized water; the solute is: sodium tetraborate (Na 2 B 4 o 7 10H 2 O) 0.15mol / L; suspended matter: strontium oxide (SrO) 0.025mol / L, calcium oxide (CaO) 0.025mol / L. XRD shows that the prepared micro-arc oxidation coating is mainly composed of rutile phase and anatase phase titanium dioxide. EDS shows that the prepared micro-arc oxidation coating has about 1 atomic percent of calcium element and about 1 atomic percent of strontium element. The sum of the atomic percentages of calcium and strontium is about 2%, and the contact angle test shows that the water contact angle of the prepared micro-arc oxidation coating is about 5°.

Abstract

The invention discloses an electrolyte for preparing a bioactive element contained porous membrane on a titanium metal surface through micro-arc oxidation, and belongs to the technical field of material surface modification. The micro-arc oxidation electrolyte is prepared from the following components of 0.10-0.15 mol / L of a tetraborate solution and 0.01-0.05 mol / L of a suspended material, whereintetraborate is one kind of lithium tetraborate, sodium tetraborate and potassium tetraborate, and the suspended material is one or more kinds of calcium oxide, strontium oxide and zinc oxide. Based on the electrolyte, a micro-arc oxidation experiment is adopted, titanium dioxide coatings prepared on the surface of titanium and the surface of a titanium alloy are provided with hierarchical structure formed by laminated-distributed micron-pores and randomly-distributed nano-pores, have high porosity and superhydrophilicity and contain one or more of bioactive elements of calcium, strontium andzinc, so that the problem that an existing micro-arc oxidation coating containing bioactive elements is insufficient in porosity, hole connectivity and hydrophilicity is effectively solved, the bioactivity of the titanium surface is effectively improved, and the electrolyte can be used for surface modification of bone replacement materials, in particular to dental implants.

Description

technical field [0001] The invention belongs to the technical field of surface modification of materials, and relates to a method for preparing titanium dioxide (TiO 2 ) coated micro-arc oxidation electrolyte. Background technique [0002] Titanium and titanium alloys are materials widely used in human hard tissue implants or substitutes such as dental implants, but the surface of titanium and titanium alloys lacks biological activity, so surface modification is required to improve the biological activity of titanium and titanium alloy surfaces. The main ways to improve the surface bioactivity of titanium and titanium alloys through surface modification are to construct surface microstructure, improve hydrophilicity and introduce bioactive elements. [0003] Micro-arc oxidation (also known as anodic spark oxidation or plasma electrolytic oxidation) is a surface modification technology suitable for titanium and titanium alloys. Through micro-arc oxidation treatment, an oxide...
