specific Embodiment approach 1

[0012] Embodiment 1: A copper-containing antibacterial titanium alloy in this embodiment is made by adding 1% to 30% copper in mass percentage to pure titanium or titanium alloy.

[0013] Pure titanium in this embodiment refers to titanium with a titanium content ≥ 99.9% (mass).

[0014] In the copper-containing antibacterial titanium alloy of this embodiment, copper element is added to pure titanium or titanium alloy to form an antibacterial phase in the titanium alloy. When the copper-containing antibacterial titanium alloy is in contact with bacterial liquid or other liquids, Cu ions will be dissolved, and the dissolved Cu ions have a bactericidal effect, thereby achieving a bactericidal and antibacterial effect. The copper-containing antibacterial titanium alloy of this embodiment is to make the whole titanium alloy have antibacterial properties through alloying treatment, that is, the integral antibacterial titanium alloy. It has good antibacterial properties even after ...

specific Embodiment approach 2

[0015] Embodiment 2: This embodiment differs from Embodiment 1 in that the titanium alloy is an α-type titanium alloy, a β-type titanium alloy or an α+β-type titanium alloy; other aspects are the same as Embodiment 1.

specific Embodiment approach 3

[0016] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the titanium alloy is Ti-6Al-4V, Ti-6Al-7Nb, Ti-5Al-2.5Fe, Ti-12Mo-6Zr-2Fe, Ti-15Mo-5Zr-3Al, Ti-15Mo-3Nb-3O, Ti-15Zr-4Nb-2Ta-0.2Pd, Ti-15Zr-4Nb-2Ta-0.2Pd, Ti-13Nb-13Zr or Ti-Nb-Ta- Zr. Others are the same as the first embodiment.

Abstract

The invention discloses a copper-bearing antibacterial titanium alloy and a preparation method thereof, and relates to an antibacterial titanium alloy and a preparation method thereof. In the invention, the problems of easy recession or loss and poor long-term effectiveness of a surface antibacterial layer of the current antibacterial titanium or titanium alloy can be solved. The copper-bearing antibacterial titanium alloy disclosed by the invention is prepared by adding 1-3% by weight of copper to pure titanium or titanium alloy. The method comprises the following steps of: weighing pure copper powder and titanium material powder; under the protection of gas or liquid, adding the pure copper powder and the titanium material powder to a ball mill to be milled to obtain powder; adding the powder to a mould; hot pressing and sintering in vacuum to obtain the copper-bearing antibacterial titanium alloy. The copper-bearing antibacterial titanium alloy disclosed by the invention is an integral antibacterial titanium alloy, has long-term effectiveness and can be used in the medical field or the field of articles for daily life.

Description

technical field [0001] The invention relates to an antibacterial titanium alloy and a preparation method thereof. Background technique [0002] Titanium alloys are widely used in medicine, such as artificial joints in surgery. Titanium and titanium alloys are more widely used in dentistry, such as artificial tooth roots, orthodontic wire, crown bridges for molars, metal gums, trays, and jawbone implants. However, the following problems have been found in the use of titanium alloys for medical treatment: [0003] 1) Surgical artificial prosthesis, although aseptic operation is used during the operation and antibiotics are used, the infection of titanium and titanium alloy implants still causes a high morbidity rate, which has long been a thorny problem for medical staff question. The data show that the infection rate after total pulp joint replacement is 0.1%-1%; the infection rate of the total knee joint is 1%-4%; the infection rate of the total elbow joint is 4%-47%; the...
