Problems solved by technology

Although titanium is rich in reserves in nature, it is difficult to extract, and titanium metal is more active at high temperature, and it is easily oxidized during smelting, which limits the application of titanium metal. Therefore, titanium metal was first used in aerospace and marine engineering and other fields. For example, the application of titanium metal as a structural material on aircraft, satellites, and space shuttles, or corrosion-resistant materials applied to ships, submarines, etc.

preparation example Construction

[0019] According to one aspect of the present invention, there is provided a method for preparing a bacteriostatic titanium gold product, including the following steps:

[0020] S1: Provide a titanium gold product, which has a surface of titanium metal;

[0021] S2: Clean the surface of titanium metal;

[0022] S3: Using nitrogen as the reaction gas, argon as the working gas, using the surface of titanium as the substrate, and using titanium dioxide as the target material, perform RF magnetron sputtering treatment on the surface of the titanium metal to form formation on the surface of the titanium metal Titanium oxynitride film.

[0023] Titanium metal includes industrial pure titanium and titanium alloys, such as TA1, TA2, TA3, Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and so on.

[0024] In some embodiments, in step S1, acetone is used to clean the surfaces of stainless steel circular plates, pure aluminum circular plates, and titanium metal circular plates to wash away impurities and oil...

Embodiment 1

[0030] A thin film of titanium oxynitride is formed on the inner surface of the titanium pan. The titanium pot is heated to 350℃, N 2 The flow rate is 2.5 sccm, the flow rate of Ar is 90 sccm, the power of RF magnetron sputtering is 300W, and the treatment time of RF magnetron sputtering is 5h. Under this process condition, the thickness of the oxynitride formed on the surface of the titanium metal reaches about 0.8 μm.

Embodiment 2

[0032] A thin film of titanium oxynitride is formed on the inner surface of the titanium pan. The titanium pot is heated to 375℃, N 2 The flow rate is 2.75 sccm, the flow rate of Ar is 95 sccm, the power of RF magnetron sputtering is 300W, and the treatment time of RF magnetron sputtering is 6h. Under this process condition, the thickness of the oxynitride formed on the surface of the titanium metal reaches about 1.2 μm.

Abstract

The invention provides a preparation method of an antibacterial titanium product. The preparation method comprises the following steps that S1, a titanium product is provided, wherein the titanium product is provided with a titanium metal surface; S2, the titanium metal surface is cleaned; and S3, nitrogen serves as reaction gas, argon serves as working gas, the titanium metal surface serves as asubstrate, titanium dioxide serves as a target material, radio frequency magnetron sputtering treatment is conducted on the titanium metal surface, and a titanium oxynitride film is formed on the titanium metal surface. According to the method, the titanium oxynitride film can be formed on the titanium metal surface of the titanium product, the nitrogen element is introduced into a crystal latticeor a crystal boundary of titanium dioxide, the impurity energy level and the defect energy level are introduced into a titanium dioxide forbidden band gap, the excitation energy borne by the titaniumdioxide forbidden band gap is reduced, the band gap of titanium dioxide is reduced, the light absorption range of titanium dioxide is widened, and the antibacterial effect of the titanium product isimproved.

Description

Technical field [0001] The invention relates to the field of titanium gold products, in particular to a method for forming a nitrogen oxide layer with antibacterial function on the surface of titanium gold products. Background technique [0002] Many products are often used in daily life, such as pots, cups, utensils, door handles, sports equipment, etc. When these products are exposed to the air, bacteria will grow on the surface. With the improvement of people's living standards, the quality requirements for products in daily life are increasing day by day. [0003] The advantages of titanium metal are light weight, high strength and strong corrosion resistance. Although titanium is abundant in nature, it is difficult to extract. Titanium is more active at high temperatures and is easily oxidized during smelting, which limits the application of titanium. Therefore, titanium was first used in aerospace and marine engineering. For example, titanium is used as a structural materi...
