Problems solved by technology

However, because silver is a precious metal, the cost of stainless steel products mixed with silver is too high. Although it still has antibacterial properties after wear and tear, its use is limited due to the high cost, and stainless steel products only need antibacterial on the surface, and the in

Embodiment 1

[0019] The structural schematic diagram of the surface antibacterial and wear-resistant stainless steel product of the present invention is as follows: figure 1 , 2 As shown, a stainless steel base material (1) and several TiAgN coating layers (2) are included, and the TiN and TiAgN coating layers (2) are plated on the outside of the stainless steel base material (1).

[0020] The above-mentioned several TiN and TiAgN coating layers (2) may be one layer or more than one layer. In this embodiment, the TiN and TiAgN coating layers (2) may be four layers.

[0021] The silver and titanium components contained in the above-mentioned TiN and TiAgN coating layers (2) change in steps, that is, the inner coating layer contains low silver content and high titanium content, and the outer coating layer contains high silver content and low titanium content.

[0022] The silver content of the innermost coating layer may be 0-0.3%, and the silver content of the outermost coating layer may ...

Embodiment 2

[0028] The structure of the surface antibacterial and wear-resistant stainless steel product of the present invention is the same as that of Example 1, except that the TiN and TiAgN coating layers (2) can be 5 layers. The silver content of the innermost coating layer may be 0.15%, and the silver content of the outermost coating layer may be 15%. The thickness of the innermost coating layer may be 0.05um, and the thickness of the outermost coating layer may be 5um.

[0029] The preparation method of the surface antibacterial and wear-resistant stainless steel product of the present invention adopts the magnetron sputtering method. Filling with nitrogen can generate TiAgN and TiN.

[0030] Due to the different sputtering yields of different elements, the sputtering threshold is higher for titanium and lower for silver. Therefore, multiple titanium palladiums are arranged in the sputtering furnace cavity to increase the sputtering yield of titanium. In addition, the sputtering...

Embodiment 3

[0033] The structure of the surface antibacterial and wear-resistant stainless steel product of the present invention is the same as that of Example 1, except that the TiN and TiAgN coating layers (2) can be 6 layers. The silver content of the innermost coating layer may be 0.3%, and the silver content of the outermost coating layer may be 30%. The thickness of the innermost coating layer may be 0.1um, and the thickness of the outermost coating layer may be 10um.

[0034] The preparation method of the surface antibacterial and wear-resistant stainless steel product of the present invention adopts the magnetron sputtering method. Filling the shield with nitrogen can generate TiAgN, TiN, AgN, and Ag.

[0035] In this embodiment, 6 pieces of metallic silver with different areas are mounted on 6 pieces of titanium targets, 6 pieces of titanium targets are placed in the sputtering furnace cavity, and 6 pieces of palladium material are sputtered respectively for the 6 coating layer...

Abstract

The invention provides a surface bactericidal and wear resistant stainless steel product and its making method. The stainless steel product comprises base material(1) and some TiAgN coating layers(2), and the TiN and TiAgN coating layers(2) are coated on the outer side of the base materials(1). The content of Ag is low and the content of Ti is high in inner coating layer and the content of Ag is high and the content of Ti is low in outer coating layer. In the invention, the stainless steel preparing method employs magnetron sputtering method, target material can employ the spliced target and target, wherein the spliced target is composed of TiAg alloy, Ti, and Ag, and the target is composed of Ti and Ag, the stainless steel base material (1) and target material are placed in shield cover, and nitrogen gas is filled in the process of sputtering.

Description

1. Technical field: [0001] The invention relates to a surface antibacterial and wear-resistant stainless steel product and a preparation method thereof, and belongs to the innovative technology of the stainless steel product and the preparation method thereof. 2. Background technology: [0002] The existing surface antibacterial stainless steel products are mainly used for tableware, medical equipment, buttons, handles, door handles and many other products. At present, some foreign units have developed silver-doped stainless steel and its products, which have good antibacterial effect. The number of microorganisms is significantly reduced after 1 hour, and 99% of bacterial growth can be inhibited within 24 hours. Nippon Steel Pipe Co., Ltd. has developed antibacterial pre-coated steel sheets by using inorganic antibacterial agents, that is, the steel sheets that have been plated before galvanizing are sprayed with organic resin coatings such as polyester resins and polyoxyet...
