Problems solved by technology

However, in actual use, both multi-arc coating and magnetron sputtering coating have defects that cannot reflect and reflect incompletely. For example, when coating black film, it is easy to cause target poisoning. The main reason is: the use of sputtering coating black In order to meet the requirements of pure black film, it is necessary to add high-concentration acetylene gas, resulting in a low concentration of argon gas, a large amount of carbon powder deposited on the surface of the target, thereby reducing the amount of sputtering; when using multi-arc plating black film, use The method of electric welding evaporates the target material, thereby generating a large amount of ion flow, which prevents the reaction gas from reaching the surface of the workpiece to be plated

Embodiment Construction

[0018] The invention is carried out in a physical vapor deposition coating furnace. The substrate to be coated is hung in the furnace. The substrate can be a metal material, a non-metal material, a fiber product, a polymer material, a dry implant material or a leather material. The antibacterial target material can be one or more of As, Sb, Se, Hg, Ag, Cu, Zn, Ce, Ca, Co, Ni, Al, Fe, S and its oxides and sulfides. The antibacterial target material The proportion in the film layer is 0.01% to 100%, and there can be other targets with special functions in the film layer, such as titanium, aluminum, zirconium, etc. with wear resistance.

[0019] In the present invention, a number of tiny pores 1 are drilled on the surface of the antibacterial target 3, and the gas tube 2 is used to pass the reaction gas into the pores 1.

[0020] The target 3 can be a planar magnetron target or a cylindrical target. The cylindrical target in the cylindrical target is the first choice when plating pre...

Abstract

This invention relates to a method for manufacturing surface anti-bacterium product by a physical gas phase deposition technology including utilizing the physical gas phase deposition technology to plate an anti-bacterium target material on a matrix surface to form a film, characterizing in drilling small air holes on said anti-bacterium target and penetrating reaction gas by windpipes, in which, said target is made of As, Se, Hg, Ag, Cu, Zn, CE, Ca, Co, Ni, Al, Fe, S and their oxides, which drills holes on the target surface to prevent the target from poisoning to realize multi-arc plating and magnetic controlled sputtering plating.

Description

Technical field [0001] The invention relates to a method for preparing surface antibacterial products, in particular to a method for manufacturing surface antibacterial products by using physical vapor deposition technology. Background technique [0002] Traditional antibacterial products are made by directly mixing antibacterial materials into metal materials, polymer materials, glaze porcelain and other substrates. This method causes a large amount of waste of antibacterial materials, and the manufacturing process is complicated and the processing cost is too high. There are some new technologies that use physical vapor deposition technology to manufacture surface antibacterial products in the prior art, such as the Chinese patent application "A surface antibacterial and wear-resistant stainless steel product and its preparation method" (application number: 200410027063.2), which provides A method for preparing wear-resistant and antibacterial stainless steel products by using ...
