[0040] Antibacterial Knives

[0041] like figure 2 As shown, the antibacterial knife 10 according to the first embodiment of the present disclosure may include a knife body 11, a predetermined depth from the surface of the knife body 11 to the inside of the knife body 11 is the infiltration layer 13 infiltrated with the antibacterial agent 12, the thickness of the infiltration layer 13 In the penetration layer 13, the area occupied by the antibacterial agent 12 per unit area is 2‰~2% of the unit area.

[0042] According to an embodiment of the present disclosure, the cutter body 11 may be martensitic stainless steel. As an example, the martensitic stainless steel can be, for example, 2Cr13, 3Cr13, 4Cr13, and 5Cr15, etc., and preferably can be 3Cr13 and 5Cr15. However, it should be understood that the material of the cutter body 11 of the embodiment of the present disclosure is not limited by the above materials. According to an embodiment of the present disclosure, the a...

Abstract

The invention provides an antibacterial cutter and a manufacturing method of the antibacterial cutter. The antibacterial cutting tool comprises a cutting tool body, the cutting tool body comprises titanium alloy, titanium in the titanium alloy is oxidized in situ on the surface of the cutting tool body to form titanium dioxide, a titanium dioxide layer is formed on the surface of the cutting tool body, and in the titanium dioxide layer, the titanium dioxide in the titanium dioxide layer is larger than the titanium dioxide in diameter. And the weight of the titanium dioxide is greater than or equal to 95% of the weight of the titanium dioxide layer. According to the antibacterial cutter disclosed by the invention, the titanium dioxide layer is formed on the surface of the titanium alloy serving as the material of the cutter main body through in-situ oxidation, so that the binding force between the titanium dioxide layer and the cutter main body can be improved, and the titanium dioxide layer is prevented from falling off. In addition, the titanium dioxide layer is only formed on the surface of the cutter main body, so that the hardness of the titanium alloy cutter main body is not influenced, and the titanium dioxide layer has the advantages of wear resistance and the like.

Description

technical field [0001] The present disclosure relates to the field of knives, in particular to an antibacterial knife and a manufacturing method of the antibacterial knife. Background technique [0002] Knives are indispensable tools in people's lives, such as kitchen knives, table knives, fruit knives, etc. Because knives are exposed to media such as water or organic matter for a long time in daily life, knives are easily corroded and bacteria breed, which affects people's health. [0003] In the prior art, antibacterial knives are mainly manufactured by the following two methods. [0004] The first method is to spray a layer of antibacterial coating on the surface of the existing martensitic steel and then sinter at high temperature to form the antibacterial coating. However, the coating formed by this method has low hardness and is prone to problems such as scratches or even peeling of the coating after a period of use. In addition, the formation of an antibacterial co...
