Method for preparing antibacterial stainless steel by surface alloying

The invention provides a method for preparing antibacterial stainless steel by surface alloying, it's steps include: Coating auxiliary dielectric layer on stainless steel surface; An antibacterial metal layer is applied on the surface of the auxiliary medium layer; The stainless steel is heat treated to diffuse the antibacterial metal into the stainless steel; Therefore, the present invention can be applied to all kinds of stainless steel, and the antibacterial metal can be diffused and dissolved in the stainless steel, so that the stainless steel can form an antibacterial alloy layer with a certain thickness on the surface of the final molding. It can have better corrosion resistance and antibacterial ability, and has the advantage of not changing the properties of antibacterial metal or stainless steel substrate, and can control its chemical composition and antibacterial alloy layer by controlling the thickness, concentration, and heat treatment parameters of the antibacterial metal layer. Thickness, so it
