Problems solved by technology

[0004] Our research found that the coating formed by the invention is composed of Ti-Cu-N, Zr-Cu-N, Ti-Ag-N, Zr-Ag-N, Ti-Cu-Sn-N, Zr-Cu-Sn-N , Ti-Sn-N or Zr-Sn-N film, although it has excellent antibacterial ability, it is still not ideal in terms of corrosion resistance and wear resistance.
The reason is that the soft Cu, Sn, Ag in the film is mixed with the hard Ti, Zr, and the presence of soft materials such as Cu, Sn, Ag will be detrimental to the wear resistance and corrosion resistance of stainless steel products. Moreover, the film has a single-layer structure, and under the joint influence of the material change of the stainless steel product itself and external mechanical and chemical factors, the film is easily damaged, which will also have an adverse effect on the wear resistance and corrosion resistance of the stainless steel product
Moreover, in order to take into account the wear resistance and corrosion resistance of this invention, the improvement of Cu, Sn, Ag content in its film is restricted, and correspondingly, the improvement of antibacterial performance is also restricted

Embodiment 1

[0037] In this embodiment, the metal product with the metal antibacterial composite film on the surface includes a metal product substrate, the surface of the metal product substrate is covered with an inner metal nitride film layer, and the inner metal nitride film layer is covered with an intermediate metal nitride film layer, the middle metal nitride film layer is coated with an outer metal nitride film layer. In this embodiment, the material of the metal product substrate is stainless steel; the inner metal nitride film layer is a Cr-N film layer; the middle metal nitride film layer is an Ag-N film layer; the outer metal nitride film layer is a Ti-N film layer layer. The inner metal nitride film layer, the middle metal nitride film layer and the outer metal nitride film layer are combined together to form a metal antibacterial composite film.

[0038] The basic steps of the manufacturing method of the above-mentioned metal product with metal antibacterial composite film o...

Embodiment 2

[0067] The material of the metal product substrate in this embodiment is the same as that of Embodiment 1, and the equipment and process steps adopted are also the same as Embodiment 1.

[0068] The difference between the metal product of this embodiment and Embodiment 1 is that in the metal antibacterial composite film, the inner metal nitride film layer is a Ti-N film layer, the middle metal nitride film layer is a Sn-Cu-N film layer, and the outer nitrogen film layer is a Ti-N film layer. The metallization film layer is a Cr-N film layer.

[0069] The manufacturing method of this embodiment differs from that of Embodiment 1 in that: the material of the inner layer metal target is titanium, the material of the middle layer metal target is a combination of tin and copper (where tin is 25%wt, copper is 75%wt), and the outer The material of the first-layer metal target is chromium; in step (2), argon gas is introduced to clean the metal product substrate 9 for 15 minutes; in st...

Embodiment 3

[0082] The material of the metal product substrate in this embodiment is the same as that of Embodiment 1, and the equipment and process steps adopted are also the same as Embodiment 1.

[0083] The difference between the metal product of this embodiment and Example 1 is that in the metal antibacterial composite film, the inner metal nitride film layer is a Ti-N film layer; the middle metal nitride film layer is a Sn-Cu-N film layer; the outer nitrogen film layer is a Ti-N film layer; The metallization film layer is a Zr-N film layer.

[0084] The manufacturing method of this embodiment differs from that of Embodiment 1 in that: the material of the inner layer metal target is titanium, the material of the middle layer metal target is a combination of tin and copper (where tin is 30%wt, copper is 70%wt), and the outer The material of the layered metal target is zirconium; in step (2), pass argon gas to clean the metal product substrate 9 for 30 minutes; in step (3), the time fo...

Abstract

A metal product with a metal antibacterial composite film on the surface comprises a metal product base body and is characterized in that the surface of the metal product base body is coated with an inner nitrided metal film layer, the inner nitrided metal film layer is coated with a middle nitrided metal film layer, and the middle nitrided metal film layer is coated with an outer nitrided metal film layer; the metal material contained in the inner nitride metal film layer is one or a combination of more of chromium, titanium, zirconium, silver, copper and tin; a metal material contained in the middle nitride metal film layer is one or a combination of more of silver, copper, tin, chromium, titanium and zirconium; and the metal material contained in the outer nitride metal film layer is one or a combination of more of chromium, titanium and zirconium. The invention further provides a manufacturing method of the metal product with the metal antibacterial composite film on the surface. The metal antibacterial composite film is arranged on the surface of the metal product, and the metal product has excellent antibacterial performance, wear resistance and corrosion resistance through the metal antibacterial composite film.

Description

technical field [0001] The invention relates to the technical field of plating materials with metal materials, in particular to a metal product with a metal antibacterial composite film on the surface and a manufacturing method thereof. Background technique [0002] At present, there are stainless steel products (such as stainless steel tableware) coated with copper-tin alloy film on the surface, and the antibacterial ability of this product has been proved. Metal tin (Sn) has a good effect of sterilization, purification and preservation. Generally speaking, the larger the proportion of tin in the copper-tin alloy film, the stronger the antibacterial ability. However, the characteristics of tin are relatively soft. As the proportion of tin increases, the wear resistance of the copper-tin alloy film will also decrease. Therefore, the requirements for the use and washing of this type of stainless steel products are very high, which is not conducive to popularization and applic...
