注入离子在基体中处于置换或间隙位置，与基体原子结合成改性层，改性层与基

The implanted ions are in a displacement or gap position in the matrix, and combine with the matrix atoms to form a modified layer. There is no clear interface between the modified layer and the matrix, so there is no risk of shedding. The use of ion implantation technology to inject Ag + or Cu2 + into the substrate surface for antibacterial modification is currently an active research area. Zhan Weiting and others used Ag / Zn antibacterial metal ion implantation on the surface of stainless steel to prepare antibacterial stainless steel. Antibacterial experiments have shown that Ag / Zn dual ion implantation can greatly improve the anti-infection of these materials against bacteria, and the antibacterial rate of Gram-negative and positive bacteria is> 99% and has broad antibacterial properties.

Injection ions are in the displacement or gap position in the substrate, and the substrate atom is bound into a modified layer, there is no clear interface between the modified layer and the substrate, so there is no risk of shedding. The use of ion injection technology to inject Ag or Cu2 into the substrate surface for antibacterial modification is an active research field. Zhan Yan and other use Ag/Zn double antimicrobial metal ion injection stainless steel surface to prepare antibacterial stainless steel. Antibacterial experiments have shown that Ag/Zn dual ion injection can greatly improve the anti-infection of bacteria in this material, and the antibacterial rate of gram negative and positive two types of bacteria has a wide antibacterial properties.

The implanted ion is in the position of displacement or gap in the matrix, and combines with the matrix atom to form the modified layer. There is no clear interface between the modified layer and the matrix, so there is no risk of falling off. It is an active research field to inject Ag + or Cu2 + into the surface of substrate by ion implantation technology. Zhan Weiting and others prepared antibacterial stainless steel by Ag / Zn dual antibacterial metal ion implantation. The antibacterial experiment showed that Ag / Zn dual ion implantation can greatly improve the anti infection of this kind of material to bacteria, and it has a wide range of antibacterial properties to gram-negative and positive bacteria whose antibacterial rate is more than 99%.<br>
