Study of the antibacterial function of enamel surface with Ag element diffusion

The enamel with the excellent antibacterial function can be made by Ag element diffusion at the enamel surface. With the help of SEM and EPMA, the microstructure and Ag element concentration of the enamel surface after Ag element diffusion are studied, and the influence of Ag element diffusion on the antibacterial function of the enamel surface is investigated. The results show that Ag concentration in the enamel surface is the main contribution to the antibacterial effect, Ag element diffusion does not damage the surface structure of enamels at the certain time and temperature, and the enamel surface still has the excellent acid resistance after the Ag element diffusion.
