XPS Investigation of Passive Layer on Copper-Bearing Antibacterial Ferrite Stainless Steel


Article Preview

After solid-solution and aging treatment, the copper-bearing ferritic stainless steel has been investigated by TEM fitted with X-ray EDS and XPS methods. The TEM and EDS shown that the rod-like precipitation phase was є-Cu, and distributed dispersively throughout in the matrix. The most important result from XPS analysis confirmed that except the topmost of passive film, copper appeared as element state and its concentration kept constant in the inner surface of the material. It was found that the material shown an excellent antibacterial property to staphylococcus and coliform bacteria, after passive film elimination,
