Paper Title:
Effect of Ag Doping in 2205 Duplex Stainless Steel on Corrosion Resistance
  Abstract

Anti-bacterial property is a major concern of material use in many areas, such as food industries, hospitals, and kitchenware. It is well known that Ag owns the ability to destroy the cell walls and cell membranes of bacteria to inhibit their breeding. Therefore, Ag implanted on the material surfaces is a popular process in biomedical application. Once the implanted layer is destroyed, the well-effective antibacterial property is also ceased. In order to improve the effectiveness of bacterial characteristics, adding Ag in 2205 duplex stainless steel can maintain the bacterial property for a long period of time than Ag-implanted process. 2205 duplex stainless steel possesses excellent corrosion resistance, high strength, and superior workability, owing to possess both austenite and ferrite phase. Among them, 2205 duplex stainless steel was adopted as the test material, doping various Ag contents in this study. The result reveals that Ag content increased with ferrite phase fraction increasing. It showed Ag is the stabilizer of ferrite. In addition, the solubility of Ag into Fe was extremely low and Ag particles were distributed randomly. However, polarization test was carried out to investigate the ability of corrosion resistance. The test result showed adding Ag in 2205 duplex stainless steel had obvious contribution to decrease its corrosion resistance.
