Novel strategies for assessing the pitting corrosion resistance of stainless steel surfaces

摘要: Pitting corrosion is one of the most common mechanisms surface damage on stainless steels. Electrochemical methods have been preferentially applied for evaluation pitting resistance steels in laboratory. Nevertheless, some them are not reliable enough and general application electrochemical field becomes difficult because required deep understanding corrosive phenomena measurement technology. Therefore, new approaches susceptibility steel surfaces laboratory as well necessary. In present paper two novel strategies including noise measurements under anodic polarization testing, an indicator test to assess introduced. Experimental results concerning influence treatments confirmed that final condition has a significant effect their future susceptibility. addition, was observed being specifically dependent achieved topography cases independent roughness parameters surface.
