Sažetak
In this Paper potentiodynamic and Tafel (anodic and cathodic) polarization tests were conducted in order to relate the dependence of surface roughness on the resistance to pitting corrosion (pitting potential) of AISI 316 stainless steel in spring water at 20°C. Furthermore, uniform corrosion resistance of AISI 316 steel was studied. Tests were performed on seven samples that were polished with emery paper with silicon carbide particles of various grits. Using scanning electron microscope qualitative evaluation of surface roughness was done, and roughness parameter Ra was measured using stylus instrument. Achieved results show that with decreasing mean arithmetic deviation of profile investigated surface significantly increases the resistance to pitting potential, and expands the passivation area of the AISI 316 stainless steel in spring water.
