Corrosion Resistance of Metal and Alloy in Artificial Urine in Presence of Sodium Chloride

R.Nagalakshmi,S.Rajendran ,J.Sathiyabama

Corrosion resistance of two metals namely mild steel (MS), Nickel Titanium super elastic alloy has been evaluated in artificial urine in the absence and presence of sodium chloride. AC impedance spectra have been used to investigate the corrosion behaviour of these metals. The order of corrosion resistance of metals in artificial urine, in the absence and also in the presence of sodium chloride was Ni-Ti super elastic alloy> mild steel.
