Corrosion behavior of carbon steel in 0.1M HNO<inf>3</inf> has been studied as a function of various concentrations of aqueous nanomagnetic fluid. The novel nanomagnetic fluid has been specially synthesized to achieve the stability in acidic media when it is mixed with HNO<inf>3</inf> This nanomagnetic fluid has been evaluated by gravimetric and polarization measurement techniques. It was observed that the inhibition efficiency increases with the increase in the nanomagnetic fluid concentration and reaches the maximum at the optimum concentration. This is further confirmed by the decrease in the corrosion rate. It is found that the system follows Temkin adsorption isotherm. ©2011 by NACE International.falseAcid corrosion | Nanomagnetic fluid | PolarizationConference Paper20113cpBook Series
