Book excerpt: The effects of 0.02, 1.2 and 2.3 mg/L ozone on the corrosion behavior of 304 stainless steel, Monel 400, and naval brass were studied at room temperature in artificial sea water at pH 7.5, and the results were compared with those obtained for aerated solutions. Corrosion potentials and cyclic polarization curves were measured after 1 and 17 hour exposure times. Instantaneous corrosion rates were measured using linear polarization resistance (LPR) techniques. Long term (30 day) crevice corrosion experiments were also performed on stainless steel and naval brass in aerated and 0.8 mg/L ozonated solutions. Increasingly noble corrosion potentials were observed in the cases of stainless steel and Monel with increasing ozone concentration due to the noble redox potential of ozone. Naval brass, on the other hand, maintained a fairly constant corrosion potential, independent of ozone concentration, due to the formation of a bulk corrosion product on the metal surface. LPR measurements on naval brass reflected the corrosion rates of both zinc and copper due to dezincification occurring on the metal surface. These corrosion rates were found to Corrosion, Stainless steel, Copper nickel alloy, Dissolved ozone, Chloride solutions be independent of ozone concentration and exposure time, although it appears that exposure to 0.02 mg/L ozone after 17 hours resulted in complete dezincification at the surface. The corrosion rate of Monel was found to increase at elevated ozone concentrations, independent of exposure time. Stainless steel, however, showed a decreasing corrosion rate with increasing ozone concentration after one hour due to ozone quickly stabilizing the passive film.

This book was released on 1989 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemical experiments on the effect of dissolved ozone on the corrosion behavior of Copper-30 Nickel and 304 L stainless steel have been performed in 0.5 N Sodium chloride solutions at room temperature. The experiments performed included measurements of corrosion potential as a function of time and ozone concentrations, cyclic polarization experiments, iso-potential measurements of current densities and Auger electron spectroscopy studies of the chemical composition of the corrosion product films. The results of these experiments have shown that for both Cu-based alloy and the stainless steel, the corrosion potential exhibits a marked shift to more noble values (approx. 300 mv) for ozone concentrations less the 0.2 - 0.3 mg/l. At higher ozone concentrations the corrosion potential is virtually independent of the level of ozone dissolved in the solution. The presence of dissolved ozone resulted in a reduction in the corrosion rate for the Cu-30 Ni alloy, as measured by a significant decrease in the current density at a constant applied potential. This improvement in the corrosion resistance appears to be related to a reduction in the corrosion product film thickness and a higher fraction of oxygen to chloride in the corrosion product film. For the stainless steel, Auger electron spectroscopy indicated no appreciable differences between the passive film produced in ozonated solutions versus those in unozonated solutions.
