 | The corrosion resistance of austenitic stainless steels in artificial seawater containing 0.2 to 0.4 mg/L dissolved ozone was investigated. According to cyclic polarization data, UNS S30400 and S31600 stainless steels are resistant to pit initiation after 8 weeks exposure to ozonated artificial seawater. However, if crevices exist, crevice corrosion is more severe in ozonated vs. aerated artificial seawater. Maximum crevice corrosion penetration rates of 8 and 5 mm/y were recorded ... |

 | Initial testing of metal alloys in ozonated vs. aerated artificial seawater has been completed for exposure times of up to 16 weeks. Five alloy groups were tested: nickel-based, stainless steel-based, titanium-based, aluminum-based, and copper-based. Three types of samples were used to evaluate corrosion behavior: weight loss, creviced and wire (electrochemical). Of the five alloy groups, titanium was the most resistant, showing little difference in the corrosion behavior between aerated and ... |

| Ozonation of sea water for biofouling control is being utilized in desalination processes, heat exchange systems, as well as in salt water aquariums. The chemistry of ozone in sea water is much more complex than in fresh water due to the high concentration of easily oxidizable, ozone-demanding species and the formation of secondary oxidants. The major secondary oxidant is bromine in the form of hypobromite and hypobromous acid (BrO(-)/HOBr) which ... |

|
| 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) ... |

|
| The effect of flow rates on the corrosion behavior of 304 stainless steel in a solution of 0.5 N NaCl containing O, 0.02, and 1.2 mg/l dissolved ozone was studied at room temperature. Flow rates ranging from 0.3 to 2.0 m/s were simulated by the use of a rotating cylinder electrode (RCE). Corrosion potentials and passive current densities were measured, and values of breakdown and repassivation potentials were derived from ... |

| The effect of flow on 304 stainless steel in a solution of 0.5 Normal NaCl containing 0, 0.02, and 1.2 mg/liter dissolved ozone was studied at room temperature. Flow rates ranging from 0.3 to 2.0 m/s were simulated by the use of a rotating cylinder electrode. Corrosion potentials and net current densities were measured and values of breakdown and repassivation potentials were derived from cyclic polarization curves. It was found ... |

|
| MOVIE-NUC is a general-purpose computer graphics display system for two-and three-dimensional models. The results of both static and dynamic analyses may be viewed as line drawings, continuous-tone color images or as an animated movie sequence. MOVIE-NUC uses the Watkins' Visible Surface Algorithm to produce realistic perspective views of the model with the hidden lines and surfaces removed. The system is written in FORTRAN and is run on the Naval Undersea ... |
