.... Corrosion rate maps and corrosivity category maps will be generated based on the corrosion rates of thirteen metals and alloys at different sites on Oahu. Atmospheric data maps including variables such as time-of-wetness, humidity, temperature and chloride deposition rate will be generated from data...

...Abstract In this study, a time-of-wetness (TOW) sensor was fabricated and evaluated according to wet/dry cycle. A thin film electric resistance (TFER) probe war also applied in the same environment for the measurement of corrosion rate. The TOW sensor could not differentiate the wet and dry time...

... at the locations tested in this study cannot be readily explained by either of these approaches. The monthly or seasonal corrosivity variations do not track well with monthly variations in time-of-wetness (TOW) or SO₂ concentration. It is possible that the approach of averaging TOW, SO₂...

... losses up to 20 mils (0.5 mm) and pits up to 100 mils (2.5 mm) deep. Electrical resistance corrosion probes, time-of-wetness sensors and thermocouples have been attached to cylinder bodies. Atmospheric conditions are monitored using rain gauges, relative humidity sensors and thermocouples. Long-term (16...

... or nickel sensors facing the sky or the ground have also been exposed. The ACRMs provide a continuous record of the time-of-wetness and atmospheric corrosion rates. The results of the field tests show that corrosion rates for galvanized steel are very low with the lowest rates being observed in the winter...

...INTRODUCTION The most important factor to consider in atmospheric corrosion is time-of-wetness. In field experiments of corrosion behavior, this parameter is usually estimated from climatic factors such as relative humidity or hours of rainfall. A metal surface will be wet when vapor pressure...
