Corrosion behavior of carbon steel and galvanized steel samples was investigated using two different protection mechanisms: vapor corrosion inhibitor (10% VCI) and constant flow of dry air (RH% <40%) system. The objective of this project was to demonstrate which technique provides more protection in corrosive environments.Corrosion behaviors of carbon steel and galvanized steel samples were studied in two different conditions; the first environment contained 200 ppm chloride solution + 10% vapor phase corrosion inhibitor (VCI) addition the second test environment included 200 ppm chloride solution (injected into environment every 48 hours) with a constant flow of dry air with less than 40%RH at 20 psi applied pressure. The corrosion rate of the exposed samples were monitored for more than six months (~4300 hours) using electrical resistance (ER) probe techniques.The corrosion data have demonstrated that vapor phase corrosion inhibitors have superior advantages over the dry air system. Samples that were exposed in dry air system showed corrosion attack and red rust formation after 21 days of exposure. ER probes showed a corrosion rate of <0.08 mpy for VCI treated while the dry air samples showed a 1.1-1.3 mpy corrosion rate and ER probes were heavily corroded.
