Methodology Investigation. Comparative Corrosion Evaluation; Fort Sherman, Panama, and Kure Beach, North Carolina
Abstract
The US Army Tropic Test Center initiated a project in early 1986 to furnish quantitative data relating the severities of atmospheric corrosion of steel and iron at Tropic Test Center exposure sites to those of the well-known sites at Kure Beach, North Carolina. All samples were analyzed at the LaQue Center laboratories to ensure uniform treatment of samples and identical analytical methods. Samples of mild steel and ingot iron were exposed for durations of three and twelve months on a quarterly basis for a total of four 3- month and five 12-month exposures at four sites in or near Fort Sherman, Panama and two sites at Kure Beach, North Carolina. Results indicate that the Fort Sherman Breakwater and Coastal Sites are substantially more aggressive toward steel and iron than either of the Kure Beach Sites, and that the Fort Sherman Open and Forest are somewhat less aggressive than either Kure Beach Site. Relative severities varied from season to season, but for an average of all seasons, 12-month exposure of mild steel shows the Breakwater to be about 10 times as aggressive as the Kure Beach 25-meter lot, and the Coastal Site to be 5 times as aggressive as the 25-meter lot.
