Long-Term Corrosion Behavior of Materials in the Marine Atmosphere

Abstract

The relative corrosion resistance for numerous materials of interest to architects and engineers as well as the marine construction and automotive industries are presented. Results of exposures in the natural marine atmosphere at Kure Beach, NC, for up to 45 years are included for steels, stainless steels, aluminum alloys, copper, nickel, and titanium alloys.

Survey of degradation modes of four nickel-chromium-molybdenum alloys

“…lutions is also dependent c_ the cation species present Table 29 shows a group of nickel-base alloys that (Farmer et al 1988). A recx at study suggests that magexhibit long-term resistance to marine atmospheric cornesium ions are very aggressive species in seawater rosion (_<1l.trn/yr) (Baker 1988). Included among these even though they represent only a fraction of the total alloys are Alloys 825,600, 625, 400, and C. Corrosion dissolved solids (Shold and Ohlaka 1989).…”

“…Alloys C and 625 usually have better corrosion resistance than Alloys 600 Long-term atmospheric corrosion and stress cormand 400 in seawater (see Table 27). sion tests of numerous materials have been performed at Stress corrosion testing of various materials was Kure Beach, N.C. (Baker 1988). The tests were coninitiated in 1961.…”

Thermodynamics of corrosion and potentiometric methods for measuring localized corrosion

“…The long-term stability of the passive fi lm is still not completely understood (Baker, 1986). If the passive fi lm becomes unstable, the metal surface will corrode at the higher rate.…”

Atmospheric Corrosion Resistance of Skyward- and Groundward-Exposed Surfaces of Zinc- and 55% Al-Zn Alloy-Coated Steel Sheet

“…The two marine sites were located at Kure Beach, North Carolina and have been described in detail previously. 3 The rural site was at Saylorsburg, Pennsylvania in the Pocono Mountains roughly 50 km (30 miles) north of Bethlehem, Pennsylvania. The industrial site was located on South Mountain in Bethlehem in sight of coke ovens that are operated within a few kilometers.…”
