Corrosion of Metals in Tropical Environments: Part 1—Five Non-Ferrous Metals and Structural Steel^⋆ Available to Purchase

An extensive investigation has been in progress since 1940 in the Panama Canal Zone to study the corrosion rates and characteristics of fifty different metals and alloys exposed to five natural tropical environments for periods of one, two, four, eight, and sixteen years. Up to the present, specimens through the eight year period have been removed and examined. The report describes the corrosion rate of aluminum, lead, nickel, zinc, and copper along with structural steel. Corrosion data for these metals as observed in the five environments have been obtained from weight loss and pitting measurements, visual inspection and physical property studies. Corrosion rates for these metals in the tropics are related to corrosion rates previously reported for these metals in temperate latitudes. 2.2.2
