As explored in ScienceDirect’s article, “Atmospheric Corrosion of Carbon and Galvanized Steel Under High Rainfall Conditions,” a study analyzed the corrosion behavior of carbon and galvanized steel in high-rainfall environments, particularly in Colombia’s Chocó department. The research focused on pollutant contamination, atmospheric aggressiveness, and metal degradation over an 18-month period across three different locations: Quibdó, Andagoya, and Bahía Solano.
Findings revealed that high precipitation levels significantly accelerate corrosion by influencing time of wetness (TOW) and pollutant exposure. Carbon steel exhibited an initial formation of hematite, which later transitioned to lepidocrocite…
