We studied atmospheric corrosion on Rapa Nui Island, using galvanized and non-galvanized SAE 1020 steel samples exposed racks. also added Charpy of both materials to directly determine the effect rate these materials' impact toughness. The results indicated a correlation between toughness loss in materials. In study, we could demonstrate from increased insular population growth contaminants whi...
