Investigation of Initial Atmospheric Corrosion of Carbon and Weathering Steels Exposed to Urban Atmospheres in Myanmar

Figure 6

The morphology of corrosion products: (a) after one month: plate (A) and globular (B) lepidocrocite; (b) after two months: bar type lepidocrocite; (c) after four months: akaganeite; (d) after five months: magnetite. The morphology of corrosion products: (e) after six months: sandy crystals (C) and bar-shaped (D) lepidocrocite; (f) after seven months: sandy crystals lepidocrocite; (g) after eight months: sandy crystals (E) and flowery (F) lepidocrocite; (h) after nine months: globular (G) and needle-shaped goethite on the surface of globular (H) lepidocrocite; (i) after twelve months: worm net lepidocrocite (I) and cotton ball goethite (J).
