Renewable Resources in Corrosion Resistance

摘要: Corrosion of metals or alloys occurs due to chemical electrochemical reactions with their environment, which often results in drastic deterioration the properties materials comprising thereof. takes place on a steel surface, development anodic and cathodic areas, through oxidation reduction reactions, forming oxides alloys. There are several corrosion causing agents “corrodents” such as soot, sulphate salts, chloride ions, temperature, salinity, pH, dissolved gases, humidity, bacteria, sand, gravels, stones, mechanical stresses also protection methods employed for resistance application alloys, composites, inhibitors, protection, protective linings coatings (Bierwagen, 1996; Ghali et al., 2007; Raja& Sethuraman, 2008; Sorensen al.,2009). Notwithstanding, has become gigantic problem today every nation. The colossal detrimental impact economy country can be manifested billions dollars spent annually combat control it.
