MATERIALS IN ENGINEERING PROJECTS: ENVIRONMENTAL DEGRADATION
Summary - All materials are prone to environmental degradation. Degradation happens due to chemical factors, electrochemistry, radiation or wear. The atmospheric attack happens with direct oxidation by chemical reaction between metal and atmospheric oxygen and sometimes nitrogen and sulfur. Corrosion may be defined as a process of destruction of material by the action of the environment. The phenomenon of deterioration of materials caused by the combined action of mechanical stresses in corrosive medium
