【 摘 要 】

Surface corrosion has a major influence on ageing of high strength materials that leads to degradation in mechanical properties. Therefore,design of a component frequently implores the engineer to minimize the possibility of failure particularly by environmental deterioration. Effect of corrosive environment on high strength materials of Aluminum alloys and steels is studied. The influence of corrosion on material loss and deprivation of mechanical behaviour such as ultimate strength, yield strength and fatigue resistance arereviewed and presented.Salt spray test as per ASTM B117 and immersion in natural sea water are the usual practices followed to induce corrosion. It is evident from the literatures that corrosion has a significant effect on deterioration of mechanical behaviour of the materials.
