CORROSION AND ITS CONTROL CORROSION * corrosion can be defined as the degradation of a material due to a reaction with its environment. * Degradation implies deterioration of physical properties of the material. This can be a weakening of the material due to a loss of cross-sectional area‚ it can be the shattering of a metal due to hydrogen embrittlement‚ or it can be the cracking of a polymer due to sunlight exposure. * Materials can be metals‚ polymers (plastics‚ rubbers‚ etc.)‚

Kulkarni Types of Corrosion and Their Effects on Aircraft Structural Integrity Introduction Today the vast majority of aircraft are made out of various types of metal. All metals are susceptible to corrosion which is why from the moment that any metallic aircraft component is manufactured it is treated to prevent corrosion. Certain elements are often added to base metals by manufacturers in order to create corrosion resistant alloys and metallic components are normally coated with corrosion resistant chemicals

CORROSION OF CEMENT PASTE In general terms cement products have good durability‚ but their strength will decrease or even damage structures with the role of some erosive media (such as soft water‚ acid water)‚ known as the erosion of cement paste. The main reasons for corrosion are: Soft-water Corrosion (Dissolution Corrosion) Rain‚ snow‚ distilled water‚ industrial condensate water‚ and the river water and lake water with low bicarbonate content‚ all of them belong to soft water.
