PPT-Introduction to Corrosion

Materials Engineering Dr Lubna Ghalib Definition Destruction or deterioration of a material due to their reaction or chemical attack by its environment Materials may be metals amp alloys or nonmetals like ceramics plastics rubber . It is intended to give an introduction to corrosion and its control in nontechnical terms More technical information is available on other areas of the NPL NCS website Bill Nimmo and Gareth Hinds NPL February 2003 brPage 2br Beginners Guide to Corro http://www.trekearth.com/gallery/Central_America/Cuba/East/Guantanamo/Baracoa/photo1001204.htm.

Metals are usually “polycrystalline” . . . an assemblage of single-crystal grains separated by grain boundaries.. Grain boundary in a polycrystalline metal (two-dimensional representation). . . CORROSION. Narrow openings, gaps, spaces, pores etc. between metal-metal components or metal-non-metal components may provoke localized corrosion.. NOTE: unintentional crevices (seams, cracks etc.) can also act in the same way. 1. Galvanic Series of Metals in Sea Water. The next slide show a table of the reactivity of metals and various alloys in sea water. Base refers to the anodic properties of the metal or alloy. Anodic refers to the giving up of electrons.. oxidization. of a metal, and the oxide flaking off.. Oxidized metal is commonly called rust. Most commonly oxygen will oxidize a metal.. Either by .

The primary aim is to identify and resolve corrosion-causing conditions to prevent failures and extend the life of the equipment. Early identification of corrosion signs and measuring the effectiveness of corrosion management are the main two objectives of corrosion monitoring. There are many techniques available to measure such data. In this article let us look at some of the best online corrosion monitoring system available. Time is a great healer, but when it comes to matters of industrial importance, it can sometimes act as an even greater destroyer. Like every human being, every machine has a life too. But with time unless you maintain it, the efficiency is going to suffer by leaps.
