    Corrosion is the gradual destruction of materials (usually metals) by chemical reaction with its environment. In the most common use of the word‚ this means electrochemical oxidation of metals in reaction with an oxidant such as oxygen. Rusting‚ the formation of iron oxides‚ is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal. Corrosion can also occur in materials other than metals‚ such as ceramics or polymers‚ although

    TREATMENT OF CORROSION Regardless of the type of corrosion or the metal involved‚ corrosion treatment requires three basic steps: 1. Remove as much of the corrosion as possible. 2. Neutralize any residual material. 3. Restore the protective surface film. CORROSION REMOVAL As previously discussed‚ the first step in corrosion control must be cleaning the surface. After the surface is completely clean and it is determined that corrosion does exist‚ the damage must be carefully assessed

    Types of Corrosion 1. Discuss the major types of corrosion. Uniform Corrosion: Uniform corrosion is characterized by corrosive attack proceeding evenly over the entire surface area‚ or a large fraction of the total area. General thinning takes place until failure. On the basis of tonnage wasted‚ this is the most important form of corrosion. (corrosion-doctors.org) This reminds me of some of the contractor spec’s I have seen for just this type of corrosion. Many of the clarification mechanisms

    is known as corrosion of iron and its alloys such as steel or cast irons. Rust can be found on cars‚ metal pipes‚ aircrafts and anywhere with iron‚ copper and aluminium. Corrosion can be concentrated locally to form a split or crack‚ or it can extend across a wide area which causes corroding on surfaces. Because corrosion is a diffusion-controlled process‚ it occurs mainly on exposed surfaces. Besides costing millions of dollars in aircraft inspections and repair work‚ corrosion can lead to massive

    Corrosion of Metals Introduction Have you ever had a bike that went rusty‚ figure 1? If the paint is scratched and the rust allowed to spread‚ it is very difficult to repair the frame so it looks as good as new again. Rusting costs us millions of pounds each year‚ either through replacing things or through trying to prevent it happening in the first place. Figure 1: Bike rusting. In this booklet you learn about rusting and ways of stopping it‚ followed by a look at another metal‚ aluminium that
