    Corrosion and Rusting Introduction Some people may be annoyed by their car ?wearing out?. Kids may have trouble with rust forming on their bicycles. One may think how to prevent rusting, but do one knows what is happening when a metal corrode? ?Corrosion is defined as the involuntary destruction of substances such as metals and mineral building material by surrounding media, which are usually liquid (i.e. corrosive agents).? Most metals corrode. During corrosion, they change into metallic ions. In some cases, the product of corrosion itself forms a

    Aircraft Materials “CentrAl” Corrosion and fatigue have both been a major concern for aircraft maintenance for many years because of aging aircraft. This paper will discuss the importance of corrosion and fatigue and a brief description of what exactly the two are. Once they have been discussed, it will lead the paper into “CentrAl”, which is central reinforced aluminum. Deterioration of a material as a result of reaction with its environment, especially with oxygen is corrosion. Although the term is usually applied to metals, all materials, including ceramics, plastics, rubber, and wood

    Importance Of Water

    Water is very much precious for our life. Life as we know it can not exist without water. Seventy-five % of the Earth is covered in water providing an environment for organisms to live in. the water molecule is made up of two hydrogen atoms and one oxygen atom. As oxygen atoms are more electronegative that hydrogen atoms the electrons shared covalently between the oxygen and the hydrogen atoms tend to spend more time near the oxygen atom making it partially negative and making the hydrogen atoms partially positive. The partial charges in the water molecule allow it to form weak or hydrogen bon
