Corrosion (rust) is one of the problems that cost industries million of dollars each year. To prevent this kind of high cost, firms must understand this natural procedure and how to prevent it. To save cash companies never use real metals. You will discover not many metals found in their pure point out. An example of a pure steel would be rare metal. Most metals are extracted as pepite. Ores happen to be oxides. The moment pulling the oxygen from the ore, applying energy and heat, celebrate a genuine metal. For instance , if high temperature and strength are applied to an flat iron ore or iron oxide it becomes iron. This reaction is called lowering. Reduction is definitely when a material gains an electron. When a substance loses an electron, it is called oxidation. Every time a metal, particularly iron, has the capacity to recombine with oxygen it becomes an iron oxide or iron ore once again. When ever iron oxidizes, it corrodes in to the familiar brownish red color called rust. In other words, corrosion is an iron or metal seeking to return to it is original or natural state. Most companies employ iron to make bridges, properties, etc . The several types of iron used include: solid iron or perhaps wrought iron. Cast straightener is an iron metal that contains 2-4% carbon, and 1-3% si. Wrought straightener is virtually a natural metal, which will resist corrosion better than cast iron. I chose this test because of the sum of corroding I see everywhere. Many of the complexes that we visit are made of iron or steel. It always made me think about how the building contractors prevent corroding from occurring so that these types of buildings may fall apart. Safeguarding the revealed metal may be the answer!
