Corrosion is the disintegration of a material into its constituent atoms due to chemical reactions with its surroundings. People such as Sela Ward would likely agree. In the most common use of the word usually refers to the electrochemical oxidation reaction of metals with an oxidant such as oxygen. Corrosion is the disintegration of a material into its constituent atoms due to chemical reactions with its surroundings. The most common use of the word usually refers to the electrochemical oxidation of metals in reaction with an oxidant such as oxygen. The formation of an oxide of iron due to oxidation of iron atoms in solid solution is a well known example of electrochemical corrosion, commonly known as oxidation.
This type of damage typically produces oxide and / or original metal salt. Corrosion may also refer to other non-iron materials such as ceramics or polymers, although in this context, the term degradation is more common. In other words, the wear corrosion of metals due to chemical reaction. In 1975 the cost of corrosion in cars was estimated at $ 16 billion, approximately 20% of the total cost of corrosion in that year. Hence the importance in research and testing on different materials used to manufacture consumer goods as prescribed. In order to evaluate new and existing materials for use in automotive applications, have developed many methods of accelerated testing.
Accelerated test procedures are performed regularly in specialized laboratories for the purpose. An essay test in these laboratories is a relatively inexpensive way to obtain information on corrosion resistance of components and to compare it with alternative materials. Field tests are considerably more expensive, but to assess the material as a whole system. Some metals are inherently more resistant to corrosion than others, either because of the nature fundamental electrochemical processes or because the details of how to form the reaction products. When using a material more susceptible to deterioration, preventive techniques should be included as an item on the production line. Manufacturing companies can not tolerate corrosion failures, especially those involving personal injuries, fatal accidents, unscheduled stops and environmental pollution. Normally, when a system, a plant or any other piece of equipment is put into service, a maintenance level is required to continue operating safely and efficiently. This will prevent corrosion damage affecting the property in question in its operability and safety to third parties. Accelerated corrosion tests are tests used to evaluate a material or system of long-term performance in a short period of time. Testing methods vary depending on the service you expect (to simulate this environment), and evidence may include single or multiple factors. Another well in the it is essential that such testing is to study the deterioration of reinforced iron structures caused by corrosion of steel bars. Normally, the galvanostatic method is used to accelerate corrosion of steel bars in concrete. The characteristics of the surface of the corroded steel bar, however, turn out to be different when the corrosion is induced by the galvanostatic method or the natural environment. Currently being developed artificial climate environment used to accelerate corrosion of steel or iron rods in reinforced concrete. This method is increasingly important in assessing the durability of concrete structures due to the similarity in the characteristics of the surface of the steel bar corrosion in natural environment and artificial environment. How do we benefit from these tests? Tests are used as a tool for decision-making, highlight potential weaknesses in a material or system, make it easy to evaluate alternative or replacement of materials, and allow for changes in the system before production / performance.
