Corrosion is a chemical reaction that takes place in metal materials. It is a result of chemical reactions between oxygen and moisture. What results are structural degradation, which means that the metal materials will eventually weaken and become malleable. Natural corrosion is a serious safety hazard that negatively impacts companies and the public. For example, corrosive metals may contain toxic metals and harm health and the environment. However, induced corrosion is a unique industrial process that takes advantage of the beneficial aspects of corrosion.
Corrosion results from a variety of environmental contaminates. Specifically,microbiological corrosion takes place when bacteria colonies develop on a metal’s surface. This biofilm itself doesn’t cause damage, but the secreted waste products result in chemicals like methanol or sodium hydroxide. This is scientifically referred to as the act of induced corrosion. Chemically-induced corrosion creates safety and health hazards, such as leaking pipelines or metal barrels.
Most consumers aren’t aware of the fact that certain household items, such as batteries, depend on induced corrosion to function properly. For example, modern batteries contain both zinc and carbon, which are intentionally mixed because the corroded zinc will generate the electric current flow. Many other products, such as cars and motorcycles, use anti-corrosive metals. Induced corrosion is also used in consumer product research to test and prevent possible health hazards.
Stainless steel is a true wonder because it is created with chromium, which is an anti-corrosive agent. Other elements commonly used include titanium and aluminum. Titanium reinforced metals are actually used in the health care industry for implants and prosthetics. Industrial manufacturers commonly apply strong alkaloids to certain metals, such as cadmium, to induce similar effects. Keep in mind that the primary source of building infrastructure materials is metals that have been infused with both lower and higher oxygen reactive metals. In the event of corrosion, the metals with the high oxygen affinity will prevent moisture from corrupting the materials.
The construction industry relies on induced corrosion to reinforce concrete. That is, reinforced steel is an amalgamation of both concrete and steel. The two different materials must be combined together to create an even stronger structural material. Therefore, controlled corrosion is induced in concrete reinforced with steel to guarantee a permanent bond. This creation will withstand more tension and stressed inducted compression because of the minor induced corrosion.
Induced corrosion is playing an active role in helping scientists better understand metals. Researchers are currently exploring the different ways that various metals corrode in order to gain a better understanding of metal properties and possible future applications. To illustrate, the vehicle and airline manufacturing industries are experimenting with ways to increase the strength, durability and appearance of the metals they use. However, in order to accomplish this, they must clearly understand the galvanic corrosion process of metal electrolytes in order to make necessary improvements.
To review, induced corrosion offers excellent benefits, such as strong metals that prevent safety and health hazards.
