Metal is one of the best discoveries man has ever come up with. It’s sturdy and flexible. It has many applications. The problem is, it’s not completely invincible. It’s susceptible to the damages brought about by the forces of nature.
Regardless of the type of solid metal, corrosion is one of the longstanding problems people have to face. It’s present everywhere. Homeowners dread the occurrence of rust in their roof, while car owners feel anxious when traces of red and brown markings start to appear on the surface. In industries that depend on metallic structures, it causes expensive problems. This is why many invest in stress corrosion cracking assessments from companies like MearsCorrosion.com.
General Definition of Rusting
Foremost, rusting or corrosion is a chemical reaction. A chemical reaction occurs when one or more different substances interact with each other and produce something else. Chemical changes happen, meaning one cannot reverse the process.
How it Happens
Corrosion happens in the presence of moisture. It’s a chemical reaction with oxygen in the presence of moisture on a metal’s surface. Iron oxide or rust forms when this interaction occurs. To be more specific, water combines with carbon dioxide forms a basic type of acid, which in turn is detrimental to the composition of the metal. Corrosion gets faster when metals are exposed to elements, such as seawater and acid rain.
The first thing to do to prevent corrosion is to keep moisture away. This is possible through using paint. Alloying, or combining two metals, also works. For long-term options, many go for galvanizing. Through this process, metals are dipped in molten zinc.
These are only some of the things you need to know about rusting. It may be part of natural processes, but there always will be measures to prevent it from causing significant damage.
