Gold is a pure substance that is very resistant to chemical reactions.
So while a metal may not rust, it can still be susceptible to corrosion. Rust is a type of corrosion exclusive to iron and iron-containing alloys, while corrosion refers to any reaction involving oxidation or other chemicals. What Is Corrosion?ĭespite common belief, corrosion and rust are not the same. As rust compromises the strength of a metal, it is important to eliminate any possibilities of rust during the construction or design phase of a project. Exposure to salt, sulphur dioxide and carbon dioxide can further accelerate this process. Water molecules can seep into small gaps within metal, quickly delivering oxygen molecules into the iron and speeding up the oxidation process. Rust is a chemical reaction that combines water and oxygen to form iron oxide, which is the flaky orange-brown substance that builds up on the surface of an iron containing compound. Often the most resistant metals are combinations of many resistant substances. Rust is a form of corrosion that effects alloys containing iron, however, many metals have their own forms of corrosion. There are many different metals that are resistant to corrosion and rust, and combinations of these are often the best solution to fend off oxidation. Corrosion-resistant alloys are crucial in many facets of life, from industry and commercial purposes to simply washing the dishes.
