1. Coating: Coatings are a material applied to the surface of an object and act as a barrier that prevents corrosion from reaching the substrate. Coatings can be applied to a variety of substrates, including those made of metal and reinforced concrete. Coatings can protect these metals and materials from the surrounding environments by the exclusion of moisture and oxygen against rust or by forming a sacrificial oxide layer similar to galvanic corrosion.
There are various terms that can be used to describe effective rust and corrosion protection, they include high-performance coatings (HPCs), anti-corrosion coatings, and protective coatings. Whatever you call them, these coatings are designed for specific applications and engineered to withstand very harsh environments and extreme weather conditions like windblown sand or rain as well as equipment vibrations and salt spray intrusion. They serve the following purposes
Resistance to chemicals
Resistance to abrasion
Resistance to impact
Ability to retain color and gloss
Temperature resistance; high temperature (up to 500°F) and low temperature (up to -60°F)
2. Cathodic Protection: This is accomplished through electrochemical means. To prevent corrosion, active sites on the metal surface are converted to passive sites by supplying electrons from another source, typically galvanic anodes attached to or near the surface. Aluminum, magnesium, and zinc are some metals used in anodes.
3. Hot-dip galvanization: This method of corrosion prevention entails immersing steel in molten zinc. The iron in the steel reacts with the zinc to form a tightly bonded alloy coating that protects the steel. They are used to protect things like artistic sculptures and playground facilities from corrosion. Unfortunately, galvanization cannot be performed on-site, so companies must remove equipment from service to be treated.
4. Corrosion Inhibitors: These are chemicals that cause a reaction on the metal’s surface or in the environment, halting the chemical action that leads to corrosion.
Rust and Corrosion protection can be done in several ways, but coatings are one of the most common. Corrosion is a serious problem that threatens the integrity of structures and equipment. Corrosion is the gradual deterioration of a material, usually a metal, as a result of chemical reactions with its surroundings. Corrosion can significantly reduce the life of metal or, in extreme cases, cause complete failure. Corrosion can have serious economic effects because it causes products to fail prematurely.
