Coatings are applied to the surface of structural components to prevent corrosion from happening. Corrosion-resistant coatings improve operational efficiency. These coatings make the parts and components much more durable as well, allowing them to last for far longer.
Types of coatings
- Zinc coatings, also known as galvanized coating, is one of the most commonly used as well as popular metal coatings around, says Thomasnet. It includes the application of metallic zinc to carbon steel. Designed to control corrosion, the process is achieved by hot-dip galvanizing, which essentially means the metal is immersed into melted zinc to get the desired coating. Zinc is a good deterrent for oxidation. But if abrasions happen, galvanic action ensures the surface is still protected. This way, coatings can keep the surface around holes as well as edges protected.
- Aluminum coatings. For these coatings, you can choose between hot-dipped aluminum silicon and hot-dipped coating of pure aluminum. Both offer excellent protection and resistance against corrosion. The first option has a heat resistance of 1250 degrees Fahrenheit, along with a heat reflectivity of 900 degrees Fahrenheit, making it ideal for applications involving heat panels, automobiles, shields and more. The second one, though, has longer lasting protection from atmospheric corrosion and is an ideal choice for a number of applications in the automotive, aerospace, medical and optoelectronic industries, to name a few.
- Electroless coatings, also known a conversion coatings, refer to coatings generated from conversion processes like the black oxide. This improves corrosion protection. It starts off with the oxidization process for metals, resulting in a blacking solution that obstructs the formation of rust. This then develops into a micro porous surface.
- Ion Plating. Thermal evaporation is used to create the coating. Processes involved in the production of this coating include electroplating and thermal evaporation along with ion and atom sputtering as well as ion implantation. If you’re looking for coatings that fit complex surfaces, this is the best kind of out there.
With quality metal coatings, you can protect your components and parts from oxidation, physical barriers and corrosion, among other things. This provides you with durable performance, allowing you to save up on costs for premature replacements, effectively cutting down on manufacturing expenses. With the right coatings, you won’t just get better longer-lasting performance, you get to enjoy cost-savings as well.
