What is coating in metal production?
Metallic coatings contain a metallic element or alloy. Metallic coatings can be applied by using a sprayer, electrochemically, chemically or mechanically. These coatings are applied on equipment requiring a shiny or glossy appearance and protection from sunlight, corrosion and oxidation.
How are metal coatings applied?
There are four commonly used methods of applying metal coating to steel surfaces. These are hot-dip galvanizing, thermal spraying, electroplating and sherardizing. The latter two processes are not used for structural steelwork but are used for fittings, fasteners and other small items.
What is the most durable coating for metal?
Epoxy Steel Coatings: Epoxy coatings are one of the most widely used steel coatings in industrial and marine markets. Epoxies are known for having excellent adhesion to steel and provide good chemical resistance.
Where are metal coatings used?
Some types of metal coatings are designed to protect the metal from rust, corrosion, dirt and debris. This is important for applications in outdoor equipment, like boats, heavy equipment, automobiles, trains, and airplanes.
What are the types of metallic coating?
Metal Coatings
- Anodizing.
- Galvanizing.
- Electroplating.
- Powder Coatings.
- Porcelain Enamel Coatings.
What are the types of metal coating?
Galvanizing. Galvanizing involves immersing the metal (mostly steel or iron) in a molten zinc bath. Once removed, the coated metal reacts with oxygen and carbon dioxide in the atmosphere to form a protective zinc carbonate layer.
What are industrial coatings?
Industrial coatings are essentially a type of paint that is applied on various derivatives like concrete or steel. It’s caked on in a way that is designed to be both aesthetic as well as protective. There are many different kinds of industrial coatings.
What are the common coating materials?
Typical coating materials are:
- Pure metals, such as Aluminum (Al), Copper (Cu), Molybdenum (Mo), etc.
- Alloys, such as Nickel Chrome (NiCr), Nickel Aluminum (NiAl), Aluminum Bronze (CuAl), etc.
- Ceramic (Oxide), such as Aluminum Oxide (Al2O3), Chrome Oxide (Cr2O3), Zirconium Oxide (ZrO2), Titanium Oxide (TiO2), etc.
