The metal coating process is rooted in the need to protect metal parts and structures from damage by environmental conditions. Metals used for structural components, mechanisms, enclosures, etc. include steel, aluminum, and iron, to name a few. These metals can oxidize or corrode when exposed to the environment and, if their working life is to be extended, a “barrier” coating must be added as protection.
Factors to consider in selecting a coating for the metal coating process:
- How much physical and environmental stress will the coating have to endure?
- Is electrical conductivity needed after coating?
- How important is the cost effectiveness of the coating to the entire application?
- Will more processes be performed after the coating you are considering?
Understanding your needs in detail will lead the way to determining the correct metal coating process.
Widely used types of coating processes for metals include:
- Electroplating
- Electroless Plating
- Painting
- Powder Coating
Electroplating forms a coating by applying electrical current to a chemical solution containing the metal part. The resulting reaction causes the coating to form on the part.
Electroless Plating uses no electrical current in forming the coating. A chemical reaction between the solution and the surface of the part forms the coating.
Painting encompasses many different forms based on endurance, color, and protection level required. Paint systems for the military can even be chemical agent resistant (CARC) for added protection for our forces.
Powder coating is available in a large selection of colors and offers excellent corrosion protection.
