Phosphating: effective protection of metal surfaces
Phosphating is a surface treatment process that forms a phosphate on the surface of metal. Phosphates have a crystalline structure that provides good adhesion to the metal surface. Phosphating has several advantages, including:
- Increased corrosion resistance: the phosphate layer formed by phosphating protects the metal surface from corrosion.
- Improves adhesion: the phosphate layer formed by phosphating improves the adhesion of paint, varnish or other coatings to the metal surface.
- Reduces friction: A phosphate coating reduces friction, improving the performance of metal parts.
- Provides a more aesthetically pleasing surface: the phosphate layer, created by phosphate coating, makes metal parts more aesthetically pleasing.
Phosphating is widely used for surface treatment of various metals, including:
- Steel
- Iron
- Copper
- Brass
- Bronze
Phosphating is often used in the following applications:
- Brass
- Metal parts
- Machine parts
- Fasteners
Phosphatisation is a relatively simple process consisting of the following steps:
- The workpieces are cleaned of dirt and grease.
- The workpieces are placed in a chemical solution containing phosphates.
- The workpieces are kept in the chemical solution for a specified period of time.
- The workpieces are removed from the chemical solution and rinsed with water.
If you manufacture or use metal parts, phosphating is an excellent way to protect surfaces effectively. Our qualified staff will be happy to help you select and implement a phosphating process.
The benefits of phosphating
Phosphating has many advantages, the most important of which are:
- Increased corrosion resistance. This is particularly important for metal parts that are used outdoors or in wet environments.
- Improves adhesion: a phosphate layer formed by phosphating improves the adhesion of paint, varnish or other coatings to the metal surface. This is important to ensure that coatings adhere permanently to the metal.
- Reduces friction: Phosphate coating reduces friction, thus improving the performance of metal parts. This is particularly important for metal parts that slide or rub against each other.
- Provides a more aesthetically pleasing surface: the phosphate layer formed by phosphate coating makes metal parts more aesthetically pleasing. This is particularly important for metal parts that are used in visible areas.
