konversiopäällysteitä
Konversiopäällysteitä, often translated as conversion coatings or passivation treatments, are chemical treatments applied to metal surfaces to improve their corrosion resistance and paint adhesion. These coatings work by converting the surface of the metal into a non-reactive layer, typically an inorganic compound.
The most common types of conversion coatings are chromate conversion coatings, phosphate conversion coatings, and newer,
Phosphate conversion coatings, such as zinc phosphate and iron phosphate, are applied to steel, aluminum, and
More modern conversion coatings aim to reduce or eliminate hazardous materials like chromium. These technologies, often
The application process for conversion coatings typically involves cleaning the metal surface, followed by immersion in
