foszfátolás
Foszfátolás, also known as phosphating, is a metal surface treatment process used to improve corrosion resistance and prepare metal surfaces for painting or coating. It involves immersing the metal part in a phosphoric acid solution containing metal phosphates. The acid reacts with the metal surface, creating a thin, crystalline layer of insoluble metal phosphates. This layer is typically iron phosphate, zinc phosphate, or manganese phosphate, depending on the specific process and desired properties.
The phosphating process begins with cleaning the metal surface to remove any grease, oil, or rust. This
The primary benefits of foszfátolás include enhanced adhesion for subsequent coatings like paint, powder coating, or
