What is phosphating?<\/h2>\n\n\n\n

Phosphating is a chemical surface conversion process in which the surface of ferrous metals, such as steel and cast iron, is transformed into a protective layer of insoluble, non-conductive phosphate crystals.<\/p>\n\n\n\n

This coating, which is tightly bonded to the crystalline lattice of the base metal, performs a dual function:<\/p>\n\n\n\n

    \n
  • Anti-corrosion barrier:<\/strong> protects the metal from oxidation and atmospheric agents.<\/li>\n\n\n\n
  • Adhesion substrate:<\/strong> its microporous structure makes it an ideal base for paints, protective oils and lubricants, improving the mechanical performance of the component.<\/li>\n<\/ul>\n<\/div>\n\n\n\n
