A procedure for the application of PTFE-based, self-lubricating coating on a steel bearing element whose chrome and nickel contents are less than 5%, is disclosed. The procedure is characterized by a working process whereby the element undergoes a preparatory treatment during which crystal nuclei form, followed by phosphatization treatment which forms a microcrystalline layer composed of an iron and manganese compound, then by the application of PTFE on the surface and between the crystals.
