Abstract
The invention relates to a method for producing a metal base material that is provided with a sliding layer that has a thickness of more then 50 μm, said base material being used as a sliding element. According to the invention, the base material is coated with a paste of the sliding layer material that contains at least one high-temperature polymer in addition to a fluoropolymer, and the base material so coated is subjected to a thermal treatment. The past applied to the base material contains as the fluoropolymer between 40% by volume and 75% by volume polytetrafluorethylene (PTFE) or polytetrafluorethylene (PTFE) with other fluoropolymers added and between 60% by volume and 25% by volume of the at least one high-temperature polymer, each based on the entire composition of the finished sliding layer. The high-temperature polymer used is selected from those high-temperature polymers whose melting pint is not below 327° C., if they are mainly crystalline, or whose glass transition temperature is not below 327° C., if they are mainly amorphous.
