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 ?m, 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.

Abstract: Disclosed is a method for the production of support materials, wherein a web of a metal support fabric is continuously provided with a sliding layer covering the support fabric on one side and predominately containing polytetrafluorethylene (PTFE). The support fabric is coated with a paste made of the material of the sliding layer and one side of said support fabric is guided in full contact with another web of material during the coating process.

Abstract: A method for the production of bearing materials is disclosed, in which a strip of a metallic woven support is continuously provided with a slip layer mostly comprising polytetrafluoroethylene (PTFE), covering one side thereof. The woven support is coated on one side with a paste of the material for the slip layer, whereby the woven support runs with the lower surface thereof in full-surface contact with a roller during and directly after the coating.

Abstract: In accordance with the method according to the invention, for the production of the plastics overlay, first of all a paste is made of a plastics dispersion and fillers. This paste is free of organic solvents and is applied to a sintered porous metal layer. The multilayer material thus produced is then sintered. Since the use of organic solvents is dispensed with, health risks and the risk of fire are reduced. Moreover, the composite materials produced according to the invention exhibit excellent cavitation resistance. In addition to conventional lubricant-free applications, such as bearings, these composite materials may consequently be used in particular in gear pumps and shock absorbers.
