ABSTRACT:
For an evaluation of the peel strength of a plastic sliding layer of a laminate for sliding surface bearings, which laminate comprises a steel backing, a porous sintered bronze layer on said steel backing, and a mixture of polytetrafluoroethylene which fills the pores of the bronze layer and constitutes a sliding layer on the bronze layer, the surface of the sliding layer of a sample that has been blanked from the laminate for sliding surface bearings is activated and adhesively joined to the end face of a testing bar of a testing apparatus in accordance with ISO Standard 4624. The ultimate tensile stress is then determined.
