Abstract
The invention relates to an anti-friction coating () for a multi-layered friction bearing () made from a tin-based alloy which, in addition to tin, contains at least one element from the group comprising antimony and copper as the main alloying element, optionally lead and/or bismuth, and unavoidable impurities originating from the elements during the manufacturing process, and the proportion of antimony is at most 20% by weight, the proportion of copper is at most 10% by weight and the total proportion of lead and bismuth is at most 1.5% by weight and the total proportion of copper and antimony is between 2% by weight and 22% by weight, and tin is present in the form of inter-metallic phases and as a tin phase with beta-tin grains, and the beta-tin grains in the tin-based alloy have at least one preferred orientation, and an orientation index M{hkl} based on the formula of at least one set of network levels M{hkl} has or exceeds the value 3.0, and I{hki} stands for the X-ray diffraction intensities for the {hkl} planes of the anti-friction coating and I{hkl} stands for the X-ray diffraction intensities of the totally non-oriented tin powder sample.
