The present invention relates to an anti-fretting layer (5) for multi-layer flat bearings (1), which comprises, in addition to copper, germanium, tin, indium, zinc, nickel, cobalt, bismuth, lead, Silver, consisting of a copper alloy containing at least one element selected from the group of antimony and inevitable impurities resulting from the manufacturing process, wherein the sum of the alloying elements is at least 1% by weight and at most 30% by weight There are copper mixed grains formed from copper and at least one element, the copper mixed grains being oriented according to the orientation index M {hkl} of the following formula (I): [Wherein the lattice plane set {hkl} has a value less than 3.0, where I {hkl} represents the X-ray diffraction intensity for the {hkl} lattice plane of the anti-fretting layer and I0 {hkl} is completely unoriented X-ray intensity of the copper-powder sample (ICDD PDF 00-004-0836)] |
