Abstract
The invention relates to an anti-friction coating () made from a tin-based alloy which, in addition to tin, contains at least one other element from the group comprising antimony and copper, optionally lead and/or bismuth, and optionally at least one element form a group comprising zirconium, silicon, zinc, nickel and silver, and the proportion of antimony is at most 20% by weight, the proportion of copper is at most 10% by weight, the total proportion of lead and bismuth is at most 1.5% by weight, the total proportion of copper and antimony is at least 2% by weight and the total proportion of zirconium, silicon, zinc, nickel and silver is at most 3% by weight, and tin is present bonded in the form of inter-metallic phases and freely as a tin phase with beta-tin grains. The tin grains with a beta-tin structure have a mean size in μm which is calculated on the basis of the formula K=A/(S+3*C+O), and the tin grains with a beta-tin structure in the tin-based alloy in any event have a mean grain size of at least 2.5 μm.
