1. A sliding element, comprising:
a metal substrate layer; and
a coating which is applied thereto and which comprises at least one anti-friction cured lacquer layer of a polymer resin matrix containing functional fillers in the form of mixed-phase oxides having a Rosiwal grinding hardness of below 55 and present at a proportion of 0.1 to 15% by volume of the cured lacquer layer; wherein the mixed-phase oxides have a D50 mean particle size in the range of 0.05 to 2.0 μm; wherein the metal substrate layer comprises a metal support layer or a metal bearing layer or a steel support layer and a metal bearing layer, wherein the coating is applied to an exposed layer of the substrate layer formed of Cu, Al, Ni, Sn, Zn, Ag, Au, Bi or Fe alloy.
