FIELD: machine building.

SUBSTANCE: invention relates to sliding element used, for example, as a plain bearing in internal combustion engines, plain bearing of crankshafts, piston rings or piston skirts. A sliding element comprises a bottom layer and at least one layer made from the sliding facilitating material applied onto the bottom layer. The layer of sliding facilitating material consists of varnish containing at least one binder able of linking or at least one high-melting thermoplastic material, and containing Fe₂O₃. The share of Fe₂O₃, in terms of total volume of material in the sliding facilitating layer, amounts to 0.1 to 15% by volume. The microroughness of the bottom layer R_z falls within the range from 1 to 10 mcm.

EFFECT: development of a sliding element with its coating subject to high loads having a plastic matrix containing Fe₂O₃ and being highly adhesive to the bottom layer at simultaneous increase of maximal load.
