The invention relates to the use of a super-slippery thin-layer film or coating for enhancing the lubrication capacity of a part to be subjected to great friction and wear. The film of the invention for improving the lubrication capacity of parts to be subjected to important friction and wear includes at least: a layer (3) of a hard material selected from titanium nitride (TiN), chromium nitride (CrN), titanium carbide (TiC), chromium carbide (CrC), tungsten carbide (W2C) and tungsten carbide-carbon composites (WC/C), alumina (AI2O3), molybdenum sulphide (MoS2), and materials of the hydrogenated amorphous carbon type (a: CH), the layer including on one surface thereof a series of dips and protrusions; and a layer (4) of an oleophilic material. The invention can particularly be used in the field of mechanics.
