An arc sprayed functional layer (2) of reduced friction, produced from a spraying material, the functional layer (2) having a hardness in the range of 400 to 850 HV 0.1 and comprising the following alloying constituents: carbon 0.45% by weight to 0.8% by weight,manganese 0.8 to 2% by weight,molybdenum 0.4 to 1.3% by weight,chromium ≧10% by weight,nickel 0.01% by weight to 1% by weight,sulfur 0.01% by weight to 0.035% by weight,copper 0.01% by weight to 0.35% by weight, and optionally: silicon 0.01% by weight to 1% by weight,vanadium 0.01% by weight to 0.3% by weight,phosphorus 0.01% by weight to 0.045% by weight,aluminum at most 0.01% by weight, and the remainder iron and unavoidable impurities in each case relative to a total weight. 3. The functional layer (2) as claimed in claim 2, wherein the functional layer (2) has interstitially dissolved iron nitrides and chromium nitrides, the nitrogen portion of the alloy being a proportion of 0.01 to 2% by weight relative to a total weight. 4. The functional layer (2) as claimed in claim 2, produced by melting a wire-form spraying material (4) formed at least with carbon as microalloy such that upon solidification of the spraying material a functional layer (2) having a hardness in the range of 400 to 850 HV 0.1 is produced, the following alloying constituents being provided in the wire-form spraying material (4): carbon 0.7% by weight to 1.2% by weight,chromium 12% by weight to 20% by weight,manganese 0.8% by weight to 2% by weight,molybdenum 0.4 to 1.3% by weight,nickel 0.01% by weight to 1% by weight,sulfur 0.01% by weight to 0.035% by weight,copper 0.01% by weight to 0.4% by weight, and optionally: silicon 0.01% by weight to 1% by weight,vanadium 0.01% by weight to 0.3% by weight,phosphorus 0.01% by weight to 0.045% by weight,aluminum at most 0.01% by weight, and the remainder iron and unavoidable impurities in each case relative to a total weight in an arc (5) and depositing the melt as a functional layer (2) on a substrate (1), with nitrogen being used as process gas. 5. The functional layer (2) as claimed in claim 4, wherein the wire-form spraying material (4) is melted in the arc at a melting power of at least 9000 W. 6. The functional layer (2) as claimed in claim 4, wherein the wire-form spraying material (4) is conveyed at a speed of at most 12 m/s and sprayed to form a jet of melted particles, wherein the jet of melted particles is sprayed at a speed of at most 20 m/s. 7. The functional layer (2) as claimed in claim 4, wherein residual compressive stresses are generated in the functional layer (2) by temperature control in a heating oven or by local inductive heating. 8. The functional layer (2) as claimed in claim 4, wherein the wire-form spraying material (4) is melted in the arc at a melting power of at least 9000 W with a current intensity of at least 250 A and/or a voltage of at least 36 V.
