Claim Text:
1. An arc sprayed functional layer ( 2 ) of reduced friction, wherein said functional layer is formed by arc wire spraying of 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: 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.
