Abstract: A method for producing a rolling bearing component with a carbon gradient, at least in the region of its outer layer, wherein molten metal is sprayed onto a carrier in a spraying process, the carbon content of the metal to be sprayed on being varied during the spraying operation.

Abstract: A rolling bearing having an outer ring, an inner ring and rolling bodies which roll on raceways of the rings. The raceway of the inner and/or outer ring and/or the surface of the rolling bodies has a burnishing layer, and the inner and/or the outer ring and/or the rolling bodies are formed of a steel which has a hardness of at least 58 HRC at least below the burnishing layer and which, at least below the burnishing layer, has: a nitrogen content at least in the marginal layer of 0.03-0.8%, the nitrogen being at least partially dissolved, a carbon content at least in the marginal layer of 0.1-1.2%, a nickel content of ?0.4%, a silicon content of 0.2-1.0%, a chromium content of ?1.0%, a sulfur content of ?0.008%, an oxygen content of ?15 ppm, and a titanium content of ?50 ppm.
