METHOD FOR PRODUCING ROLLING BEARING COMPONENTS AT LEAST PARTIALLY MADE OF A SILICON CARBIDE MICROSTRUCTURE AND ROLLING BEARING COMPONENTS PRODUCED ACCORDINGLY

摘要

The invention relates to a method for producing rolling bearing components at least partially made of a silicon carbide microstructure, wherein a rolling bearing component is formed from a blank made of a material containing carbon, and in a first step the rolling bearing component made of the material containing carbon is produced substantially according to the desired final shape and/or final dimensions thereof, and subsequently the rolling bearing component is infiltrated with a precursor sol containing silicon and carbon or is coated at least in some areas with a silicon dioxide granulate rich in carbon and is baked at least once in a protective gas atmosphere in a treatment chamber, wherein the material of the rolling bearing component is partially or completely converted into silicon carbide by the infiltrated precursor sol or the silicon dioxide granulate gives off gas containing silicon carbide, wherein said gas penetrates the rolling element bearing component and partially or completely converts the material containing carbon into silicon carbide. During the conversion, the rolling bearing component is moved in the treatment chamber in such a way that the position of the rolling bearing component in the treatment chamber changes continuously.
