In a process for carbonitriding metallic components ( 1 ), provision is made of at least one carburization phase (C 1, C 2 ), in which the metallic component ( 1 ) is carburized with a carbon-donating gas. In addition, provision is made of a nitriding phase (C 1, C 2, C 3 ), which is assigned to the carburization phase (D 1, D 2 ) and precedes the carburization phase (D 1, D 2 ). Here, in the nitriding phase, the metallic component ( 1 ) is nitrided by means of a nitrogen-donating gas at least superficially at at least one surface region ( 4 ) of the metallic component ( 1 ). It is thereby possible to avoid an excessive concentration of carbon, and therefore component failure is prevented and it is possible to dispense with costly remachining steps, e.g. grinding. |
