Abstract (en)
[origin: WO2010130484A2] The invention relates to a method for carbonitriding at least one metal part in which the metal part is heated to a treatment temperature in a heating phase (1), is nitrided with a nitrogen donor gas in at least one nitriding phase (2a-2d) and is carburized with a carbon donor gas in at least one carburizing phase (3a-3d). Said method is characterised in that the first nitriding phase (2a) begins once the heating phase (1) has finished and prior to the beginning of the first carburizing phase (3a).
