Abstract (en)
[origin: FR2777910A1] Carburizing or carbo-nitriding of metal or metal alloy components involves contacting the components, at least during a carbon enrichment phase, with an enriching atmosphere made up of hydrogen and carbon monoxide. The CO/H2 ratio of the atmosphere is different by 1/2.
