2. Carbon monoxide- and hydrocarbon-based atmospheres
2.1 Atmosphere generation
In the case of carburizing with the CO molecule in a CO – H 2 mixture, the atmosphere is generally produced in one of two ways either outside the furnace from the endothermic generator technique, or directly inside the furnace from the instillation of organic liquid.

Endothermic generators are chemical reactors heated to around 1,050°C in which an oxidation of natural gas in the absence of air, results in an atmosphere essentially composed of carbon monoxide, dihydrogen and chemically inert dinitrogen. Figure 2...
