of atmosphere solutions can ensure that your special atmosphere requirements can be fully satisfied. Nitrogen, typically the main atmosphere component, provides the inert base that prevents undesirable reactions from occurring. Often, a reducing agent such as hydrogen or a hydrocarbon is added to adjust atmosphere reducing potential.

Nitriding - Wikipedia

Since nitrogen ions are made available by ionization, differently from gas or salt bath, plasma nitriding efficiency does not depend on the temperature. Plasma nitriding can thus be performed in a broad temperature range, from 260 °C to more than 600 °C.

Getting the Right Protective and Carburizing Atmosphere

When using nitrogen methanol in a furnace at the typical operating temperatures, the methanol immediately dissociates into carbon monoxide and hydrogen. When mixed, 33% methanol (CH 3 OH), 66% nitrogen, and endothermic equivalent atmosphere are formed in the furnace. When using sensors and when the base atmosphere in the furnace is under equilibrium conditions, these assumptions must be consistent, known, and repeatable.

The atmospheres used can be nitrogen, argon, exothermic gas, endothermic gas, nitrogen-methanol, ammonia, dissociated ammonia, steam, or controlled mixtures of more than one gas. One common atmosphere furnace arrangement is the bell type, where the heating system is contained in a lifting box, or cylinder shaped shell, which is then sealed to a base holding the work load and containing the atmosphere seal.

"Carbon control" is the automatic "in situ" control of carbon potential. Carbon potential is the ability or potential of the furnace atmosphere to either carburize or decarburize steel. You add carbon to the steel when you carburize and you subtract carbon when you decarburize. All steel has some carbon in solution in the steel.

Strategies for efficient operation of furnaces using nitrogen

Abstract. To minimize the cost of operating furnaces using protective atmospheres formed from nitrogen plus a reducing gas, both the flow rate of atmosphere gas and the amount of added reducing gas must be controlled. Optimum parameters for steady state operation are determined by (1) the type of atmosphere desired— nonoxidizing (but decarburizing),
