When only an endothermic carrier gas was used, the output voltage of each probe was essentially the same. However, when enriching gas (natural gas) was added to the furnace the probes produced different voltage outputs. This probe output ... Extensive investigation showed that the electrodes catalyze reactions of the common enriching gases used for carburizing steel parts. These catalyzedanbsp;...
