Experiments were conducted using two different configurations: one to collect and analyze species probed primarily in the bulk of the plasma, at a position distant from the heated sample; and the other to collect and analyze species very close to the reactive surface of the heated sample in such a way as to allow the analysis of lower concentration or residence time species, formed at the plasma/sample surface interface. Use of these configurations contributed to the investigation of the physical chemistry involved in the above plasma processes. An exchange the expected stoichiometry in ammonia formation in N2/H2/CH4 mixtures, with a shift towards higher nitrogen consumption, is observed and is interpreted an indication of nitrogen removal from the surface associated with ammonia and carbonitrides/nitrides formation. The present results point to the existence of a correlation between the nitrocarburizing and nitriding processes with respect to the formation of non-stoichiometric ammonia as a product.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://scielo.figshare.com/articles/Mass_Spectrometry_Study_of_Ammonia_Formed_During_Plasma_Nitrocarburizing_and_Nitriding_Processes/6832847","contentUrl":null,"metadataVersion":3,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isA
