Obtaining the Controlled Sulphonitrocarburized Layer Phase Compositions, by the Variation of the Solid Powdery Medium Components

Abstract:

Simultaneous saturation of the metallic surface with sulphur, nitrogen and carbon - named sulphonitrocarburizing (SNC) process - may be carried out in a multitude of variants, differ in media state of aggregation which provide the elements in native state, or differ in phase composition. The most commonly used media in SNC process are liquid or gaseous and from standpoint of phase composition, there are media made of compounds generator of the cyanides, representing important source of carbon and nitrogen, and as a sulphur source, may be used iron sulphide, sodium sulphide, sodium thiocyanides or ammonium. Carbamide/urea (CON2H4) it is frequently used in the media composition met in nitro-carburizing or carbo-nitriding process, alongside being added carbonates (sodium or potassium carbonate), thus resulting in cyanides (primary sources of the elements helping superficial saturation of the metallic products), as a result of the reactions which take place at the operating temperature of process. The medium toxicity decreased, based on carbamide used in nitrocarburizing and in particular, SNC process, being possible by carbonates replacing with ammonium chloride. This paper quantify the possibility of using solid powder mixture constituted of carbamide, in order to achieve SNC process of the iron matrix and effects quantification varying the percentage of the solid powdery mixture, so that it becomes possible to control the layer phase composition, by modifying the phase composition of the powder mixture used in thermo chemical processing.
