Abstract
A method of surface-hardening mechanical parts of ferrous metals by introducing into the surface layers of the treated parts a plurality of elements chosen from the groups consisting of nitrogen and carbon nitrogen, carbon and sulphur, nitrogen, carbon, sulphur and phosphorus in which said parts to be treated are immersed in a bath of molten salts at a temperature of 450 DEG to 600 DEG C., said bath being of the kind comprising CO3<--> and CNO<-> ions on the one hand and on the other hand alkaline ions comprising Li<+>, K<+> and Na<+> ions. The bath may further comprise sulphur anions chosen from the group consisting of S<-->, SO3<--> and S2O3<-->, and also PO3<-> phosphorus ions. A regenerating agent comprising urea is further introduced into said bath in order to convert excess CO3<--> ions to CNO<-> ions, and an apparatus is described for carrying this method into effect.
