Kolina T.P., Tarasov A.N., Bryukhanov V.V. THE INFLUENCE OF COMPOSITION, STRUCTURE AND SURFACE CONDITION ON THE STRUCTURE AND THE PROPERTIES OF DIFFUSION LAYERS DURING THE HIGH-TEMPERATURE NITRO CEMENTATION OF STEELS IN THE ACTIVATED CHARCOAL MIXTURESThe authors carried out studies and generalized the experience of the selection of the optimum conditions for the preparation of small tool, rigging and structural components made of steels of ferrite, martensite and carbide classes for the high-temperature cementation in the new activated charcoal compositions. They established the real flow charts of working, which make it possible to form wear-resistant carbide diffusion layers with the thermochemical treatment in the compositions on basis of charcoal with the introduction of the nitrogen-bearing components of carbamide and trilon-B.Key words: nitro cementation, steel of carbide class, carbomide, diffusion layers, branchy and globular carbides.
