“…Samples for research in the form of parallelepipeds with dimensions 10h30h30 mm 3 were cut from the bar steel P6M5 in a position to supply. Before electrolytic-plasma processing blanks were subjected to common heat treatment for this type of steel: quenching from 1230°C in the oil and the substequent triple tempering at 560°C (duration of each leave is 1 hour, cooling in air) [8]. Then the samples were polished from all sides to a depth of 1 mm.…”

Microhardness of nitrated and carbonitriding in electrolyte plasma steel Р6М5 surface layers are investigated in the research. It shows perspectiveness of the cutting tool electrolyte-plasma treatment technology. Operating conditions for the technology realization are defined. It was also indicated the desired content of components in saturating mixtures by nitriding and carbonitriding. Comparative research of structure, phase composition of fast-cutting P6M5 steel modified surface layers after electrolyte plasma treatment was carried out by scanning-electron and light microscopy, and X-ray structure analysis methods. The way of electrolytic plasma nitriding in cathodic mode, to provide fast-cutting steels which allows for modification the surface and high kinetic efficiency the process diffusion saturation. It was established that as a result of nitriding and nitrocarburizing in plasma electrolyte has been a significant increase in microhardness in the surface layers of steel Р6M5.

“…Different techniques of surface strengthening are actively used for increase of service life of cutting tools. Among these techniques, the methods of coatings deposition are of special interest [1][2][3]. CVD method (Chemical Vapour Deposition) consists in condensation of a metal at a substrate after its reduction from decomposed chemical compound [4][5].…”

Abstract. СVD chromium coatings are evaporated on steel substrate from chrome-organic compounds. For crystallization with forming of nano-particles of chromium carbides, subsequent heating (annealing) of tool steel with hybrid coatings is carrying out. Significant increase of micro-hardness of the coating up to 27000 MPa is observed due to the dispersion strengthening. Optimal annealing parameters (temperature and duration) are determined, which maximally strengthen the coatings and increase their adhesion to the steel substrate.

We have investigated the bonding and adhesion of the TiN(001)/fcc-Fe(111) interface with and without defects using density functional theory. Substitutions in Fe, vacancies and impurities in TiN as well as the influence of vertical stress are studied. The performed bonding analysis shows that the main interaction between Fe and TiN originated from the Fe–N bonding, regardless of the specific set-up. For the ideal TiN(001)/fcc-Fe(111) interface, a complete separation of the interface is preferred to any transfer of iron atoms to the TiN surface. The presence of Ti and N vacancies or alloying elements at the interface further promotes this trend. Application of stress to the system lowers sliding barriers along the Tin/Fe interface.
