Project summary

Coatings of metals (Ti, Zr, Ac) nitrides are being applied in many fields of the engineering industry and especially in devices and apparatus functioning under higher temperatures and in corrosive media.

The proposal deals with investigations of processes linked with simultaneously deposited upon metals (steel and related compounds) coatings of titanium nitride and carbide. Conditions for obtaining the N and C compounds and some of its properties will be studied as well.

Particular attention will be paid to the variation of certain regularity of X and Y indexes within the TiCxNy formula according to the thickness of the coating. There will be elaborated basic principles of the technological process for obtaining wear-resistant coatings used in the metal treatment (cutting, drilling, etc.).

The key point of the project is the isotopic modification of N and C compounds by stable isotopes C-12, C-13 and N-14, N-15. It may be foreseen that the use of various proportions of these isotopes while producing desirable materials and coatings and study of their electric and thermal characteristics can contribute to discover new interesting physical and chemical parameters of compounds based on carbon and nitrogen titanates as well as to open good prospects of their utilization for producing isotope-modified coatings (it is known that they may have ultrahigh thermal conductance).

Within the framework of the Project there will be undertaken and performed the following activities:

  • To carry out investigations focused on obtaining N and C compounds based coatings by the laser-plasma technology (methods of plasma-chemical, laser, cathode-ray and layers' plasma deposing);
  • To study conditions for depositing isotope-modified coatings upon the steel substrates while plasma-chemical reactions take place (methods of X-ray-phase, X-ray-structural, optic, electron-microscopic, Auger- and mass-spectrometric analysis);
  • To explore how the chemical and isotope composition of compounds based on N and C compounds influences their deposition kinetics and coatings structure (methods for measuring thermo-physical, mechanical and electro-physical parameters);
  • To study structural, physical-mechanical and physical-chemical parameters of isotope-chemical coatings upon samples made of different steels;
  • To prepare the physical model of isotope effects in compounds based on N and C compounds and to work out methods for obtaining their coatings upon steel surfaces.

The Project covers 5 main tasks and 12 subtasks, its duration is 24 months and estimated total cost $120400.

The executive team is completed of researchers and specialists having a great experience in carrying out research activity focused on the fulfillment of State commissions aimed at achieving military goals.

Within the scope of activities of the project proposal there is foreseen the following collaboration with the Foreign Collaborator: information exchange in the course of project implementation; provision of comments to the technical reports (quarterly, annual final, etc.), submitted by project participants to the ISTC; share of use of certain equipment and/or test and sample materials; cross-checks of results obtained in the course of project implementation; testing and evaluation of equipment/technologies developed in the course of the project; participation in technical monitoring of project activities performed by ISTC staff; participation in technical checks of activity within the project carrying by the ISTC staff; conduction of joint seminars and workshops.

There will be obtained theoretical results and experimental data as well as prepared samples for performing their coating and carrying out full-scale tests of physical-chemical and mechanical strength characteristics.

Scientific results will be published in renowned international editions. There is also foreseen the preparation of patent applications.
