Project summary

The material treatment by concentrated pulsed fluxes of energy (high-power ion and intense current electron beams, high power pulsed microwaves, wear X-ray, a.o.) for modifying surface layers of wide-rang parts and cardinal improvement of their properties is the most perspective area of the present-day science and engineering. Previously such technologies were mainly used for military goals, however, the results of last researches, performed by the leading world-known scientists (G. Wolf, G. Dearnaly, D. Rej, N.Moncoffre, V.Shulov, A.Ryabchikov, G.Remnev, ect.) showed that the irradiation of various alloys firstly by ion and electron beams ensures the solution of a large number of applied problems in machine-building, gas-petroleum industry, civil aviation, motor-car building, medicine etc. In this connection, the main objective of the present project is the development of fundamental and technological bases for surface modification processes of dental and body implants from the most advanced bioinert materials (titanium and zirconium allots, high-alloyed steels, composites) with the use of the following treatment by high-power ion and intense current electron beams (carbon, ions and protons energy - E=100-600 keV, ion current density in a pulse - j=40-500 A/cm2, pulse duration - t=50-100 ns, electron energy - 20-150 keV, energy density – W=1-50 J/cm2, pulse duration - t= 0.7-20 ms), by high-power pulsed microwaves (wave length - l=10 cm, t=200-500 ms, power density - P=103-106 W/cm2), depositing vacuum-plasma coatings with the separation of droplet fraction and arc-pulsed implantation of various ions (E=30-80 keV, j=0.5-5.0 mA/cm2, t=20-400 ms, frequency - f=10-30 Hz, irradiation dose - D=1016-1019 ion/cm2). The project participants were pioneers in the area of studying the complex ion-beam and electron beam treatment effect as well as the effect of ion implantation upon the surface state and superalloy properties. The results of these researches showed, that the similar integral technologies allow to achieve the high level of a whole set of GTE blades and disks operating characteristics (fatigue strength and stress rupture, ductility after the thermal exposure, heat resistance, salt corrosion and sand particle erosion resistance, friction and wear) the relatively not great expenses for the equipment and irradiation (the cost of technological accelerators in Russia doesn’t exceed 300000 $ and irradiation expenses for 1m2 of a surface with the account of the staff salary, water supply and power cost – 5 $). The project participants posses Temp- M, Lutch, Vera, Raduga-5, Gesa accelerators and the installation of high-power pulsed microwaves, which are the basic ones for the realization of the developed complex technologies. The use of the latter ones for treating various ultra dental and body implants allows to solve the most complicated implantology problems: the improvement of short-term and fatigue strength, bioinertness and biotolerance; the osteointegration process acceleration and hence, the cardinal implant reliability and durability improvement. The basis of such prediction are the possibilities for creating the controlled surface microrelief, applying and following synthesizing coating materials, producing layers with the amorphous structure at the rapid solidification and the controlled grain size in the near–surface zones.

In order to achieve the pre-set goal, a whole number of problems of fundamental methodological and applied nature should be solved and they cover such areas as the development of methods for selecting the optimum irradiation conditions and studying thin surface layers of multicomponent materials; simulation of processes occurring in surface layers with the following irradiation and heat treatment; study of the irradiation conditions effect upon the surface layers state and implant properties along with researching the texture and crater formation phenomena, rapid solidification, ablation and plasma formation, coating condensation out of the droplet phase. The obtained data will give a possibility not only to explain the study and test results, but also to use them for other materials and parts. Besides, the successful Project fulfillment will be the basis for developing the commercial production technology of dental and body implants with various functional designations. This stage will secure the complete conversion of the project organizations-participants with minimum state budget expenses and their scientific potential retention. The role of foreign collaborators is the extremely important at the stage of the project fulfillment. It concerns not only the discussion of obtained data, the work plan correction and joint publications but also the target irradiation with the use of Heidelberg, Marburg and Karlruhe accelerators, carrying out some researches and tests, preparing specimens of the materials, which are of interest for collaborators, and comparing the material properties after ion-beam and electron – beam irradiation with their Russian analogue properties.

The planned Project work volume can be made only at the complete loading of all four participants-organizations (VIAM, NIKIMT,MISIS, NIIYaF) for two years with attracting some specialists from the other organizations.
