Karazin popup.description2 Investigation subject: Nano-scaled coatings obtained by means of vacuum arc deposition method of different compositions and structures are under investigations. Objective: Properties investigation of nanolayered coatings with different composition and structure obtained utilizing different technological charts and their influence on the tribological properties of such coatings. Investigation method: Analysis and generalization of literature experimental data concerning the influence of formation conditions on functional properties most used in practice vacuum arc coatings. Experimental investigation of nanolayered coatings with different composition and structure. Properties investigation was carried out on samples made of 12ХФ1 steel specially pepared for tribological testing using outline named "surface-roller". Coatings of different composition and structure were obtained using several technological charts during previous project stage execution. Were defined such coatings characteristics like thickness, thickness correlation of different layers, hardness, surface microhardness before and after deposition, coatings nanohardness and Young modulus. For the Ti-Al-N system were investigated type and lattice parameter and concentration rates Ti to Al. Investigations of tribological properties were carried out in the media of fuel TC-1 utilizing discreet weight loading schema. Bronze Бр.О10С2Н3 with different surface modification technologies was used as a rider. It was shown influence of bronze surface modification, i.e. condition of contacting surface in tribological situation, direction of coatings composition and structure for achievement better tribological indexes may change drastically. Under contact in tribological situation with unmodified bronze surface better tribological properties have coatings with layered structure like "hard compound-metall" for example MoN-Mo. In tribological situation using modified bronze surface better tribological properties have harder coatings on the base of one or fewhard compounds (Ti-N, Mo-N, TiN-AlN). Best tribological properties among this coatings wear as well friction coefficient were shown by nanolayered TiN-AlN coatings. Carried out investigations show that implementation of various technological charts together with right choice of materials in coating composition and layered structure deposition parameters make possible improve tribological properties. R&D results are used in technological development and the further researches directed on creation new functional nanostructured materials and methods of their formation. Predictive assumptions concerning development of researching object - optimization of processes of reception nanocoatings with prescribed set of characteristics formation process optimization.
