Abstract-Multicomponent hard coatings based on nitrides of Si doped transition metals have been pro duced by vacuum-arc deposition with the use of a RF generator and separation of an ion-plasma flux. Physico mechanical and tribotechnical characteristics of coatings have been studied. The possibility of their use as efficient protective coatings has been shown. DOI: 10.3103/S1063457614010055Keywords: protective coatings, vacuum-arc deposition, nitrides of metals, cutting tools. INTRODUCTIONOne of the priority directions of the modern science and technology is the development of new materials on the basis of multicomponent alloys, nanocomposite coatings, and analysis of their physico mechanical and tribological characteristics [1,2].To produce multicomponent and multilayer coatings, the ion-plasma deposition methods are most used in the industry, in particular, magnetron sputtering [3] and vacuum arc deposition [4]. The use of ion-plasma methods makes it possible to produce multicomponent coatings of different materials by mixing plasma streams from several sources or by sputtering of a cathode, which contains various components in its compo sition. Of greatest scientific interest are the methods, the use of which makes possible the formation of multi component coatings by conventional devices with one cathode containing necessary components in required ratios. The advances of technologies of applying nanocomposite coatings by ion-plasma methods require a further improvement of the known sputtering systems and development of fundamentally new devices [5,6]. Synthesized multicomponent coatings have high operational characteristics due to the stabilities of the struc ture and composition, which are characterized by the minimum Gibbs energy.Of refractory compounds that demonstrate high functional characteristics nanocrystalline composites pro duced as interstitial solid solutions based on nitrides of titanium, zirconium, hafnium, silicon, etc. take up a special place [7,8].The aim of the present study was to develop superhard multicomponent nitride systems based on solid solu tions produced by sputtering all metal cathodes using a vacuum-arc deposition from a separated beam and RF low energy ion treatment and to study physico mechanical properties of the resulting coatings. The use of separated ion-plasma flux will make it possible to practically get rid of a drop fraction in the coatings formed.

Current paper presents the results of investigating of nanostructured cathode arc vacuum evaporation coatings, based on (Ti, Hf, Nb, Si)N. Several methods of the structural and elemental analysis were used: proton microbeam, nano-and micro-electron beam, X-ray diraction analysis. To determine tribological properties (scratch resistance, adhesive and cohesive strength) of the coatings, scratch testing were conducting. Inuence of thermal annealing at temperatures 300, 500, 800, 1000• C on elemental composition, microstructure, residual stress, phase composition, proles of atomic distribution in the coatings were investigated.

Проведён сравнительный анализ структуры и свойств покрытий на основе тугоплавких соединений в зависимости от условий осаждения (темпера-туры и потенциала подложки, парциального давления рабочего газа). Выявлены общие закономерности для твёрдых и сверхтвёрдых нано-структурных (нанокомпозитных) покрытий, состоящие в наличии столб-чатой структуры и текстуры роста. Показано, что для карбидных и нит-ридных покрытий переходных металлов имеют место два возможных направления роста <111> и <100>, для диборидов переходных металлов таковым является <0001>. Проведён анализ влияния структурного со-стояния на изменение физико-механических характеристик нанокри-сталлических покрытий на основе нитридов, боридов и карбидов пере-ходных металлов.Ключевые слова: тугоплавкие соединения, структура, твёрдость, потен-циал подложки, парциальное давление.Проведено порівняльну аналізу структури та властивостей покриттів на основі тяжкотопких сполук, залежно від умов осадження (температури і потенціялу підложжя, парціяльного тиску робочого газу).
