Mikroindentace těles s vazkopružnou odezvou
Minster, Jiří ; Micka, Michal ; Bláhová, O.
This paper presents some results related to the introductory part of a project aimed at identifying the time-dependent mechanical characteristics of viscoelastic materials on the basis of microidentation data.
Povrchové a mechanické vlastnosti organicko/anorganických nanokompositních nátěrů
Špírková, Milena ; Bláhová, O. ; Farkačová, T. ; Benešová, J.
Surface hardness of transparent colorless epoxy-based organic-inorganic nanocomposite coatings was investigated by atomic force microscopy, nanoindentation and the Persoz pendulum test. The influence of mechanical properties on the measured surface characteristics is discussed.
Depozice a charakterizace nanostrukturních diamantů podobných uhlíkových vrstev obsahujících oxid křemíku
Buršíková, V. ; Zajíčková, L. ; Franta, D. ; Janča, J. ; Buršík, Jiří ; Klapetek, P. ; Bláhová, O. ; Peřina, V. ; Navrátil, V.
The aim present work was to deposit and study nanostructured diamond-like carbon coatings with silicon-oxide content on different substrate materials.The variation in SiOx content enabled to minimize the intrinsic compressive stress in coatings.The influence of the coating/substrate interface properties on the results of the indentation tests and its dependence on the coating thickness was studied.Complex analysis of the maesured coating/substrate response was done and the existing models for substrate influence were tested.
Instrumentovaný indentační test v nano- a mikroměřítku
Buršíková, V. ; Buršík, Jiří ; Bláhová, O. ; Dušek, J. ; Navrátil, V.
Several materials were chosen to span a wide range of hardness and structure,including pure copper,nickel,titanium,cadmium,zinc and silver.Nanoindentation hardness and microhardness values in wide interval of loads,measured by DSI method and classical Vickers microhardness method were compared in view of indentation Size Effect.
Povrchové vlastnosti nanokompozitů silika/epoxy nátěrů
Bláhová, O. ; Špírková, Milena ; Farkačová, T.
This contribution deals with the determination of mechanical properties of hybrid organic-anorganic epoxy-based coatings prepared from functionalized organosilicon precursors, oligomeric di- or triamines and colloidal silica particles or montmorillonite.
Mechanical properties of organic - inorganic nanocomposites coatings
Farkačová, T. ; Bláhová, O. ; Špírková, Milena
The contribution deals with the determination of tribological properties of hybrid organic-inorganic epoxy-based coatings on tribometer by method pin-on-disc. The friction coeffiecient and wear resistance were monitored. Examined specimens were prepared from functionalized organosilicon precursors, oligomeric di- or triamines and colloidal silica particles. The products are the result of two independent reaction mechanisms: the sol-gel process and the epoxy-amine addition reactions.
