• THE COMPATIBILITY FACTOR IN MATERIAL SCIENCE OF MIXED ENGINEERING NANOBLENDS

    Machines. Technologies. Materials., Vol. 12 (2018), Issue 8, pg(s) 341-343

    Features of the structure of blends obtained by thermomechanical blending of thermoplastic components with different molecular structure are considered. The possibility of formation of structures with different levels of ordering (from heterophase structure with a pronounced boundary between the components to the macrogomogeneous structure with high compatibility of matrix and modifying components) is shown. Under injection of nanosize particles with different chemical composition into the blends, a synergistic effect of simultaneously increasing the parameters of tensile stress-strain and tribotechnical characteristics of items and its resistance to thermal oxidation is achieved. Nanosize particles in the active state perform the function of a physical compatibilizer, forming a cross-linked structure with physical bonds in the volume of the composite. The engineering nanoblends with increased performance parameters have been developed.

    MULTILEVEL MODIFICATION IN MATERIALS SCIENCE AND POLYMER NANOCOMPOSITES TECHNOLOGY

    Machines. Technologies. Materials., Vol. 11 (2017), Issue 10, pg(s) 485-489

    This paper describes directions of realization of the multilevel modification principle in materials science and technology of polymer composite materials based on thermoplastics. It is shown that the introduction of nanoscale particles of different structures and production technologies into the composition of the composite makes it possible to transform the structure at various organization levels, which leads to the achievement of a synergistic effect of increasing the parameters of deformation-strength, tribotechnical characteristics and resistance to the action of thermal-oxidative medium. One of the perspective technologies of the nanomodifiers introduction into the composite material is the diffusion treatment of components and products in precursor solutions. Mixture of composite materials with increased parameters of performance characteristics for use in engineering, chemical and mineral resource industries have been developed.

  • NANOCOMPOSITE MATERIALS BASED ON THERMOPLASTIC BLENDS FOR THE TECHNOLOGICAL EQUIPMENT WITH A LONG SERVICE LIFE

    Materials Science. Non-Equilibrium Phase Transformations., Vol. 3 (2017), Issue 3, pg(s) 92-94

    The composite materials based on polymer and oligomer blends with different thermodynamic compatibility have been developed. It is shown that for polymer and oligomer blends of products formed as result of the thermogasdynamic synthesis of fluorine-containing compounds, the ability of oligomeric matrix to multiply deformation and alternating transfer is the most important. In polymer-polymer systems formed in a melt by various technologies the most important factor is the structure of the boundary layers determining the parameters of the stress-strain and tribological characteristics of the composites. The effect of physical compatibilization during the introduction of nanoscale metal-containing and carbon-containing particles into the blend compositions has been established. This effect promotes the thermodynamic compatibility and resistance to the action of thermal-oxidative medium on composites.

    Innovations in Discrete Productions, Vol. 4 (2016), Issue 1, pg(s) 20-21

    Investigated the features of the structure of the thin-film coatings based on polymeric and oligomeric matrix formed by dipping, spraying or rubbing. It was found a significant effect of energy substrate parameters and components of the coating on the mechanisms of interfacial interactions that determine the parameters of strength, tribological and protective coatings. The active layer morphology of the surface of the substrate formed by mechanical, laser or chemical influence, characterized by the presence of low-dimensional components of different habitus, which affect the energy and mechanical component adhesive strength. By managing service parameters of composite material components on the basis of polymeric and oligomeric matrix manages to change the mechanisms of formation of coatings on metal substrates of carbon steels and non-ferrous metals. Coatings based on the thermal ablation of PTFE products are effective in the process of running heavy-duty friction units and their operation at reversing the motion. Installed effect Nanophase formation regions in the volume of the coating, which help to increase their durability in friction without external supply of lubricant.
