We have analyzed the surface of a plasma three-dimensional capillary-porous (TDCP) Ti coating with an additional bioactive hydroxyapatite coating formed by microplasma oxidation (MPO). Scanning electron microscopy (SEM) was used to analyze the open porosity of these composite coatings. The surface of the TDCP Ti coating consists of ridges and valleys. The main porosity of the TDCP Ti coating is concentrated within the volume of valleys and reaches 43%. The presence of macro- and micropores 0.08–600 μm in size makes TDCP Ti coatings promising for using in a variety of fields, including as the surface coatings of intraosseous implants.

An analysis of the surface of a plasma three-dimensional capillary-porous (TCP) Ti coating with an additional bioactive hydroxyapatite coating formed by microplasma oxidation (MPO) has been performed. Scanning electron microscopy (SEM) analyzed the open porosity of these composite coatings. The surface of the TCP Ti coating consists of ridges and depressions. The porosity of the TCP Ti coating of the depressions reaches 43 %. The presence of macro- and micropores with a size of 0.08 – 600 µm makes the TCP Ti coatings promising for use in a number of areas, including on the surface of intraosseous implants.

A computer study of the morphological characteristics of the AFM image of a self-organized system of surface hillocks in CZ n-Si (100) samples doped with zinc under conditions of hot implantation and oxidized at elevated temperatures is performed. Topological studies of the sample surface are carried out under ambient conditions using a scanning tunneling microscope in the atomic-force mode. Computer analysis of the AFM images of the surface is carried out using the STIMAN 3D software. The analysis made it possible to quantify the morphology of the hillock system on the substrate surface with respect to a number of parameters: the equivalent diameter, area, total area, and the shape factor both after Zn implantation and after annealing. Quantitative evaluation of the morphology of the system of surface hillocks will allow the nondestructive monitoring of the formation and evolution of nanoparticles in the subsurface layer of implanted samples during their heat treatment.

To describe the change in the structure of hydrothermal clay soils during the compression tests, a quantitative assessment of the pore space characteristics was carried out. A technique combining the data of scanning electron microscopy (SEM) and computer X-ray microtomography was used for the studies. The joint use of the results of image analysis obtained with the help of SEM and tomography makes it possible to quantify the distribution parameters of structural elements in the size range from fractions of a micron to several millimeters. As an object of research, hydrothermal clays were taken from the pit that was passed within the Vostochno-Pauzhetskoye geothermal field (south of Kamchatka Peninsula). All studied samples are characterized by high values of porosity and humidity. As a result of a quantitative analyses of microstructure it is revealed that in the investigated soils predominate small intermicroaggregate, intergranular, inter-microaggregate-granular micropores with equivalent diameter from 1 to 10 mkm. In this case, the presence of macropores with an equivalent diameter of more than 100 μm is of great importance, since the deformation of the sample occurs primarily due to macropores and small intermicroaggregate micropores. Analysis of the integral parameters of the microstructure (dispersion and anisotropy) were calculated from electron microscopic images obtained by a thousandfold magnification for specimens of the natural state and for specimens after compression tests. Patterns in the change of these parameters as a result of compression tests were not revealed. This fact is explained by the peculiarities of the formation conditions of the investigated soils — the inherited heterogeneities due to the pseudomorphic replacement of the structural elements of the initial volcanogenic rocks by clay minerals. The size, shape and orientation in the space of aggregates of clay particles are determined by the structure of the initial rock and directly by hydrothermal transformations.

A computer study of morphological characteristics using AFM images of a self-organized surface nanopore system in the structure of SiO2/Si(100) is performed. The nanopore system is obtained via Zn ion doping with subsequent thermal annealing. AFM images of the nanopore system are studied using the STIMAN 3D software. A correct quantitative estimate is made of the morphology of this nanopore system using a number of parameters (equivalent diameter, area, total area, and shape coefficient). Estimating the morphology of the self-organized surface nanopore system in the structure of SiO2/Si(100) allows us to narrow the possible practical applications of the resulting system in opto- and nanoelectronics.

Рассмотрен метод анализа структуры дисперсных грунтов комплексом растровый электронный микроскоп - рентгеновский компьютерный микротомограф (РЭМ - цКТ) и методика его реализации, основанная на возможности объединения результатов макро- и микроструктурных исследований в единый массив данных с помощью ПО “СТИМАН”. Опробование данной методики при исследовании многочисленной коллекции грунтов разного возраста, генезиса и степени литификации позволило, помимо микропор, выявить категорию макропор и оценить их вклад в общую пористость, что существенно повысило точность исследований структуры порового пространства глинистых грунтов.
