In this paper using methods of transmission electron microscopy, electron dif-fraction and vibrating sample magnetometry techniques the films of Pd, Ni, and a Ni–Pd alloy, deposited by pulsed laser ablation as one-element, so as composite two-element targets of Ni–Pd, have been investigated. It was established, that at alternate deposition of laser erosion plasma of Ni–Pd, films with metastable hexagonal (hcp) crystal lattice can be formed. Crystallographic parameters of this lattice are growth monotonically with increasing of content of Pd. After annealing these films acquire an equilibrium cubic (bcc) structure and transforms to ferromagnetic state. The de-pendence of the solid solution lattice constant of Ni-Pd alloy on the concentration of Pd exhibits a positive deviation from the Vegards law.

Found that differences in the structure of the dispersed gel component of the stone on HBV with a complex chemical additives and without it were found. With the help of computers have been calculated characteristics of the dispersed submicroscopic structure of the gel component. The average size of the gel pores of 350 Å. The use of composites in gypsum containing finely ground waste MMC contributes to a significant increase in the packing density of particles due to the uniform arrangement of fine grains between larger, increase in composite strength and enhance their water resistance.

The process was studied of an erosion of titanium nitride coatings deposited on stainless steel (SS) substrates using two different vacuum-arc technological ways: with high voltage negative pulses on substrate and without of the ones. The erosion rates were measured with weight loss method by sample weighting before and after exposure in the stationary plasma of magnetron type discharges. The typical discharge parameters were: ion current values were 40-180 mA, cathode potential values were 400-1000V, magnetic field was 0.05T, work gas pressure was about 0.2 Pa. With help of Longmuir probe the edge plasma characteristics were measured, such as electron temperature and electron density.

A new method of gas-jet deposition of metal-polymer composites with simultaneous deposition of polymer matrices and silver clusters from two gas-dynamic sources is described.
Polytetrafluoroethylene (PTFE) is chosen as a matrix material owing to its high stability to thermal and chemical effects and to biological compatibility. Precursor PTFE is Hexafluoropropanone (C3F6O). Implementation of the method required creation of two high-temperature sources: for formation of a high-temperature flow C3F6O and for evaporation of silver in the argon environment. Typical mass flows of C3F6O and argon are approximately 0.1 g/sec; the mass flow of silver vapors in the argon flow is approximately 10−4 g/sec.
Specific features of cluster deposition and the properties of composite films are described. Results on the antibacterial effect of silver-polymer composites on stock cultures of various bacteria are reported.

В данной работе проведено исследование влияния некоторых условий осаждения на скорость роста и морфологию алмазных кристаллитов на начальных стадиях роста алмазного покрытия (АП). Химическое газофазное осаждение АП на молибденовые и вольфрамовые подложки проводилось с помощью CVD – реактора с СВЧ газовым разрядом в среде метан – водород. Содержание метана (CH4) в газовой смеси изменялось от 1% до 2% при давлении от 150 до 230 Торр и температурах подложки в диапазоне 750… 960ºC. Показано что, в диапазоне температур подложки 800-960оС скорость осаждения и плотность зародышеобразования АП сильно зависит от температуры подложки и имеет экстремальный характер.

In this contribution the physical reasons have been analyzed and the thermodynamic substantiations lying at the basis of existence of dependence of potential energy of atomic interaction on the size of a nanosystem are given. Due to the molecular static studies and the Morse potential we simulate the solid nanofilms of monatomic metallic systems with fcc structures. Such size-induced characteristics of films as optimal thickness, lattice parameter, effective pair potential, energy density of the system are computed. The dependence of pair potentials of atomic interactions on the size of a nanosystem is substantiated and the corresponding methodology of phase diagram construction of binary thin nanofilms Bi-Sn is offered.

As a result of high-temperature oxidizing of silicon, and also of some additional reasons, in near-surface layers the complex defect region which consists of disordered silicon and a layer containing dislocation networks is formed. The depth of this defective layer is spread from the interface into the silicon to 20-30 microns. The given defect structure is formed owing to excess of mechanical stresses magnitudes of a threshold of plasticity
