UDC 666.6 INFLUENCE fraction of oxygen in the plasma phase composition TiOh-coatings deposited by magnetron sputtering

The article presents the results of research carried out by X-ray diffraction in a coplanar mode at a fixed grazing angle of incidence of the crystal structure of thin coatings TiOx, obtained by magnetron method at different oxygen concentrations in the plasma and distances' magnetron-sample ". It obtained that with increasing concentration of oxygen plasma coating structure passes from the amorphous anatase-rutile through (with a predominance of anatase) to anatase, which is explained by an increase in input power to the growing coating. For each concentration of oxygen in the plasma at fixed points there is a critical process parameters layer thickness, which leads to excess crystallization. By increasing the distance 'magnetron-substrate "anatase peak intensity is growing, due to lower effect bombing coating plasma particles and increasing the energy extraction from the deposited particles with distance from the magnetron. It was determined that only for samples deposited at about 19.0. % O2 in the plasma is the maximum degree of crystallinity and the maximum share of the active plane, onto the poverhnost.Prichem this share does not depend on the distance "a magnetron-support", indicating that the specificity of a state of the magnetron plasma. Keywords: reactive magnetron sputtering, titanium oxide, anatase and rutile, X-ray diffraction.

UDC 666.3-183.2 Properties of clay modified by microwave radiation

In this work the adsorption of organic dyes to clay particles. The effect of microwave radiation on the adsorption capacity of clay particles. An increase of the monolayer adsorption capacity by modifying clays different mineralogical composition by microwave radiation. The dependences limit the dynamic shear stress on the concentration of organic dyes on the particles of natural and modified clays. It is found that as a result of exposure to microwave radiation from mobility data clay suspensions reduced. Keywords: clay, organic dyes, adsorption properties, microwave radiation, the mobility.
