Electron-beam surface treatment of alloys based on titanium, modified by plasma from an electrical explosion of conducting material

We present the results from investigating the phase composition, structure, and properties of surface layers of titanium alloys subjected to combined treatment that includes plasma alloying the electric explosion of a carbon fiber with a quantity of TiB₂ powder and subsequent irradiation with a high-intensity electron beam. The formation of a multilayer, multiphase structure in the submicro- and nano-sized ranges is observed. It is shown that the properties of a alloyed layer exceed those of a bulk sample many times over.

Electrochemical ultramicromethods of analysis

Summary Electroanalytical methods have been used under the conditions of chemical experimentation on the ultramicroscale. Capillary cells for coulometric titration with detection of equivalence points by various methods are described. A design is suggested for a reference palladium-hydrogen microelectrode with its own gas supply and a technique is described for measuring p_H by the quinhydrone method with the use of an insignificant fraction of the small test volume of solution. Coulometric ultramicrodeterminations based on oxidation-reduction, precipitation and complex formation have been carried out. By the suggested experimental technique, Zn, In and Ni have been determined in small samples of semiconductor alloys and cosmic particles.

Zusammenfassung Elektrochemische Analysenmothoden wurden, im Ultramikromaßstab angewendet. Kapillarzellen für coulometrische Titrationen mit verschiedenen Methoden der Endpunktanzeige wurden beschrieben. Eine Palladium-Wasserstoff-Bezugselektrode mit eigener Gasversorgung wurde angegeben und ein Verfahren beschrieben, um p_H-Bestimmungen nach der Chinhydronmethode in einem ganz kleinen Teil einer Probelösung auszuführen. Coulometrische Ultramikrobestimmungen auf der Grundlage von Redoxvorgängen, von Fällungsreaktionen und von Komplexbildungen wurden ausgearbeitet. Mit Hilfe der empfohlenen Arbeitsweise wurden Zn, In und Ni in kleinen Proben von Halbleiterlegierungen und kosmischen Partikeln bestimmt.
