Protective and Decorative Vacuum’s Coatings on Wares of Artistic Castings

The problem of environmental protection is extraordinarily important, and its actuality will increase with every year. In this aspect, processes of depositing of coatings in vacuum have got serious advantages before wide-spread galvanic method, as the last requires building of the special cleansing building, which cost in general balance of covering’s process can arrive till 60 %. It should be noted that preliminary preparation of surface which, as is generally known, has the important value at the method of metallization in vacuum often execute by the smoldering discharge (by the «dry method»)

The Modern State of Works in Field of Electron-Beam Technology of Melting and Evaporation of Metals and Non-Metals in a Vacuum

In developing of new processes for growing metal (composite) films, the main attention is given to controlling the metal vapour flows: through energy state of the condensing particles, their molecular composition, intensity, spatial distribution of the flow, etc. It is known that the widely accepted open-type evaporators, including quasi-closed ones, are characterized by instability of the directivity diagram of the vapour flow in time, even at constant temperature. Radiation load on the film growth surface from these sources is sometimes comparable to the energy of vapour flow condensation. Therefore, when they are used, it is quite difficult to produce reproducible film structures with controllable parameters. Particular difficulties arise at high evaporation rates, when micro-drops are usually present in the vapour flow

Production Technology, Physical, Mechanical and Performance Characteristics of Cu-Zr-Y-Mo Finely-Dispersed Microlayer Composite Materials

The production of Cu-Zr-Y-Mo Finely-Dispersed (FD) microlayer composite materials for electrical contacts by the method of electron-beam evaporation and layer-by-layer condensation from the vapor phase is described and the chemical composition, structure, density, electrical conductivity, hardness, and main mechanical characteristics of the materials in the temperature range from 290 to 1070 K are studie

On the Corrosion Resistance of Cu – Mo Composite Materials obtained by PVD Method

The Cu – Mo composite materials have been obtained by electron flow vaporizing followed by vapor –phase condensing. Researches have shown that corrosion resistance in wet environment varies with the content of molybdenum, working conditions and composition of the corrosion medium. The corrosion resistance of the composites has been studied by gravimetric method
