Влияние предварительной ионной обработки Zr сплава в среде водорода на структурно-фазовое состояние системы «Cr покрытие - Zr сплав»

Abstract

In the present study, we obtained Cr coatings on Zr substrates preliminary treated in argon-hydrogen medium using radio induced coupled plasma (ICP) source. This treatment is to additionally cleanse the substrate due to chemical reaction between Zr and H resulting in reduction of ZrO that exists on the surface to pure Zr. Magnetron sputtering (MS) method was used to deposit Cr coatings on Zr substrates preliminary treated for different times. Analysis of obtained samples was performed using X-ray diffraction, GDOES analysis and hydrogen analyzer RHEN602. After that there was carried out a series of experiments directed to find out the influence of above-mentioned treatment on adhesion of Cr coating to Zr substrate and oxidation resistance of Zr substrate with Cr coating
