Features of microstructure of promising Pd-Ru alloy

The paper shows features of microstructure of palladium-based membrane alloy, which alloyed with ruthenium content of 6 wt.%. The alloy with such ruthenium content has good strength and hydrogen permeability. Samples for the study are made of metals of high purity (99.9%) and are presented in the work in the form of a membrane-foil with a thickness of 30 mkm and a tube with an outer diameter of 0.9 mm and an inner diameter of 0.1 mm. The study of microstructure features of the samples was carried out in the work by methods: X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDRS), and scanning electron microscopy (SEM). X-ray diffraction method established formation of solid substitution solutions with substructure of high degree of homogeneity and nanodispersity. EDRS and SEM methods tested the elemental composition of the samples and their surface morphology. SEM images of the samples’ surface confirmed the high homogeneity and nanodispersity established by X-ray diffraction.
