— Adhesion/decohesion processes on the surface of dense metallic diffusion membranes in direct contact with hydrogen have been studied by scanning electron microscopy and energy dispersive X-ray spectroscopy. The elemental composition of the alloys has been determined to be (wt %) Pd 93 Y 7 , Pd 100 – х Pb х ( х = 5, 20), and Pd 94 Ru 6 . We have revealed Pb emission from the surface of the Pd 100 – х Pb х membranes and Pb adhesion to the surface of the Pd 93 Y 7 membranes. No adhesion of yttrium particles to the surface of the palladium–lead membranes has been detected. The surface of Pd 94 Ru 6 alloy has good stability to adhesion/decohesion processes.
