The electrodeposition and structure of Re-Pd alloy coatings is studied. The palladium content in the alloy is shown to be virtually proportional to its concentration in the electrolyte (at the constant concentration of rhenium-containing ions) and under the conditions studied reaches 29.3 at %. For the Pd content less than 7.6 at % only undistorted lines corresponding to nanocrystalline rhenium phase are revealed in X-ray diffraction patterns, whereas palladium lines are observed only at its content of 12 at % and higher. At Pd content of 16.9 at % and higher the Pd deposit contains both nanocrystalline and coarsely crystalline rhenium in addition to palladium and probably a small amount of an intermetallic phase with the Pd 0.88 Re 0.12 composition. The structural changes observed with the increase in the palladium content are associated with redistribution of deposit-absorbed hydrogen between the phases.
