“…On the other hand, it has been known for a long time that Re can be electropated in aqueous solution that is compatible with other standard noble metal plating [18][19][20][21][22][23]. In this process the Re is deposited at the cathode in over-potential conditions, resulting in the concurrent production of hydrogen in the plating region.…”

We show that electroplated Re films in multilayers with noble metals such as Cu, Au, and Pd have an enhanced superconducting critical temperature relative to previous methods of preparing Re. The dc resistance and magnetic susceptibility indicate a critical temperature of approximately 6 K. Magnetic response as a function of field at 1.8 K demonstrates type-II superconductivity, with an upper critical field on the order of 2.5 T. Critical current densities greater than 10 7 A/m 2 were measured above liquid-helium temperature. Low-loss at radio frequency was obtained below the critical temperature for multilayers deposited onto resonators made with Cu traces on commercial circuit boards. These electroplated superconducting films can be integrated into a wide range of standard components for low-temperature electronics.

“…In contrast to the acidic citrate electrolyte, where rhenium, not cobalt, is predominantly reduced at the cathode 2,23 despite the low concentration of its ions in solution, the use of Cit–PPi electrolyte and varying the ligand ratio makes it possible to accurately select the coating composition within a wide range, and make it possible to solve a various specific technical problem. In general, the different ratio of refractory, hard and wear-resistant rhenium and ferromagnetic cobalt, in turn, gives a wide range of possible applications as a coating for hardening the surface of products, increasing the electrocatalytic activity of electrodes, or for imparting magnetic properties to the surface.…”

This paper presents a study of the electrodeposition of binary CoRe alloys from citrate and citrate-pyrophosphate electrolytes under the conditions of natural and forced convection caused by mechanical stirring and when a constant magnetic field (CMF) is applied. It is shown that a change in the complex composition of electrolytes makes it possible to radically change the chemical composition and properties of the obtained coatings: from an alloy deposited from a citrate solution and containing a significant amount of rhenium (up to 72.5 at. %) and which is nonmagnetic to coatings deposited from a citrate-pyrophosphate electrolyte containing 8–40 at. % rhenium and exhibiting magnetic properties. A model of the influence of CMF is proposed, which takes into account the convective flow not only in the direction along but also in the direction perpendicular to the electrode surface and the forces acting on the hydrogen bubbles, which are released during the alloy electrodeposition. The use of CMF makes it possible to improve the quality of electrolytic CoRe alloys and to obtain coatings close in their properties to those of hard magnetic materials.
