Abstract
The structure and composition of deposited Ir–Ru alloys is studied as a function of the electrolysis conditions. It is found that the maximum temperature at which continuous layers of Ir–Ru deposits can be obtained increases relative to pure components. The continuous layers form as solid solutions throughout the entire range of compositions (from 0 to 100% of either component). An anomalous predominant deposition of the more negative component (ruthenium) into the alloy is discovered. Several types of the alloy structure are found: columnar, spherulitic, layered, and spiral. Conditions leading to the deposition of layered structures are analyzed.
