The Composition and Properties of Ruthenium-Iridium Coated Titanium Anodes

Material Composition and Coating Process

At the core of ruthenium-iridium coated titanium anodes lies a carefully engineered structure. The titanium substrate provides a robust foundation, chosen for its exceptional strength-to-weight ratio and inherent resistance to corrosion. The coating process involves the deposition of a mixed metal oxide layer containing ruthenium and iridium onto the titanium surface. This advanced coating technique ensures a uniform and adherent layer that maximizes the anode's performance.

The precise ratio of ruthenium to iridium in the coating can be tailored to meet specific application requirements. This flexibility allows for optimization of the anode's properties, such as catalytic activity, stability, and lifespan. The coating process typically employs thermal decomposition or electrodeposition methods, ensuring a strong bond between the oxide layer and the titanium substrate.
