ANODE FOR OXYGEN EVOLUTION AND RELEVANT SUBSTRATE

摘要

THE INVENTION CONCERNS AN ANODE FOR GAS EVOLITION IN ELECTROCHEMICAL APPLICATIONS COMPRISING A TITANIUM OR OTHER VALVE METAL SUBSTRATE CHARACTERIZED BY A SURFACE WITH A LOW AVERAGE ROUGHNESS, HAVING A PROFILE TYPICAL OF A LOCALIZED ATTACK ON THE CRYSTAL GRAIN BOUNDARY. THE INVENTION FURTHER DESCRIBES A METHOD FOR PREPARING THE ANODIC SUBSTRATE OF THE INVENTION COMPRISING A CONTROLLED IN A SULPHURIC ACID SOLUTION.
