Abstract (technical / expert description):


The durability of diamond titanium electrodes is limited especially due to the anodic load of the electrochemical dissociation of the titanium carbide interface between diamond and titanium substrate. With the use of tantalum or niobium as more stable electrode material, the lifetime of diamond electrodes can be increased significantly. A new research effort aims to develop economic diamond electrodes, for which firstly a tantalum or titanium intermediate layer is deposited on titanium or steel plates. After this, the boron doped diamond coating will be deposited.
