New Composite Boron Doped Diamond Coatings for Electrochemcial Oxidation

This project will result in new, composite boron doped diamond (BDD) coatings for inexpensive metal substrates that will provide superior electrodes with improved water purification properties as well as excellent adherence and corrosion-resistance. Eltron’s composite BDD coatings contain no organic binders or materials that will be susceptible to attack by the extremely powerful reactive oxygen species (ROS) generated by a salt-free electrochemical (EC) oxidation. The coatings cure at low temperatures, eliminating the coefficient of thermal expansion (CTE) mismatch problems seen between other BDD coatings and substrates. In other applications, the coatings have shown conductivity that can be precisely tuned for specific applications. In addition, the coatings have been shown to be extremely adherent to metal, ceramic, and plastic substrates, providing good contact and a rugged electrode. The use of BDD coated electrodes will enable a salt-free EC oxidation process that reduces consumables and improves stability and ruggedness. The BDD coatings will allow sturdy electrodes and easy electrical connection to the EC system in a rugged way, suitable for military field use.
