Abstract
A triple-point cathode coating and method wherein electrically conductive NEA diamond particles cast or mixed with the adhesive medium and electrically insulative NEA diamond particles are cast or mixed with the adhesive medium to form a plurality of exposed junctions between electrically conductive diamond particles and electrically insulative diamond particles to reduce any electrical charges on a structure coated with the coating.
