Work was performed in four areas of process improvement studies 1 anodizing and re-forming 2 pyrolytic conversion 3 carbon and silver coating and 4 screening and dielectric absorption. The major results of the studies show that 1 new anodizing racks and anodizing cathodes have provided high product uniformity at anodizing and improved electrical characteristics over previous anodizing conditions 2 conditions of flow and of heat exchange of the conversion atmosphere, and conversion times, have been optimized, base d upon the magnitudes of the final re-forming currents and 3 the best electrical results, based upon comparative studies, have been obtained with three carbon coats applied to the anodes and extended carbon and silver coating curing cycles.
