METALLIC ELECTRODE COATED WITH CARBONACEOUS SUBSTANCE AND ITS PRODUCTION

摘要

PURPOSE:To obtain an electrode having characteristics of both of metallic and carbon electrodes by forming a coating layer of a carbonaceous substance contg. a prescribed percentage of graphite on a corrosion resistant metallic substrate. CONSTITUTION:A carbonaceous substance contg. 50-95wt% graphite is prepd. A corrosion resistant metallic substrate is coated with the carbonaceous substance by application or extrusion molding and the substance is dried and heated. Thus, a metallic electrode coated with a carbonaceous substance and having characteristics of both metallic and carbon electrodes is obtd.
