Abstract

Carbon articles, particularly carbon electrodes, are protected against corrosive attack in use by fusing material to the article, or applying material to the carbon article which under the conditions of its use is capable of fusing to the carbon article, to form a coherent coating of protective material over only that part of the carbon article liable to corrosive attack when the article is in use.
