ABSTRACT:
The minute pores and discontinuities which are normally present in protective oxide coatings on carbon bodies can be closed and, if desired, filled by immersing the coated carbon body in a metal salt melt having a boiling point above 400.degree. C., and electrodepositing the melt on the coated carbon body. When the electrodeposition step is continued sufficiently long to fill the pores, the product when cool is a coated carbon body carrying an oxidation agent-resistant coating which is keyed into the surface of the carbon.
