... of the specimen and coated edge). Coatings are usually very thin, and they can be softer (zinc) or harder (enamel) than the steel base. Methods to preserve a flat edge are discussed in this article. Also, metallic coatings on steel, for example, zinc-base coatings, form an electrolytic cell in the presence...
