Summary

The role of the nickel-flash coating conventionally used to promote adhesion between steel and porcelain enamel was investigated. The surface morphology of nickel-flashed steel developed under the controlled atmosphere at the firing temperature corresponds to that of an aggregate structure observed in an NiO-Fe displacement reaction couple. This unique structure provides chemical bonding to the porcelain enamel coating and metallic bonding to the steel substrate.
