PRODUCTION OF ENAMELED SUBSTRATE

摘要

PURPOSE:To obtain an enameled substrate having high adhesion in simple stages by thermally spraying Ni or an Ni alloy on the surfaces of a metallic plate and forming an enamel layer on the resulting Ni or Ni alloy layer. CONSTITUTION:The surfaces of a metallic plate 1 such as a low carbon steel plate are degreased and roughened by blasting or other method. Ni or an Ni alloy such as Ni-Al is thermally sprayed on the roughened surfaces by plasma spraying or other method to form a thermally sprayed Ni or Ni alloy layer (intermediate layer) 2. An enamel layer 3 is then formed on the intermediate layer 2 as usual to obtain an enameled substrate. This enameled substrate is provided with high adhesion by an anchoring effect produced by thermal spraying.
