Enamel formation is: in the firing process of enamel products, enamel and metal surface complex between the physical and chemical reactions in the material through the wet glaze, diffusion, infiltration, and dissolved metals and other physical, chemical, purely mechanical reaction to form metal and enamel with different material properties, and this substance is found in between enamel and metal, so that a solid combination of metal and enamel.
Factors affect the formation of adhesion are: ①, enamel firing must have a certain time and must be carried out under a certain temperature; ②, the furnace atmosphere during firing must be carried out in oxidizing atmosphere; ③, when the end of glaze must have good capacity of the infiltration and dissolution of iron oxide glaze so that the expansion coefficient close to the end of the expansion coefficient of iron; ④, enamel adhesive agent containing a special time; ⑤, the end of the glaze in the firing must have enamel color change; ⑥, metal embryo surface roughness.
