摘要: 
Porcelain enamelled steel with various pretreatments was produced by a standard practice for evaluation of adherence using both conductivity measurement and periodic cracking method. From the test results, it was found that the adherence of porcelain enamel to steel treated with cobalt is higher than that treated with nickel and without transition metal. The difference in the adherence can be explained from an examination of the microstructure of enamel/steel interfaces by scanning electron microscopy. Good adherence is associated with those that have high density of anchor points at the enamel/steel interface. This suggests that the adherence of the porcelain enamel to steel is controlled by a mechanism of mechanical interlocking. In addition, a plot of the adherence index versus average shear stress shows a sigmoidal curve, within which the failure mode of the enamel changes from cohesive to adhesive at a critical load.
