Abstract:

A geometrical model of glass-enamel coating (GEC) is proposed. Gas bubbles are chosen as the basic elements of its macrostructure, and the fundamental principles of the model are formulated. A model equation correlating the fraction of the open metal surface with the dissolution depth of enamel and GEC parameters is derived. Partial equations are derived according to various laws of the bubble size distribution such as invariance of the size, equal probability of any size, and normal, or lognormal distribution of bubbles over the size. It is shown that the open surface fraction always increases with the concentration of bubbles and contact angle, whereas its dependence on the GEC thickness and the statistical characteristics of the totality of bubbles has a more complex character.
