A mathematical description for the (Zn) - coating formation with the presence of flux in the zinc bath is presented. This description includes the progressive vanishing of the products of the flux disintegration. A function which expresses the flux vanishing is formulated. The solidification of some phase sub-layers in the (Zn) - coating is considered with the use of a hypothetical pseudo-ternary phase diagram Fe-Zn-flux. Some relationships are formulated to define the varying Zn - solute redistribution as observed across the sub-layers. The relationships are based on the mass balance analyzed for the coating / bath / flux system. An amount of the growing phase in a given sub-layers is also defined mathematically.

Prezentowany jest matematyczny opis formownia powłoki cynkowej w obecności topnika w kąpieli. Opis ten uwzględnia stopniowy zanik produktów rozpadu topnika. Sformułowana została funkcja, która wyraża ten zanik. Rozważana jest krystalizacja faz w podwarstwach powłoki cynkowej z zastosowaniem hipotetycznego pseudo-potrójnego diagramu fazowego Fe - Zn - topnik. Sformułowane zostały równania celem zdefiniowania zmienności redystrybucji cynku obserwowanej na grubości poszczególnych podwarstw. Równania te bazują na bilansie masy analizowanym dla systemu powłoka / kąpiel / topnik. Zdefiniowana także została matematycznie ilość rosnącej fazy w danej podwarstwie.
