Some experiments dealing with the isothermal hot dip galvanizing were carried out. The (Zn) – coating settled on the Armco-iron substrate were examined after arresting the solidification for different periods of time. The measurement of the thickness of each sub-layer in the coating were performed due to the SEM – analysis. The zinc segregation on the cross-section of the studied sub-layers were also determined by the EDS technique. The growth laws are formulated mathematically for each of the observed sub-layer. The mechanism of the sub-layer formation is also analysed due to the observation of the birth/nucleation of the phases in the sub-layers and the effect of flux onto the sub-layers morphology formation. The appearance of each phase is referred to the Fe-Zn diagram for stable equilibrium according to which these phases are the products of the adequate peritectic transformation.

Przeprowadzono eksperymenty izotermicznego cynkowania zanurzeniowego. Powłoka (Zn) osadzona na żelazie Armco poddana została badaniom po zatrzymaniu krystalizacji dla różnych czasów trwania cynkowania. Dokonano pomiarów grubości każdej z podwarstw powłoki dzięki analizie SEM. Segregacja cynku na przekroju badanych podwarstw również została określona dzięki pomiarom przy użyciu techniki EDS. Sformułowane są matematycznie prawa wzrostu dla każdej z analizowanych podwarstw. Analizowany jest również mechanizm kształtowania podwarstw dzięki obserwacjom narodzin/zarodkowania poszczególnych faz w podwarstwach oraz dzięki analizie oddziaływania topnika na morfologię podwarstw. Formowanie każdej z faz jest odniesione do diagramu równowagowego Fe-Zn zgodnie z którym fazy te są produktami odpowiednich reakcji perytektycznych.
