AB The article is aimed at studying the effect of temperature on structure of intermetallic phases of the protective zinc layer. The main objective of the article is a description of the structure and the changes that can occur during the heating process. The first part of the article deals with the description of the structure and mechanical properties of the interfacial phases and their arrangement. The main part of the article is aimed at study of brittle intermetallic phases, which arise due to increased temperature. For this reason, a set of samples of steel CSN 11 321 (DC01) was prepared. These samples were subjected to thermal heating in the tempering furnace. Subsequently metallographic cross sections were prepared, observed and assessed using SEM microscopy and EDS analysis. Also accelerated corrosion tests and pull off bend tests were performed. Conclusion of the article is trying to explain the influence of intermetallic phases on degradation of the protective layer.
