Originální abstrakt

Mössbauer spectra of Fe-Zn intermetallic phases in real coating at steel were obtained. Results are comparable with values of laboratory samples of pure Fe-Zn phases. The most stabile phase of the system in temperature range 480 - 600 oC is delta phase. At 680oC pure gamma phase was obtained. It was confirmed that iron atoms diffusing into existing delta phase enter structure sites C. Effect of the technological parameters on IS negligible, QS increases with longer dipping time and higher annealing temperature and decreases with longer annealing time. On the surface of the coating oxidation takes place involving changes in Mössbauer parameters as well as existence of individual oxide phases containing Fe3+.
