Characterizations of intermetallic layers, e.g., thickness, species and cross-sectional microstructures were performed. Growth kinetics of the intermetallic layer was analyzed by diffusion theory and the Arrhenius equation. It was found that an aluminium and iron aluminide layer, Fe2Al5 phase, were mainly detected for all investigated hot-dip aluminizing processes. The thickness of the iron aluminide layer increased with increasing temperature and time, according to the diffusion theory. The activation energy of 86.51 kJ/mol was determined. Finally, a simulation diagram of the predicted layer thickness as a function of aluminizing temperature and time was constructed. Moreover, to observe and illustrate the phase transformation of the iron aluminide layer, the selected hot-dip aluminized condition was annealed at a temperature of 800 °C for 12 h. 2020-05-20T04:41:48Z 2020-05-20T04:41:48Z 2020 Chiang Mai Journal of Science 47,2 (March 2020), p.319 - 328 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=10706 http://cmuir.cmu.ac.th/jspui/handle/6653943832/68610 Eng Faculty of Science, Chiang Mai University
