Galvanealed coating evolution for hot forming steel

摘要：

　　The aim of the galvanealing experiments with three parameters of dew point,protective atmosphere and galvanealing time was to monitor the changes in coating quality and the evolution of coating after hot forming.The results show that,the three parameters have little effect on coating weight(thickness),and the average iron amount was within 9.51 to 14.9%.The ζ,δ and Γ phase for the as-received galvanealed samples transformed to Γ-Fe4Zn9and α-Fe(Zn)after reheating.The existence of a thin film of Γ-Fe4Zn9 increases the electrochemical potential to the base steel by a good amount and will not generate LME.
