[en] The influence of annealing atmosphere oxidation potential on the surface condition of an industrial dual-phase steel alloyed with 2 wt% Mn and 0.3 wt% mo has been studied by galvanizing simulation, with particular attention towards alloying element segregation, the occurrence of selective oxidation of the surfaces immediately prior to hot-dip galvanizing and their effect on reactive wetting and coating adherence. The surface chemistry and morphology prior to dipping have been analyzed in detail, along with their evolution during annealing, and the coating quality and chemistry were characterized and interpreted in relation to the surface condition prior to dipping.
