The meniscograph and the sessile drop wetting methods, associated
with in situ surface analyses, were used to quantify the influence
of the annealing atmosphere on zinc wetting during the hot dip
galvanising of high strength steels. If a clear wetting improvement is
obtained for higher oxygen partial pressures, associated with a sufficient
hydrogen amount, in the soaking area, a dry atmosphere
above the zinc bath has however to be preferred.
