Popis: Phenomena related to an alternate means of preparing steel for discontinuous hot dip galvanizing using aluminum-containing galvanizing baths are presented in this paper, using electroless deposition of thin layers of Ni-P as a steel pretreatment before immersion in molten Zn-5 % Al alloy. By this means, the use of fluxes is eliminated. The greater chemical affinity of Ni to Al, compared with Fe and Zn, allows for control of the role of Al in the galvanizing reaction.
