The paper deals with the problems encountered during the process of ga
lvanizing the parts and items made up of sinterized, porous and permea
ble materials. Since the porous materials, sinterized from metallic po
wders, are esentially defferent from the compact ones-their corrosion
protection has some particularities. We have laboratory-tested 4 types
of electrochemical galvanization, the best results being obtained wit
h a weakly acid galvanization electrolyte, having a law metal content
and using a pulsatory current; it was folio wed by a shiny galvanizati
on weakly acid based on chlorides, using high, current densities A dec
isive part was played by the galvanization surface preparation, e.g. t
he hot-and cold-water washings between the chemical and electrochemica
l steps.
