Galvanizing of low-alloy high-strength steels / J.J. Sebisty and R.H. Palmer, Physical Metallurgy Division. : M38-8/43E-PDF

"Laboratory studies have been made on the galvanizing behaviour of several grades of low-alloy high-strength steel sheet in iron-saturated lead-containing zinc baths otherwise alloyed with chromium, manganese, nickel and vanadium. Beneficial modifications in coating formation and structure revealed were primarily related to suppression of the iron-zinc reaction rate. This was reflected in levelling out of iron-zinc alloy irregularities in coatings on normal activity steels and, at the opposite extreme, the characteristic linear attack of silicon-containing materials was drastically altered to a parabolic form. The bath addition of 0.1% V was found to be most effective and 0.2% Cr, 0.2% Ni and 0.5% Mn followed in that order. Within limits defined by the tests, use of such additions appears to offer improved control of the coating process in galvanizing of this class of steels"--Abstract, p. i.
