HOT-DIP GALVANIZING BATH AND PROCESS

摘要

The zinc bath, which is particularly useful for batch-wise galvanizing steel articles, contains 3-15 wt.% of tin, lead at a concentration up to saturation and 0-0.06 wt.% of at least one of aluminium, calcium and magnesium, the rest being zinc and unavoidable impurities in order to diminish the influence of the silicon content of the steel to be galvanized on the coating thickness.
