What is galvanization •galvanization is coating a metal with a layer of zinc as a protective coating •the zinc layer in a galvanized steel will protect. By browsing materials today, you agree to our use of the challenge of thickness variation in plating and these processes include electroplating of zinc. Lab: determining the thickness of galvanizing purpose: determine the thickness of the zinc coating on galvanized iron or stainless steel background: galvanized iron consists of an iron core sandwiched between two very thin layers of zinc metal. V= 034 g / (713 g/cm3) = 0047 cm3 to calculate the thickness of the coating: the volume a rectangular solid should be given by v = area x thickness rearranging mathematically, one obtains: thickness = v / area using our results from above to substitute: thickness = 0048 cm3 / 963 cm2 = 00050 cm this is the total thickness. Purpose: in this experiment, you will determine the thickness of zinc on a piece of galvanized steel gravimetrically overview: relying on the differences in activity between zinc (the galvanizing coating) and the coated steel, the zinc will selectively be removed using hydrochloric acid and the mass of the zinc coating determined.
