Abstract: Hot-dip coated steel articles having a coating containing about 55% aluminum, 43% zinc, 2% silicon, are known to exhibit an optimum combination of general corrosion resistance, more durable than zinc coatings; while providing more galvanic protection to cut edges and areas of mechanical damage than hot-dip aluminum coatings. It has now been found that coatings containing 12 to 24% zinc, up to 4% silicon, balance aluminum, provide galvanic protection equal to or superior to such known coatings, while providing enhanced general corrosion resistance, approaching that of aluminum coatings.

Abstract: To recover the zinc from zinc-coated objects, said objects are anodically stripped by applying a voltage of 2 to 9 V in dilute sulphuric acid and the zinc is then electrolytically recovered from the ZnSO4-containing solution after removing the iron which may possibly have been dissolved. During the stripping operation, the current level is monitored at the same time and the voltage source is switched off when a change in the current level corresponding to the stripping of iron occurs. The iron which may have dissolved can be oxidatively precipitated as oxide or hydrated oxide by, for example, feeding in compressed air after adjusting the pH to 3 to 5 with calcium carbonate and filtered off. The apparatus for carrying out the method comprises an electrolysis cell (1) in which the zinc is stripped, a reaction vessel (6) for removing iron and an electrolysis cell (12) for recovering the zinc from the solution. <IMAGE>
