Effect of Surface Texture of Steel Sheets on the Crystal Orientation Relationship between Zinc and Iron on Electrogalvanized Steel Sheets

To elucidate the effects of polyethylene glycol PEG and glue on the deposition behavior of Zn from electrowinning solutions and its crystal structure, Zn electrodeposition was performed at a current density of 600 A•m −2 and a charge of 8.64 × 10 6 C•m −2 in an agitated sulfate solution containing 1.07 mol•dm −3 and 1.8 mol•dm −3 of ZnSO 4 and H 2 SO 4 , respectively, at a temperature of 45. With the additions of PEG and glue, the evolution of hydrogen was suppressed at current density region less than the critical current density for Zn deposition, resulting in decrease in critical current density of Zn. The degree of decrease in critical current density of Zn was larger with glue than that with PEG. The current ef ciency for Zn deposition was higher with PEG and glue than that without at low current density region because the critical current density of Zn decreased with additives. Since the additives suppressed Zn deposition more than the hydrogen evolution at high current density region, the current ef ciency of Zn decreased with increasing concentration of additives in solution. At high current density region, there was little difference in current ef ciency of Zn between PEG and glue. The effect of molecular weight of PEG on the current ef ciency of Zn was rarely observed at molecular weight above 2000. With an addition of PEG, the deposits became ne platelets crystals with preferred orientation of {1011} and layered pyramidally, while the deposits orientated to {1120} preferentially and the platelets crystals grew perpendicularly to the substrate with an addition of glue. The surface roughness of deposited Zn decreased with additives and it was smaller with PEG than that with glue.

To elucidate the effects of polyethylene glycol (PEG) and glue on the deposition of Zn from electrowinning solution and its resulting crystal structure, Zn electrodeposition was performed at a current density of 600 A•m ¹2 and a charge of 8.64 © 10 6 C•m ¹2 in an agitated sulfate solution containing 1.07 and 1.8 mol•dm ¹3 of ZnSO 4 and H 2 SO 4 , respectively, at 45°C. With the additions of PEG and glue, the evolution of hydrogen was suppressed at the current density region less than the critical current density for Zn deposition, decreasing the critical current density of Zn. The degree of decrease in the critical current density of Zn was larger with glue than that with PEG. The current efficiency for Zn deposition was higher with PEG and glue than that without at the low current density region because the critical current density of Zn decreased with additives. Since the additives suppressed Zn deposition more than the hydrogen evolution at the high current density region, the current efficiency of Zn decreased by increasing the additive concentration. At the high current density region, little difference was observed in the current efficiency of Zn between PEG and glue. The effect of the molecular weight of PEG on the current efficiency of Zn was rarely observed at the molecular weight above 2000. With the addition of PEG, the deposits became fine platelets with preferred orientation of f10 11g and layered pyramidally, while f11 20g orientation was obtained, and the platelets grew perpendicularly to the substrate with the addition of glue. The surface roughness of deposited Zn decreased with additives, and it decreased further with PEG compared with that with glue.
