Abstract
Bath compositions for electrodeposition of Zn-Ni-Fe in chloride baths were studied_ Varying concentration of metal ions in the bath were used, at constant operating conditions, to obtain alloys containing 14 to 20 % nickel and up to 7.25% iron, It was found that the nickel content in the deposits not affected by addition of ferrous chloride from 0.02 to 0.08 M to the plating bath The codeposits without iron showed y phase structure with preferred crystal orientation (330) and (411). However, the crystal orientation of y phase changed to prefer (442) and (600) with iron codeposited in the Zn-Ni alloy. The microhardness of the deposits increases were observed, in these experiments, with increasing of iron content in the deposits. The highest hardness (535 VHN) found from the deposit obtained in the bath containing 0.5/0.4 Ni2-4-azi2+ molar ratio with addition 0.04 mol/l Fe2+.
