The effect of the additives on the Zn-Ni alloy electrocrystallization from a chloride bath was investigated by means of electrochemical methodes, scanning electron microscopy and measurement of surface appearancd, X-ray diffraction patterns. The additives thestd ware the Saccharin, surfactant of naptalene-derivative and mixed additive, The resistance of electrodeposit increased by adding the additives, whera the effect of additives on resistance was different with current density roughness, apperarance and morphology of deposit were also influenced by the type of additive. The deposir with fine, compact grains as well as good surface roughness and appearance was obtained from the mixed-additive added bath.
