Abstract

In this paper,the effects of additives,complex agents and current densities on thetexture and grain size of the zinc deposits from zincate baths are studied by means of X raydiffraction. The results show that the existence of additive AA-1 causes the preferential orientationof(101) face;when DIE is added alone,the preferential orientation changes to(110) face;withadditives both DIE and AA-1,Zn deposits with highly preferential orientation of(110) are obtainedin a certain range of current densities,and if complex agents TEA and EDTA are simultaneouslyexisted ,fine granular and bright Zn deposits with highly preferential orientation can be obtained in thewider range of current densities.
