Abstract The electrodeposition of zirconium has been studied in molten Flinak electrolyte containing zirconium fluoride.A coherent,dense deposit of zirconium has been obtained.It is shown that there are two differ- ent mechanisms for electrodeposition of zirconium,i.e.,metalliding and electroplating,which depend on the electrode material used.X-ray diffraction analysis indicates that the microstructure in the zirconium deposit appears as a texture oriented preferably along Zr[110].A lustrous coating of zirconium with a surprisingly smooth surface may be deposited on copper substrate under appropriate conditions.The de- posit is identified by TEM as an amorphous alloy of Zr and Cu.
