Abstract

Pulse plating Zn-Fe (6.0 wt%-7.4 wt%) deposits have been studied by means of X-ray diffraction. The results showed that pulse current parameters affected not only the textures of the deposits but also their phase constitutions. Under the condition of average current density of 6A/dm(2) in pulse plating, when pulse frequency was larger than or equal to 100 Hz, the Zn-Fe deposits were identified as h.c.p. eta-phase; if pulse frequency was less than or equal to 1 Hz, the Zn-Fe deposits were of eta- and monoclinic zeta-phases. At constant average current density and pulse frequency, an increase of the duty cycle results in an increase of the (101) texture coefficient of the Zn-Fe deposits, while the decrease of the duty cycle favoured the formation of a deposit with (112) texture. A Zn-Fe deposit with (112) highly preferred orientation was obtained.
