The presence of alloying elements in the galvanizing bath has been shown to affect the properties of the zinc coatings during the galvanizing process [1, 2]. However, only a few studies have examined the use of copper in the process of galvanizing [3].

Two patents reported on an adhesive coating comprising a ternary alloy (55–75 wt% Cu, 15–45 wt% Zn and 0.1–10 wt% Fe) that is useful for coating steel wire. The chemical nature of the alloys elaborated by sequential electroplating and heating of copper, iron and zinc layers avoids a separation between the coating and steel wires during wire drawing [4, 5].

In the present study, the emphasis is placed on the Zn-rich corner of Fe–Zn–Cu ternary system, which, up to date, remains unknown.

Before galvanizing, two low-carbon steel substrates were classically prepared [ 6]. The first substrate was rolled with copper wire. A copper piece was hammered in the middle of the second one to make a rivet (Fig.  1). As-prepared samples were then batch...
