“…The relevant studies are focused on the percentage of certain elements, for example aluminium, nickel and lead. The reports allow a deeper study of a zinc alloy character [6][7][8]. The relevant research was rather focused on basic evaluation and the applied methods potential will be extended gradually.…”

“…The basic evaluation by metallography was realized, in particular, because this method can be compared very well to the computed tomography (CT). The research [7] presented the influence of bismuth and tin, which were added into a Zn-AlNi bath, on microstructure and corrosion resistance of hot dipped galvanized plating. The study output provided an ascertainment that compared to the Zn-AlNi plating, the Zn-AlNiBiSn plating features lower corrosion resistance.…”

The technology of high-pressure die casting thin-walled castings requires increased demands on the stability of technological processes and pressure casting parameters. The wall thickness of the studied zinc alloy castings (ZP0410) ranges from 0.4 to 1.2 mm. In general, it is necessary to use higher mould operating temperatures and a higher casting speed when filling the mould cavity when casting thin-walled castings. There is an increased load on the mould (tool) and the die casting machine during this casting process and the use of more demanding parameters. It results in a shortening of mould service life. There is currently no own returnable material (alloy ZP0410) used in the given production conditions in the production of thin-walled castings. Only the primary alloy ZL0410 is used now. It must be emphasized that the ability to implement the recycling of these returnable materials is becoming increasingly important. However, it is necessary to ensure that the quality of production is not reduced. The research was carried out aimed at determining the current state. Methods of roughness analysis, computed tomography, and metallography of casting defects from casting machine failures even after plating are used in the study of existing production technology in addition to standard long-term monitoring of melt quality. The findings of these research activities were briefly summarized in the paper. The experimental development of the technology of using our own returnable material in this quality-intensive production is in progress now.

“…However, the increasingly higher requirements for the corrosion resistance of steel products mean that the zinc coating often does not meet these expectations. Additionally, the widespread use of Pb [ 4 ], Bi [ 5 ] and Sn [ 6 ] alloying additions may lead to a reduction in their corrosion resistance [ 7 ]. Therefore, new zinc baths based on Zn-Al-Mg alloys for hot dip galvanizing have been developed.…”

The article presents the results of studies on the influence of Mg on the formation of the periodic layered structure of the Zn-AlMg coatings. These coatings were produced by the double batch hot dip method in a Zn bath and then in a Zn-Al(Mg) bath with a content of 15, 23, 31 wt.% Al and 3, 6 wt.% Mg. The microstructure of the coatings (OM, SEM) was revealed and the phase composition (XRD) obtained in two-component Zn-Al baths and Zn-AlMg baths were determined. The periodic layered structure was found to consist of alternating FeAl3 phase layers and a bath alloy (Zn + Al + Mg). Moreover, it was observed that the addition of 3 wt.% Mg reduces the thickness of the coating in baths containing 23 and 31 wt.% Al. However, the addition of 6 wt.% Mg causes complete disappearance of periodic layered structure in a bath with 23 wt.% Al. In a bath with a content of 31 wt.% Al the addition of 6 wt.% Mg creates a compact layer consisting of the FeAl3 phase containing the precipitation of the MgZn2 phase and Fe2Al5 phase. Such a structure of the coating transition layer limits the growth of the periodic layered structure in the coating.
