Ion plating can be done in a plasma environment where ions for bombardment are extracted from the plasma or it may be done in a vacuum environment where ions for bombardment are formed in a separate ‘ion gun’ as shown in Figure b. The configuration shown in Figure (b) is often called ion beam assisted deposition (IBAD) or ion beam enhanced deposition (IBED).

Figure 4(a) shows that the corrosion products of Zn-5Al coating are smooth and loose, and there are some holes on the surface, so the corrosion products cannot prevent the corrosion media from penetrating by: 5. The corrosion products were analyzed by XRD. The surface and section microstructures were observed by SEM.
The results showed, the corrosion resistance of 4 kinds of Zn-Al-Mg coated steel is 4 times as galvanized steel. The Zn-Al-Mg coated steel sheets can be self-cured. MgZn 2 and eutectic could be found in all ZAM by: 1.
Zn–Al–Mg alloy (ZM) coating provides a decisively enhanced corrosion resistance in a salt spray test according to DIN EN ISO (NSS) compared to conventional hot-dip galvanised zinc (Z) coating because of its ability to form a very stable, well adherent protecting layer of zinc aluminium carbonate hydroxide, Zn 6 Al 2 (CO 3)(OH) 16 4H 2 O on the steel by: Steel sheet coated with zinc or 55%Al-Zn is widely used at the civil construction, mainly for roofing and cladding applications.
The 55%Al-Zn coated steel shows mechanical properties slightly different from zinc coated steel, even under the same heat cycle processing, due to the higher molten metal temperature and also to the higher strength of.

Summary. Acknowledgement. Tanaka et al. 3 investigated the corrosion behavior of a zinc alloy coating consisting of 11 wt.% Al, 3 wt.% Mg and wt.% Si. They attribute the enhanced corrosion resistance of this coating system to a corrosion product layer consisting of basic zinc chloride, ZnCl2 4 Zn(OH)2, which is able to suppress the oxygen : Susanne Schürz, Martin Fleischanderl, Gregor Mori, Karl-Heinz Stellnberger, Gerald H.

The AlCrN and AlCrON coatings were deposited on plasma nitrided H13 steels through ion-source-enhanced arc ion plating, and their structures, mechanical properties, thermal stabilities, and tribological properties were investigated. Structural analysis showed that the monolayer AlCrN and AlCrON bilayered coatings were mainly composed of fcc-AlCrN and fcc-AlCrON solid solution phases respectively.

The type II hot corrosion behavior of NiCr20 model alloys with the additional alloying elements, iron and cobalt, is investigated at °C in synthetic air + % SO 2 with two different salt deposits. For the cobalt‐containing alloy, an increased metal loss is observed, whereas the iron additions decrease the corrosion attack.
