“…The Raman spectra shown in Figs. 6. a. and b. let appear a doublet at 1400 cm -1 which is characteristic of the presence of α-Al 2 O 3 [31,32] but no signal was observed in the Raman domain ( Fig. 6.…”

B2-FeAl-based aluminide coatings were elaborated on P92 ferritic-martensitic steels by slurry. Under atmospheric pressure of steal and 650°C, a thin protective α-Al 2 O 3 oxide layer formed and was maintained until 5000 h. With increasing pressure to 300 bar, the morphology of α-Al 2 O 3 changed markedly. Iron oxide clusters started to appear at the surface of the scale after 5000 h of exposure and kept on growing till 10000 h. It appears that pressure increased the outward diffusion of Fe through the coating and through the oxide scale and fostered the propagation of the tensile cracks of the coating.

“…These refractory elements have outwardly diffused from the interdiffusion a b 15.9 s (Fig. 5b), where the two vibrations 650 and 890 cm −1 were associated with NiAl 2 O 4 [23]. The partial incorporation of Cr into the NiAl 2 O 4 structure could explain the Raman shifts observed between the curves.…”

“…The results showed that high applied current density lead to formation of crack network on the microstructure of the coatings. The development of the crack network was attributed to the rising of internal stresses caused by rapid deposition kinetics [32]. Increased current densities enhance the deposition kinetics and promote rapid codeposition, which forms coatings that exhibit no improved properties.…”

Deterioration of metals and alloys during service due to corrosion and wear phenomena shortens materials life span and structural integrity particularly in aggressive environments such as coastal and marine. This degradation also limits the use of these materials in most industrial applications. Therefore, the improvement of the quality of these materials in order to combat these challenges in industry remains critical. Surface modification techniques are employed to enhance materials properties to enable better performance and to extend their applications in demanding environments. Electrodeposition has been a useful method developed to improve the corrosion and mechanical properties of materials. In the present contribution, ample knowledge about electrodeposition of Zn composite/nanocomposite coatings and their characteristics are reviewed to address coastal and marine degradation of metals and alloys.
