“…The size of these oxide crystals ranged 4-15 μm. This morphology was consistent with that of the chromium oxide film typically observed in iron-based alloys with high chromium content at a high temperature [28,29]. The crosssection morphology (Figure 5c) showed that the oxide layer formed by the polygonal flake crystals was not dense.…”

A novel glass-ceramic coating was applied onto the 1Cr11Ni2W2MoV stainless steel. The oxidation and corrosion behaviors of coated and uncoated steels were comparatively investigated in air and in the presence of NaCl + Na2SO4 eutectic deposits at 650 °C, respectively. Protective scales formed on the surface of stainless steel prevented the severe oxidation of the alloy. Catastrophic hot corrosion occurred on the steel when a salt film was attached, producing loose iron oxide layers and internal corrosion zone. The glass-ceramic coating acted as a barrier that effectively hindered the invasion of corrosive species during the oxidation and hot corrosion tests.

“…Comparing the formation of a thin alumina layer for the aluminized coatings during hightemperature oxidation with a chromia scale formation occurring at this process for uncoated Cr-rich stainless steels, the former can be considered as preferable. It may be related to significantly slower formation of the aluminum oxide scale, according to a number of studies conducted with stainless steels with sufficient contents of Al in the their compositions, and to a better adhesion of this scale to the steel substrates (Ref [39][40][41] and, hence, to significantly reduced breakaway. The mentioned point indicated for steels can be also applied for the aluminized coatings.…”

The aim of the study was to obtain a preliminary data focused on the steam oxidation performance of multilayered coatings deposited on 310 stainless steel and 800H Incoloy. The coatings were obtained through the aluminizing thermal diffusion technology with the formation of aluminides; some coating options had an additional top layer of selected composition. In this study, five different coating systems, as well as uncoated metals, were exposed at 1000°C using thermogravimetric analysis instrumentation simulating an initial stage of steam oxidation corrosion. In this work, along with determination of the mass change of the samples, microanalyses using light optical microscopy, scanning electron microscopy (SEM) equipped with energy x-ray dispersive spectrometry (EDS), as well as surface micro-hardness determination, have been carried out. The designed coating systems demonstrated promising high-temperature steam oxidation performance with no breakaway degradation issues.

“…have proved that alumina volatility by Al(OH) 3 formation is not expected to be an issue below 1300 °C for long-term applications [12]. However, the ductility of alumina-forming alloys is poor when the critical Al concentration reaches over 5 wt.%, which may cause serious metallurgical processing problems [13]. To avoid this issue, a protective alumina layer can be applied on the chromia-forming alloy (without Al addition to the alloy itself) by coating the alloy surface with pure aluminium and subsoequently oxidising.…”
