The surface of raw Al powders (Figure 2a) is Coatings 2018, 8, 200 4 of 9 reaction rate is accelerated by the high concentration of Ni2+, and the reaction time is extended due to the low removal rate of the Al2O3 layer. Thus, more metallic Ni can be deposited on the surface of...

An X-ray diffraction analysis of the surface revealed that the main corrosion products were hematite (Fe2O3), braunite (Mn2O3), and hausmannite (Mn3O4), and binary oxide spinels were also identified, such as galaxite (MnAl2O4) and jacobsite (MnFe2O4). This is due to the higher ...
As the oxidation progressed, the scale changed from α-Al2O3 to the (α-Al2O3, Fe2O3)-mixture, which provided the necessary oxidation resistance. Keywords: hot-dip aluminizing; P91 steel; oxidation; Al-Fe intermetallics; α-Al2O3 1. Introduction The 9Cr-1Mo ferritic steel (ASTM P91...
They could be ascribed to Al+3, though the position of the peak is slightly shifted towards lower binding energy in comparison with published data for alpha Al2O3 [41]. This shift is probably due to the presence of other metals in the spinel structure. In all samples, potassium occurred ...
The Fe3O4 layer decomposed by a reduction reaction with Al-Mn molten alloy, constituent elements of steel dissolved into a liquid, and the reaction-layer nucleus was formed toward the liquid phase. A coated layer consists of a solidified layer of Al and Al6Mn and a reactive layer formed ...
