Effects of Al2O3 Nano-additive on Performance of Micro-arc Oxidation Coatings Formed on AZ91D Mg Alloy

Fabrication of graphene oxide–alumina hybrids to reinforce the anti-corrosion performance of composite epoxy coatings

“…Among the diverse inorganic nanoparticles, Aluminum oxide (nano-Al 2 O 3 ) is widely used in the field of ceramics, coating, rubber, and plastic industries for its superior hardness, chemical stability, low price and well corrosion resistance [25,26]. While there are many examples of other nanoparticles used for grafting GO, such as silica, titanium oxide, and zinc oxide [4,24,27], there are relatively few reports that mention GO grafted with nano-Al 2 O 3 .…”

Microstructure and properties of rare earth CeO2-doped TiO2 nanostructured composite coatings through micro-arc oxidation

“…Most investigations mainly focused on the influence of voltage on the MAO process, whereas others have indicated that the current density also has a significant effect on the MAO process [14][15][16][17]. Moreover, to improve the performance of MAO coatings further, nanoparticles such as ZrO 2 [18], Al 2 O 3 [19], and TiO 2 [20] are added in the electrolyte to form composite films. However, doping coatings with cerium oxide nanoparticles on TiO 2 MAO coatings have not been evaluated.…”

Improvement of energy efficiency in the operation of a thermal reactor with submerged combustion apparatus through the cyclic input of energy

“…3) it provides the possibility to achieve the condition, optimal for friction, with improved surface hardness and plastic core [17].…”
