Characterization of MAO + Cu Composite Coatings on Aluminum Alloy

Anti-corrosive Properties of CeO2 Conversion Coatings on Aluminum Alloy 2024 Prepared by Dip Immersion Method

As an alternative to chromate conversion coatings, rare-earth coatings especially cerium, because of the low toxicity, have attracted considerable attention. Using dip immersion method, cerium-based conversion coating was deposited on aluminum 2024. Corrosion resistance was studied in 3.5 wt.% NaCl solution using potentiodynamic polarization, electrochemical impedance spectroscopy, and surface ...

Surface Characterization of Adamantylethyltrichlorosilane (AdSi) Coatings on Aluminum

. Surface characterization techniques were used to evaluate adamantylethyltrichlorosilane (AdSi) as a potential coating to provide surface protection or as an initiator for diamond-like thin films. FT-IR and FT-Raman results indicate that, after formation and heating, the coating system has developed a cross-linked siloxane network. Quartz crystal microbalance and contact angle measurements wer...

Microstructure of Metallorganic Chemical Vapor Deposited Aluminum Coatings on Ti6242 Titanium Alloy

EFFECT OF MULTI-STEP ANODIZING METHODS ON THE OPTICAL ABSORPTION OF BLACK COATINGS ON 2024 ALUMINUM ALLOY

 Development of materials with the ideal black body absorption spectrum are of great interest. Such materials could improve the efficiency of solar cells, and passive cooling and heat transfer systems as well as the protective and decorative coatings. Fabricating black anodizing coatings is promising for this purpose because they exhibit low light reflection from the surface. Such coatings can ...

Temperature Effect on Creep and Fracture Behaviors of Nano-SiO2-composite and AlSi12Cu3Ni2MgFe Aluminum Alloy

In the presented article, the temperature effect was studied on creep properties and fracture behaviors of AlSi12Cu3Ni2MgFe aluminum-silicon alloys, unreinforced and reinforced with SiO2 nano-particles. For such objective, standard specimens were fabricated by gravity casting and stir-casting methods, for aluminum alloys and nano-composites, respectively. Then, force-controlled creep...
