The Preparation of Combined Aluminium Oxide Coatings on Aluminium Substrate
T h e prepara t ion and propert ies of combined a luminium oxide coatings have been investigated. T h e coating has been prepared in two steps. First , a luminium subs t ra te was anodically oxidized. In t he next s tep the anodized film has been coated by the sol-gel method . T h e condit ions of forming coatings wi thout shrinkage were obta ined empirically. It was found out t h a t the film ...

متن کاملSynthesis of graphene oxide-TiO2 nanocomposite as an adsorbent for the enrichment and determination of rutin
Objective(s): In our study, graphene oxide-TiO2 nanocomposite (GO/TiO2) was prepared and used for the enrichment of rutin from real samples for the first time. Materials and Methods: The synthesized GO/TiO2 was characterized by X-ray diffraction, scanning electron microscopy, and FT-IR spectra. The enrichment process is fast and highly efficient. The factors including contact time, pH, and...
متن کاملAnodic oxide formation on aluminium-terbium alloys
Aluminium terbium alloys were prepared by simultaneous thermal evaporation resulting in a thin film library covering a 5 to 25 at.% Tb compositional spread. Synchrotron x-ray diffraction (XRD) proves all of the alloys to be amorphous. Scanning electron microscopy (SEM) measurements reveal the structural changes upon increase in Tb content with the formation of small, Tb-rich segregations right ...
متن کاملAluminium oxide ( corundum , emery , sapphire / ruby )
Next to the main aluminium ore, bauxite, an assemblage of aluminium hydroxides, aluminium oxides and other minerals (gibbsite, diaspore, boehmite, kaolinite, quartz, hematite, goethite, rutile, anatase, and alumogel), aluminium oxides find direct application in diverse industrial processes (e.g., refractory, abrasives, and watch-making industries) as well as in the gemstone sector. Corundum (Al...
