Chromium oxide (Cr203) ceramic coatings are a type of industrial coating applied using flame spray or plasma electric arc coating services. Cr203 coatings are highly effective for providing seal surfaces, improving abrasion, and …
The results showed that the corrosion current density values of chromium oxide coatings (0.4-1.2 μA/cm²) were of the same order of magnitude as Ti-6Al-4V alloy. Mechanical abrasion did not increase corrosion rates of chromium oxide coatings but did for uncoated Co-Cr-Mo and Ti-6Al-4V. The impedance response of chromium oxide coatings was very ...

that the formed nano metal oxide is pure Cr 2 O 3 and having hexagonal structure. Sharpness of the peaks shows good crystal growth of the oxide nanoparticles. Average particle size (t) of the particles have been calculated using from high intensity peak using the Debye-Scherrer equation t = K / B cos Where 't' is the average crystalline size of
Chromium oxide is a well known catalyst for the complete oxidation of chlorinated hydrocarbons due to its high removal activity [1-5 ]. The commercial application of this catalytic system, however, has been limited by fear about the evaporation of Cr during the course of reaction, especially at high feed concentrations of chlorinated compounds ...

Cerium oxide (CeO2) is amongst the most used rare earth compounds [78]. In fact CeO 2 nanoparticles are most commonly used in the biomedical field as catalysts [79] and antioxidants [78]. Few plant-mediated syntheses have been conducted, where CeCl 3 [80] and cerium (III) nitrate hexahydrate [78] were used as precursors.
The texture and chemistry of chromium oxide nanocrystals were characterized by N2 adsorption-desorption isotherms, FTIR, X-ray diffraction (XRD), UV-vis, and thermoanalytical methods. It was shown that the hydrate water and CA are the crucial factors in influencing the formation of mesoporous Cr2O3 nanocrystals in the mixture system.
Transition metal oxide NPs have many applications as catalyst [1-5], sensors [6-9], superconductors [10-11] and adsorbents [12-13]. Metal-oxides constitute an important class of materials that are involved in environmental science, electrochemistry, biology, chemical sensors, magnetism and other fields. Chromium
