Fabrication of thick gel-like films by anodizing iron in a novel electrolyte based on dimethyl sulfoxide and H2SiF6

Corrosion Resistance of Anodic Layers Grown on 304L Stainless Steel at Different Anodizing Times and Stirring Speeds

“…From the charge density values, the theoretical thickness of the anodic layer can be estimated assuming that the entire charge is used for the formation of FeOOH, acoording to Equation (1) This compound has been previously reported as the main component of the anodic layers grown in ferrous materials [35,41,49]. Figure 3 shows the current density-time curves recorded during the anodizing treatments at 0 rpm and at 600 rpm for different anodizing times (15,30,45, 60 min).…”

“…Nevertheless, most of the existing works so far are focused on the growth and chemical/ morphological characterization of the anodic layers on these ferrous materials [29,35,[39][40][41][42], but not on their influence on the electrochemical response or corrosion resistance properties. For that reason, the objective of this work is to explore the corrosion properties in a NaCl solution of the anodic layers grown on 304L SS at different stirring speeds and anodizing times inthylene glycol with 0.1 mol L −1 NH 4 F and 0.1 mol L −1 H 2 O.…”

“…Nevertheless, most of the existing works so far are focused on the growth and chemical/ morphological characterization of the anodic layers on these ferrous materials [29,35,[39][40][41][42], but not in the electrochemical degradation to which these materials may be subjected . For that reason, the objective of this work is to explore the corrosion electrochemical response of anodic layers grown on 304L SS at different stirring speeds and anodizing time using an ethylene glycol-0.1 M NH4F-0.1 M H2O electrolyte, in order to be able to glimpse what would be its behavior in chlorides rich solutions.…”

Preparation of Fe2O3/Fe foils by anodic oxidation in saturated NaF solution and calcination

“…dimethyl sulphoxide and ethylene glycol) are usually selected to prepare porous iron oxides. [16][17][18][19] In these electrolytes, the water plays an important role in the formation of iron oxides. 16,17 Rangaraju et al 20 have proposed two aqueous electrolytes (NaBF 4 and NH 4 F) contained Na 5 P 3 O 10 or Na 2 B 4 O 7 to form nanostructure iron oxide by anodisation at room temperature.…”
