Corrosion resistance of α- and (α + β)-Brasses in a descaling solution by a mixture of imidazole and hexadecyltrimethylammonium bromide

Selective Aerobic Oxidation of Toluene in the Presence of Co2+ and Task-Specific Organic Salts, Including Ionic Liquids

“…The beneficial, inhibiting effects of organic ammonium bromides and imidazolium-based bromides have also been observed in the case of other materials, e.g., cetyltrimethylammonium bromide 37 or [C 16 MxIm][Br] imidazolium-based ILs 38 and mild steels, as well as with hexadecyltrimethylammonium bromide and brasses. 39 The results obtained by the immersion method are in good accordance with the visual observations and the microscopic studies. High corrosion rates of the steels exposed to the reaction mixtures containing trimethylphenylammonium tribromide were noted, where massive corrosion on the whole surface of the studied samples was observed both macroscopically (Figure 3) and microscopically (Figure 4).…”

“…Therefore, the organic bromide salts exhibit a corrosion inhibition effect and they may be considered as corrosion inhibitors for the studied steels. The beneficial, inhibiting effects of organic ammonium bromides and imidazolium-based bromides have also been observed in the case of other materials, e.g., cetyltrimethylammonium bromide or [C 16 MxIm]­[Br] imidazolium-based ILs and mild steels, as well as with hexadecyltrimethylammonium bromide and brasses …”

Pumpkin Leaf Extract Crop Waste as a New Degradable and Environmentally Friendly Corrosion Inhibitor

“…C dl and C f are calculated using the following equations: − C = Y 0 ω n − 1 = Y 0 false( 2 π f zim − Max ) n − 1 where f (zim‑Max) denotes the maximum of frequency in the imaginary part of the impedance spectrum. Moreover, based on the Helmholtz model, there are expressions for C f and C dl as follows: ,− C dl = ε 0 ε d S C f = F 2 S 4 R T where ε 0 and ε denote the partial dielectric constant of the air and bilayer, respectively, d denotes the thickness of the bilayer, S denotes the surface area, and F denotes the Faraday constant. The water molecules are gradually replaced by PLE molecules to form an adsorption film with the addition of content of the PLE, resulting in a smaller surface area of the bare copper and a thicker bilayer.…”

Insights into the Corrosion Inhibition Mechanism of Canavalia gladiata Leaf Extract for Copper in Sulfuric Acid Medium

“…Based on the fitted linear regression coefficient, one can conclude that the adsorption of CGLE can be judged by the Langmuir adsorption. The following formula was used for calculation − K normala normald normals = 1 55.5 exp ( − Δ G a d s 0 R T ) …”
