Effect of Temperature on Kinetic Regularities of Forming Nanosized Particles on Steel Surface Contacting with Aqueous Dispersion Medium
Abstract
The specific character of forming nanosized structures on steel surface contacting with air and aqueous dispersion medium in the range of temperatures from 3 to 70°C has been studied. The development of iron-oxygen structures leads to morphological ?-row. As the initial structure the hydroxycarbonate Green Rust under the most conditions has been found. Two branches of phase transformation scheme under full and limited oxidation have been suggested. The optimum condition for forming lepidocrocite is low temperatures (25–35°C) and for forming magnetite is middle ones (50°C). The kinetic regularities of the XRD-pick amounts of lepidocrocite and magnetite from temperatures were calculated.References
