Description
Summary:Change in the chemical composition and structure of the FeCrAl alloy surface after various preliminary activations has been studied using scanning electron microscopy. The influence of activation way on alloy reactivity relative to aggressive 1,2-dichloroethane vapors was investigated at 550 and 700°C. The redox and acid treatment of alloy, as opposed to high-temperature calcination and alkaline etching, was shown to form active centers on its surface, so that these centers are responsible for carbon erosion to obtain carbon nanofibers.
