Abstract
Described are techniques for treating metals by exposing the metals to reactive solutions to reduce a temperature of the metal and to modify a surface of the metal through chemical reaction, such as by removing material or adding material. The disclosed techniques may advantageously increase the rate at which the temperature of the metal may be reduced as compared to conventional cooling techniques involving pure water, increase metal manufacturing rates, and reduce overall complexity of a metal manufacturing process. The disclosed techniques may also advantageously expand the range of available surface treatments, allow for faster surface treatment processes, and reduce or eliminate the use of hazardous chemicals during a surface treatment process. Such advantages may arise by employing chemical processing that takes place or takes place more efficiently at elevated temperatures.
