With a total of 2 patents, his work has implications for various industries that rely on steel components.

Latest Patents

Coester's latest patents include a method for forming an anticorrosive oxide layer on steels. This innovative method involves subjecting the steel surface to superheated steam for a period ranging from one to several hours. Prior to this treatment, the steel surface is exposed to a gaseous formic acid atmosphere at elevated temperatures of up to 480°C. The process ensures that the steel is treated under specific conditions, maintaining a temperature between 450°C and 520°C with a Reynolds number greater than 900 during steam flow-through conditions.

Another significant patent is the process for the formation of an anticorrosive oxide layer on maraging steel. In this method, a clean steel surface is initially heated to at least 200°C in a nitrogen, air, or oxygen atmosphere before being subjected to superheated steam. Similar to his other patent, this treatment also maintains a temperature between 450°C and 520°C under turbulent steam flow conditions.
