Metal dusting is an aggressive form of high-temperature corrosion that is becoming increasingly relevant in times of steadily growing H2 demand. It occurs in carbon-rich and oxygen-poor atmospheres, such as those typically found in synthesis gas production (H2 + CO), in the temperature range between 400 and 800 degrees. All conventionally used structural materials (Ni and Fe alloys) are affected by this attack and catalyze it. As a rule, metal dusting is accompanied by an incubation period that is difficult to predict and then leads to very rapid degradation of the metallic materials. This leads to spontaneous failures and system downtimes, resulting in high costs.
This presentation will first discuss the phenomenon of metal dusting and its dependence on process parameters such as pressure, temperature and composition of the atmosphere. The latest development trends in the field of alloy and coating design to reduce metal dusting will then be presented. The latest research results of Junior Professor Dr.-Ing. Anke Silvia Ulrich from the University of Bayreuth, who specializes in the development of materials for extreme environments, will also be discussed. Ms. Ulrich will share her experiences and findings during the lecture and will be available for questions at the end of the talk. It is an opportunity not to be missed to learn about the latest developments and challenges in this field.
