High temperature corrosion
At high temperatures, usually above 300-400°C, most gases cause corrosive attack in metals. The biggest problems arise in the presence of aggressive gases such as CO, H2S, SO2, Cl2 and HCl. Besides oxidation, metals and alloys can be subject to nitriding, sulphidation, carbonisation, chloriding, etc. Corrosion problems often arise in combustion environments, e.g. biomass or waste-fuelled CPH plants, aircraft engines, gas turbines, as well as in heat-treatment applications and in refineries.
We conducts several research projects within this area, within the framework of, among others, the Competence Centre for High Temperature Corrosion (HTC), Consortium Materials Technology for Demonstration and Development of Thermal Energy Processes (KME) and Värmeforsk. Important resources for our research and development activities include our well-equipped laboratories, where we are able to simulate relevant high-temperature application environments.
In this area, we also offer advisory services concerning failure analysis, materials selection, corrosion testing and more.
For companies that own, operate or build combustion plants, we also lead a "Corrosion network for combustion plants". Membership in the network is also open to other companies in this sector, e.g. service providers, and equipment and materials suppliers.
