21. High Temperature Corrosion Behaviour of Ni-base Alloys and FeCrAl Alloys – The Influence of Water Vapour
Sammanfattning : Electricity production, transportation, and manufacturing industry are some of the largest sources of greenhouse gas emissions. In many cases, these processes are carried out at high temperature and energy efficiency is limited by material degradation, so-called ‘high-temperature corrosion’. LÄS MER
22. Material Solutions for Mitigating High Temperature Corrosion in Biomass- and Waste-fired Boilers - Utilizing Novel FeCrAl Alloys and HVAF-sprayed Ni-based Coatings
Sammanfattning : Combustion of biomass and waste for heat and electricity production is a promising alternative to fossil fuels and is thereby an important step towards a more sustainable future. However, due to substantial amounts of alkali- and chlorine-containing species as well as moisture in biomass and waste, the combustion of these results in a highly corrosive environment which accelerates the degradation of steel components in the boiler, drastically increasing the maintenance costs.

23. Corrosion resistant alumina-forming alloys for lead-cooled reactors
Sammanfattning : Generation IV nuclear power technologies provide attractive solutions to the common issues related to conventional nuclear power plants currently in operation worldwide. Through a significant reduction of the long-term radiotoxicity of nuclear waste, a more efficient use of nuclear fuel resources, and implementation of inherent safety features, Generation IV will make nuclear power sustainable and thus increase the public acceptance of nuclear power.

24. Atmospheric corrosion of copper and copper-based alloys in architecture : from native surface oxides to fully developed patinas
Sammanfattning : Copper and copper-based alloys are commonly used in both ancient and modern architecture. This requires an in-depth fundamental and applied understanding on their atmospheric corrosion behavior at different climatic, environmental and pollutant levels and how these parameters influence e.g. LÄS MER
25. Assessment of bio-based fuel ash effects on magnesia refractory materials in quicklime production kilns
Sammanfattning : Limestone is calcined into quicklime in lime kilns at temperatures above 1000°C. Heat is supplied through combustion inside the kilns, which are insulated with a lining of refractory bricks to mitigate heat loss and to protect the kiln from the hot, chemically aggressive, and mechanically abrasive environment.
