1. Mechanical Behaviour of Gas Turbine Coatings
Abstract : Coatings are frequently applied on gas turbine components inorder to restrict surface degradation such as corrosion andoxidation of the structural material or to thermally insulatethe structural material against the hot environment, therebyincreasing the efficiency of the turbine. However, in order toobtain accurate lifetime expectancies and performance of thecoatings system it is necessary to have a reliableunderstanding of the mechanical properties and failuremechanisms of the coatings.

2. Material Solutions for Mitigating High Temperature Corrosion in Biomass- and Waste-fired Boilers - Utilizing Novel FeCrAl Alloys and HVAF-sprayed Ni-based Coatings
Abstract : 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.

3. High Temperature Corrosion of Superheaters in Biomass - and Waste-Fired Boilers: Combat on two fronts
Abstract : Carbon dioxide is a greenhouse gas contributing to the greenhouse effect and a significant contribution comes from the use of fossil fuels. Utilizing more renewable fuels is therefore a solution to decrease the net release of CO2 emissions to the atmosphere. READ MORE
