11. Novel Insights into the Oxidation of High Temperature Alloys - The Role of Environment, Microstructure and Reactive elements
Sammanfattning : The properties of materials can be deteriorated, when they react with an environment at high temperature and form various types of corrosion products, such as oxides and nitrides. In order to perform successfully at elevated temperatures, all these materials are required to be protected by a slow-growing, continuous and adherent surface oxide layer. LÄS MER
12. Corrosion of High-Temperature Alloys in Molten Salts
Sammanfattning : Concentrated solar power (CSP) is an interesting technology that involves storing solar energy in the form of heat and subsequently converting it into electricity. The third-generation (Gen3) CSP plants aim to operate at temperatures >700°C, necessitating the deployment of new heat storage materials that can withstand such high operating temperatures. LÄS MER
13. Microscopy of high temperature oxidation of iron and some stainless steels
Sammanfattning : This thesis concerns the high temperature oxidation of iron and some stainless steels. The oxide scales, as well as the subjacent metal, were investigated using a range of electron and ion microscopy techniques, including SEM, TEM, EDX and FIB. The aim was to link the microstructural observations to the oxidation mechanisms of the materials. LÄS MER
14. The influence of SO2 on the high temperature corrosion of Fe and Fe-Cr alloys
Sammanfattning : Sulfur dioxide is an important pollutant in combustion gases and plays a major role in the high temperature corrosion of many metals and alloys. This work investigates the influence of small amounts of SO2 on the high temperature corrosion of iron, chromium and several Fe-Cr alloys. LÄS MER
15. High temperature corrosion of some selected stainless steels and Ni-base alloys – an advanced microscopy study
Sammanfattning : The thesis deals with high temperature corrosion behavior of some selective stainless steels and Ni-base alloys with applications in power generation technologies, e.g. boilers fired by biomass and waste. LÄS MER
