1. High-temperature corrosion properties of chromia- and alumina-forming alloys
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
2. 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
3. Nitrogen and Water in High Temperature Corrosion - Insights from First Principle Calculations
Sammanfattning : Service life-time of alloys used in high temperature applications is often limited by corrosion. FeCrAl(Re) alloys are partially designed to form a protective α-alumina oxide scale at elevated temperatures in order to mitigate further oxidation. LÄS MER
4. 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
5. High Temperature Oxidation and Corrosion of Ni-Based Superalloys for Industrial Gas Turbines
Sammanfattning : High temperature oxidation and corrosion of Ni-based superalloys used for blades in industrial gas turbines was studied using advanced high-resolution electron microscopy methods. Both coated and non-coated alloys were tested. LÄS MER
