1. Oxidation kinetics of nickel particles
Sammanfattning : Nanoparticles have an immense surface to volume ratio. This is a key factor to the new properties of some materials made up of such particles. The oxide layer formed on all materials will have a large influence on the behaviour of these materials. The layer isadvantageous in some cases but causes problems in other. LÄS MER
2. On high temperature oxidation resistance : Towards the materials genome of high temperature alloys
Sammanfattning : The efficiency of a heat engine increases with increasing service temperature. This leads to a demand for material that can withstand aggressive environments and sometimes also high load at higher and higher temperature. That is the rationale for the work of this thesis. LÄS MER
3. Performance of High-temperature Coatings : Oxidation and Interdiffusion
Sammanfattning : The use of aluminiferous coatings profoundly improves the service life of superalloys but leads to the microstructural degradation of superalloys and thus the loss of mechanical properties. To solve this trade-off, two strategies were employed in this research. LÄS MER
4. High Temperature Corrosion of FeCrAl Alloys: The influence of water vapour and alkali salt
Sammanfattning : The corrosive environment in biomass- and waste-fired boilers has been known for several years. The traditionally used FeCr and FeNiCr steels show limited performance in the aggressive environment that contains more H2O and alkali salts than traditional fuel. LÄS MER
