1. A Study of the Adhesion Strength of Plasma Sprayed Coatings
Sammanfattning : Surface preparation prior to thermal spraying is a key factor in ensuring a good adhesion of the coating onto the part to be coated. Surface pre-treatment conditions and methods have mainly been developed experimentally and have changed little over the years. LÄS MER

Sammanfattning : .... LÄS MER
3. A Methodology to Control the Microstructure of Plasma Sprayed Coatings
Sammanfattning : The aim of this thesis is to enhance the overall understanding of the plasma spray process and increase control and reproducibility of the coating properties. This was performed by establishment of relationships between controllable process parameters, in-flight properties of the injected particles (velocity and temperature), and microstructure properties.

4. High-temperature degradation of plasma sprayed thermal barrier coating systems
Sammanfattning : Thermal barrier coating systems (TBCs) are used in gas turbines to prevent high-temperature degradation of metallic materials in the combustor and turbine. One of the main concerns regarding TBCs is poor reliability, and accurate life prediction models are necessary in order to fully utilise the beneficial effects of TBCs. LÄS MER
5. Design of Suspension Plasma Sprayed Thermal Barrier Coatings
Sammanfattning : Thermal barrier coatings (TBCs) are widely used on gas turbine components to provide thermal insulation, which in combination with advanced cooling, can enable the gas turbine to operate at significantly higher temperatures even above the melting temperature of the metallic components. There is a permanent need,mainly due to environmental reasons, to increase the combustion temperature inturbines, hence new TBC solutions are needed. LÄS MER
