1. Analysis of stereometric features of surfaces after abrasive processes with the use of the new parameters of evaluation
Sammanfattning : .... LÄS MER
2. Telementoring Physics: University-Community After-school Collaborations and the Mediation of the Formal/ Informal Divide
Sammanfattning : For several decades improvement of science education has been a major concern of policy makers concerned that the U.S. is a “nation at risk” owing to the dearth of students pursing careers in science. LÄS MER
Sammanfattning : Thin film growth from the vapor phase has for a long time intrigued researchers endeavouring to unravel and understand atomistic surface processes that govern film formation. Their motivation has not been purely scientific, but also driven by numerous applications where this understanding is paramount to knowledge-based design of novel film materials with tailored properties.

4. Failure mechanisms in APS and SPS thermal barrier coatings during cyclic oxidation and hot corrosion
Sammanfattning : Thermal Barrier Coatings (TBCs) are advanced material systems that are being used in the hot sections of gas turbines such as combustor, turbine blades, and vanes. The top ceramic coating in TBCs provides insulation against the hot gases and the intermediate metallic bond coat provides oxidation and corrosion resistance to the underlying turbine components.

Sammanfattning : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. LÄS MER
