21. Physical vapor deposition and thermal stability of hard oxide coatings
Sammanfattning : The state-of-the-art tools for machining metals are primarily based on a metal-ceramic composite (WC-Co) coated with different combinations of carbide, nitride, and oxide coatings. Combinations of these coating materials are optimized to withstand specific wear conditions. LÄS MER
22. A study of some aspects of gas-slag-metal interactions : Towards dynamic process model and control
Sammanfattning : The present thesis deals with the development of a new type of dynamic model for metallurgical reactors. It also covers some of the theoretical aspects of steelmaking that is necessary to include in such an application. The thesis consists of modeling work, high temperature experiments and cold model experiments. LÄS MER
23. Novel approaches for achieving full density powder metallurgy steels
Sammanfattning : Powder metallurgy (PM) is one of the most resource-efficient methods for manufacturing structural components with complex shapes. The utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. LÄS MER
24. Nanoplasmonic Alloy Hydrogen Sensors
Sammanfattning : The hydrogen economy proposes hydrogen gas as the main energy carrier thanks to its high energy density and the possibility to produce it in a sustainable way without CO2 emission. However, the wide flammability range of hydrogen-air mixtures dictates that hydrogen sensors will be a mandatory accessory to any appliance or vehicle fueled by hydrogen. LÄS MER
25. Investigation of corrosion properties of metals for degradable implant applications
Sammanfattning : Nedbrytbara metaller utgör en ny klass av biomaterial med potential attersätta permanenta material i tillfälliga applikationer. Detta för att minskarisken för långvariga biverkningar. LÄS MER
