6. Carbon reinforced UHMWPE composites for orthopaedic applications : characterization and biological response to wear particles
Sammanfattning : Joint replacements have considerably improved the quality of life of patients with joints damaged by disease or trauma. However, problems associated with wear particles generated due to the relative motion between the components of the bearing are still present and can lead to the eventual failure of the implant.

7. Synthesis and Characterization of Amorphous Carbide-based Thin Films
Sammanfattning : In this thesis, research on synthesis, structure and characterization of amorphous carbide-based thin films is presented. Crystalline and nanocomposite carbide films can exhibit properties such as high electrical conductivity, high hardness and low friction and wear. LÄS MER
8. Synthesis and Characterization of High Entropy Alloy and Coating
Sammanfattning : High entropy alloys (HEAs) are a new class of alloys that contains five or more principal elements in equiatomic or near-equiatomic proportional ratio. The configuration entropy in the HEAs tends to stabilize the solid solution formation, such as body-centered-cubic (BCC), face-centered-cubic (FCC) and/or hexagonal-closed-pack (HCP) solid solution.

9. Tribology of self-lubricating polymer composites for hydropower applications
Sammanfattning : The ongoing global climate crisis and its impacts calls for urgent actions, such as significant reduction of CO2 emissions by introducing more renewable energy. This has led to a rapid integration of variable power sources, such as wind and solar power, into the electricity systems. LÄS MER
10. Oil consumption and Friction in a Piston Ring-Cylinder Liner assembly.-A multifunctional Surface Approach
Sammanfattning : About a half of the frictional losses in an internal combustion engine come from the interactions between the piston assembly and cylinder liner surface. The tribological considerations in the contact between the piston ring and cylinder liner have attracted much attention over the past few decades. LÄS MER
