21. Calcium-Aluminate as Biomaterial : Synthesis, Design and Evaluation
Sammanfattning : In this thesis different aspects of calcium-aluminate (CA) as biomaterial are presented. Calcium aluminate is a chemically bonded ceramic with inherent properties making it suitable for use as biomaterial in some applications. LÄS MER
22. WC grain growth during sintering of cemented carbides : Experiments and simulations
Sammanfattning : Cemented carbides are composite materials consisting of a hard carbide and a ductile binder. They are powdermetallurgically manufactured, where liquid-phase sintering is one of the main steps. The most common cemented carbide consists of WC and Co and it is widely used for cutting tools.

23. Additives Increasing the Bone-Forming Potential around Calcium Phosphate Cements : Statin, Strontium and Silicon
Sammanfattning : More than one million people worldwide receive some kind of bone graft each year. Grafts are often needed following bone tumour removal or traumatic fractures to fill voids in the bone and to aid in the healing process. LÄS MER
24. Friction and Wear Mechanisms of Ceramic Surfaces : With Applications to Micro Motors and Hip Joint Replacements
Sammanfattning : Surfaces exposed to wear always transform and typically a layer of new structure and composition is formed. This layer, often called tribofilm, changes the friction and wear properties. LÄS MER
25. Silicon nitride for total hip replacements
Sammanfattning : For more than 50 years total hip replacements have been a common and successful procedure to increase patient mobility and quality of life. The 10-year implant survival rate is 97.8%. LÄS MER
