6. Modification of Float Glass Surfaces by Ion Exchange
Sammanfattning : Glass is a common material in each person’s life, e.g. drinking vessels, windows, displays, insulation and optical fibres. By modifying the glass surface it is possible to change the performance of the entire glass object, generally known as Surface Engineering. LÄS MER

8. Grinding effects on surface integrity, flexural strength and contact damage resistance of coated hardmetals
Sammanfattning : The tribological and mechanical behavior of coated tools depends not only on intrinsic properties of the deposited film but also on substrate surface and subsurface properties – such as topography and residual stress state – as well as on interface adhesion strength. It is particularly true in the case of coated tools based on WC-Co cemented carbides (backbone materials of the tool manufacturing industry, and simply referred to as hardmetals in practice) as substrates.

9. Spark plasma sintered ZrO2-SiO2 glass ceramics and Si3N4 bioceramics
Sammanfattning : This thesis focuses on elaboration and characterization of two types of bioceramics: one is ZrO2-SiO2 nanocrystalline glass ceramic (NCGC) for dental application. The goal is to develop new ZrO2-SiO2 NCGCs with a combination of high strength and high translucency; the other is biodegradable Si3N4 ceramics for spinal fusion. LÄS MER
10. Micromechanical retention and chemical bonding to polycrystalline dental ceramics : studies on aluminum oxide and stabilized zirconium dioxide
Sammanfattning : Det pågår en ständig utveckling av olika dentala material avsedda föratt ersätta förlorad tandsubstans. En materialgrupp som är särskiltintressant är höghållfasta keramiska material, oxidkeramer så somyttriumdioxidstabiliserad tetragonal polykristallin zirkoniumdioxid(Y-TZP). LÄS MER
