  1. 11. Micromechanical retention and chemical bonding to polycrystalline dental ceramics : studies on aluminum oxide and stabilized zirconium dioxide

    Författare :Evaggelia Papia; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alumina; aluminium oxide; bond strength; oxide ceramics; polycrystalline dental ceramics; stabilized zirconium dioxide; Y-TZP; zirconia; adhesive cements;

    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

  3. 12. Defects in Titanium Aluminum Nitride-Based Thin Films

    Författare :Janella Salamania; Magnus Odén; Lars Johnson; Lina Rogström; Zoe Barber; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thin films; Ti-Al-N; Defects; Physical vapor deposition;

    Sammanfattning : Coatings and thin films inherently contain several types of defects. This thesis aims to enhance the understanding of the relationship of defects on the growth, structure, stability, and properties of titanium aluminum nitride films synthesized by physical vapor deposition techniques.
