  2. 1. Silicon nitride for total hip replacements

    Author : Maria Pettersson; Cecilia Persson; Håkan Engqvist; Staffan Jacobson; Kenneth Holmberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SiNx; Si3N4; coatings; CoCr; Ti; alloy; tribology; wear; corrosion; dissolution; debris; hip; arthroplasty; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : 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%. READ MORE

  4. 2. Growth and characterization of TiN/SiNx multilayer thin films

    Author : Hans Söderberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Abstract : The demands from industry for higher cutting speeds, feeding rates, and reduction of the use of cooling agents during turning and milling operations are increasing. Consequently the requirements on the cutting inserts are increasing and new advanced coatings that can withstand the higher temperatures and larger loads are highly sought after. READ MORE

  5. 3. Aberration-Corrected Analytical Electron Microscopy of Transition Metal Nitride and Silicon Nitride Multilayers

    Author : Amie Fallqvist; Per Persson; Lars Hultman; Linköpings universitet; []
    Keywords : ;

    Abstract : Two multilayer thin films have been studied: TiN/SiNx and ZrN/SiNx. A double-corrected transmission electron microscope (TEM) was utilized for imaging and spectroscopy. Imaging was carried out in scanning mode (STEM) for all samples. READ MORE

  6. 4. Growth and Characterization of Ti-Si-N Thin Films

    Author : Axel Flink; Lars Hultman; Paul Mayrhofer; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical transmission electron microscopy; Arc; Sputtering; Hard coatings; Multilayer Cutting inserts; analytisk transmissionselektronmikroskopi; ytbeläggningar; skärande; bearbetning; Ti-Si-N; arcförångning; sputtring; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : Utvecklingen inom materialforskningen går mot att framställa avancerade material vilka är skräddarsydda för olika tillämpningar. Detta har medfört att det blir allt mer populärt att belägga ytor med ett eller flera tunna lager med syfte att förbättra materialegenskaperna. READ MORE
