    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D printing; apatite; biomaterials; biomineralisation; bone; bone quality; canaliculi; CoCr; collagen; electron beam melting; electron microscopy; implant; interface; in vivo; lacuna; micropetrosis; osseointegration; osteocyte; Raman spectroscopy; surface modification; Ti6Al4V; titanium; ultrastructure; whitlockite;

    Abstract : By virtue of certain design features, bone anchored metal implants can be made to elicit a strong initial osteogenic response, i.e., the amount of bone formed. READ MORE

  4. 2. 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

  5. 3. Tribological behaviour of HVAF-sprayed WC-based coatings: : Role of process variables and binder chemistry

    Author : Kaveh Torkashvand; Mohit Kumar Gupta; Shrikant V. Joshi; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribological Behaviour; HVAF; WC-Based Coatings; Process Variables; Binder Chemistry; Tribologisk Prestanda; HVAF; WC-baserade Beläggningar; Parametervariabler; Bindemedelskemi; Production Technology; Produktionsteknik;

    Abstract : Tungsten carbide (WC) based metallic matrix coatings sprayed using high velocity air fuel (HVAF) technique have attracted increasing attention as they show excellent tribological performance in various wear conditions. In the HVAF method, particles’ in-flight temperature and velocity can be influenced by the process variables including nozzle configuration as well as feedstock particle size range. READ MORE

  6. 4. On cobalt-chrome frameworks in implant dentistry

    Author : Lars Hjalmarsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cobalt-chrome; titanium; implants; misfit; corrosion; viability; abutment-free;

    Abstract : Background: Cobalt-chrome (CoCr) alloys have been used in dentistry in decades but very little is known about their behavior and biological impact as framework materials in implant dentistry. Furthermore, few studies have evaluated and compared the clinical and radiological results of abutment and abutment-free implant treatment concepts. READ MORE

  7. 5. Towards more sustainable approaches for protecting surfaces against wear

    Author : Kaveh Torkashvand; Mohit Kumar Gupta; Nuria Espallargas; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; HVAF spraying; WC-Based Coatings; Sustainability; Binder Chemistry; Slitage; HVAF; WC-baserade beläggningar; Hållbar produktion; Bindemedelskemi; Production Technology; Produktionsteknik;

    Abstract : WC-Co coatings, with and without chromium additives, are widely used in the industry for severe tribological applications. However, concerns about cobalt supply and its environmental and health impacts have led industries to explore sustainable binder alternatives. READ MORE
