  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. Microstructural aspects on wear of cemented carbides

    Author : Håkan Engqvist; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Materialvetenskap; Materials Science;

    Abstract : Cemented carbides are known to be very wear resistant and are therefore often usedin applications involving surface damage and wear. The work presented hereinvestigates the coupling between the microstructure and some fundamental wearand deformation mechanisms typical for cemented carbides. READ MORE

  5. 3. Low Friction and Wear Resistant Carbon Nitride Thin Films for Rolling Components Grown by Magnetron Sputtering

    Author : Konstantinos D. Bakoglidis; Lars Hultman; Grzegorz Greczynski; Susann Schmidt; Esteban Broitman; Tomas Kubart; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The scope of this licentiate thesis is the investigation of carbon based thin films suitable for rolling components, especially roller bearings. Carbon and carbon nitride are materials with advantageous tribological properties and high resiliency. READ MORE

    Keywords : Hydroxyacrylate-melamine copolymer; cellulose nanocrystals CNC ; cellulose nanofibrils CNF ; Electrochemical impedance spectroscopy EIS ; atomic force microscopy AFM ; corrosion protection performance; water uptake; nanomechanical and nano-wear properties; coating; nanocomposite.; Hydroxyakrylat-melamin-sampolymer; cellulosananokristaller CNC ; cellulosananofibriller CNF ; Elektrokemisk impedansspektroskopi EIS ; atomkraftsmikroskopi AFM ; korrosionsskyddsprestanda; vattenupptag; nanomekaniska egenskaper och nano-slitage; coating; nanokomposit.; Kemi; Chemistry;

    Abstract : Corrosion protection is commonly achieved by applying a thin polymer coating on metal surfaces. In this doctoral thesis, a waterborne hydroxyacrylate-melamine copolymer coating was used for this purpose. The first step was to find the optimal curing conditions. READ MORE

  7. 5. Investigation of hafnium for biomedical applications : corrosion and tribocorrosion in simulated body fluids

    Author : Jorge Rituerto Sin; Ardian Morina; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Metals have excellent properties, such as high strength, ductility and toughness, which make them the material of choice for many biomedical applications. However, the main drawback of metals is their general tendency to corrode, which is an important factor when they are used as biomaterials due to the corrosive nature of the human body. READ MORE
