  1. 1. Thermomechanical characterisation of newly developed UHMWPE composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Petra Jan; [2019]
    Keywords : UHMWPE; nanocomposites; thermomechanical characterisation;

    Abstract : Ultra high molecular weight polyethylene (UHMWPE) is a polymer commonly used in various applications, particularly in hip joint replacements. Despite its good performance, it is susceptible to oxidation degradation, which can be mitigated with the addition of vitamin E, and to excessive wear against metal countersurfaces, which can potentially be improved with the addition of nanoparticles.

  2. 2. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Caroline Lejonklo; [2019]
    Keywords : Lean steel; Powder metallurgy PM ; Powder metallurgy steel PM steel ; Friction; Wear; Sliding contact; Lubricated; Porosity; Tribology; Adhesive wear; Abrasive wear; Gear; Gear tooth; Particles; Polyalphaolefin 8 PAO 8 ; Contact pressure; Density; Light optical microscopy LOM ; Scanning electron microscopy SEM ; Energy-dispersive X-ray spectroscopy EDS ; Vertical svanning interferometry VSI ; Pin on disc; Pin-on-disc;

    Abstract : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

  3. 3. Tribological characterisation of turbocharger turbine sealing rings in heavy duty diesel engines

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik; Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Alex Goussakov; Alin Dumitru Durac; [2018]
    Keywords : Tubine sealing rings;

    Abstract : This work investigated the wear mechanisms of turbocharger components in heavy duty diesel engines. By understanding the wear mechanisms that are occurring in turbochargers the life time of the turbocharger components can be improved. READ MORE

  4. 4. Investigation of wear behavior of different sliding bearing materials in an alkaline environment

    University essay from

    Author : Martina Ottosson; [2018]
    Keywords : wear; tribology; alkaline; sliding bearing;

    Abstract : In sliding bearing wear is a very common problem and can be affected by several factors. The wear in a bearing can lead to total failure of the component and lower the lifetime. In a sliding bearing used in a machine in the pulp and paper industry large wear has been detected, but no clear evidence of what the wear depends on. READ MORE

  5. 5. Metal-on-Polymer Wear for Orthopaedic Hand Prostheses : Metall-på-polymer-slitage för ortopediska handproteser

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : CHLOE TECHENS; [2018]
    Keywords : orthopaedics prosthesis arthrosis trapezometacarpal biomaterial tribology friction wear;

    Abstract : Metal-on-polymer prostheses in orthopaedics are often subject to high wear level producing large polyethylene particles that the body has difficulties to eliminate. Those debris can lead to prosthesis loosening. READ MORE
