    Sammanfattning : Höftprotesoperationer har blivit en mycket vanlig operation med generellt goda resultat. Allt fler och allt yngre patienter opereras vilket ställer högre krav på att höftprotesen fungerar bättre och håller längre så att en omoperation kan undvikas. LÄS MER

  4. 8. A Ni3Al-alloy and its Composites as Potential Wear Resistant Materials for Advanced Applications

    Författare :Karin Anne Xia Gong; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Abrasive wear; Intermetallic matrix composite; Friction coefficient; Wear-resistant materials.; Nickel aluminide; Specific wear rate; Sliding wear;

    Sammanfattning : The Ni3Al-based intermetallic alloys as engineering materials in service, they may be subjected to a wear environment of some sort. Hence, it is technologically important to understand the tribological response and to determine methodologies to improve wear resistance of these advanced materials. LÄS MER

  5. 9. Micro-scale studies of wear

    Författare :Rickard Gåhlin; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Wear; micro-scale; methods; fundamental studies; AFM; micromechanical; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : The development of materials for tribological components is constantly striving to more sophisticated properties, specialised for specific applications. This progress requires and depends to a large extent on a parallel development of the theoretical knowledge of wear and on development of the experimental tools for investigating wear in the research lab as well as in the field.

  7. 10. Wear in cone crusher chambers

    Författare :Mats Lindqvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cone crusher; modelling; wear; rock crusher; work hardening;

    Sammanfattning : Cone crushers are widely used in the mining and aggregates industries to reduce the size of blasted rock. A cone crusher consists of a fixed conic liner called concave and inside it a smaller moving liner called mantle. The mantle is suspended on an eccentrically rotating shaft. LÄS MER
