  2. 1. On wear of wood-cutting tools : Tool materials, wear mechanisms and modelling

    Author : Johan Nordström; []
    Keywords : Tool material; Wood cutting; Wear; Modelling;

    Abstract : Bandsaw blades are commonly used in the sawmill industry for timber cutting. The saw teeth are gradually worn during cutting and will finally cause unacceptable surface roughness and dimensional deviations on the sawn wood product. Maintenance by re-sharpening of the saw teeth is therefore necessary after a certain time of sawing. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Micro-scale studies of wear

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

    Abstract : 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.

  6. 4. Engineering Ceramics for Tribological Systems. Manufacture, Properties and Testing

    Author : Lars Kahlman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal wear; ceramic composite; face seal; engineering ceramic; erosion; hybrid bearing; thermal spalling; lubrication; tribology; abrasive waterjet; abrasive wear;

    Abstract : A broad range of commercial and experimental grades of ceramics and ceramic composites was tested in various model tests and simplified component tests. The tests were done to establish important microstructural features, friction and wear mechanisms. READ MORE

  7. 5. Wear in cone crusher chambers

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

    Abstract : 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. READ MORE
