  2. 11. Correlating Microstructure with Texture of Particulate Biopolymer Gels

    Author : Maud Langton; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microstructure; image analysis; texture; electron microscopy; lactoglobulin; particulate gels; whey protein; light microscopy;

    Abstract : The microstructure of particulate biopolymer gels has been studied to comprehend the effect of microstructure on textural properties. Particulate structures have been characterized at different levels by using light microscopy, scanning electron microscopy, and transmission electron microscopy. READ MORE

  4. 12. Surfaces of Honed Cylinder Liners

    Author : Zlate Dimkovski; B.-G. Rosén; Mohamed El-Mansori; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Honing; Characterisation; Blechmantel; Groove Parameters; Quality Control; Oil Consumption; Wear; Friction; Mixed Lubrication Simulation; Surface engineering; Ytbehandlingsteknik;

    Abstract : Cylinder liner surfaces are often on the agenda of engine developers because of their large influence on the frictional losses, oil consumption and emissions of internal combustion engines. Improving the liner function involves not only manufacturing new surfaces and checking their function but also characterising them as a necessary intermediate step for better understanding of the changes made.

  5. 13. Characterisation of Functional Pressing Die Surfaces

    Author : Johan C Berglund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional correlation; functional surface; functional filtration; pressing die; multi-scale analysis; characterisation; finish milling; texture anisotropy; polishing; surface topography;

    Abstract : The manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. READ MORE

  6. 14. Optimizing surface texture for combustion engine cylinder liners

    Author : Andrew Spencer; Michel Cervantes; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The Piston Ring - Cylinder Liner (PRCL) contact is the single largest contributor to frictional losses in an internal combustion (IC) engine, causing 20-40% of all mechanical losses. If these mechanical losses can be reduced by 10% then vehicle fuel efficiency could be increased by approximately 1.5-2.5%. READ MORE

  7. 15. Calibration Procedure and Industrial Applications of Coherence Scanning Interferometer

    Author : Olena Flys; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coherence Scanning Interferometer; Power Spectral Density; 3D parameters; Characterization; uncertainty;

    Abstract : Countless industrial applications over the past decades have indicated the increased need to relate surface texture to surface function. Measurement and characterization of the areal nature of the surface allows the manufacturer to alter how the surface interacts with surroundings. READ MORE
