  5. 13. Gear tribology : friction and surface topography

    Author : Li Xiao; Bengt-Göran Rosén; Liam Blunt; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; Surface topography; Toughness; Lay; Gears; Power transmission; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The quest for energy efficiency leads to the development of highly efficient power transmissions for vehicles. Gears are some of the most rugged and durable torque transmitters among machine elements. Friction between sliding surfaces at gear teeth is one major source of power loss. READ MORE

  6. 14. Toughness Enhancement in Hard Single-Crystal Transition-Metal Nitrides : V-Mo-N and V-W-N Alloys

    Author : Hanna Kindlund; Lars Hultman; Jens Birch; Daniel Gall; Linköpings universitet; []
    Keywords : ;

    Abstract : Transition-metal nitrides are known for their high hardness, good wear resistance, high-temperature stability, and chemical inertness. Because of these properties, they are extensively used in many industrial applications, notably as protective wear, erosion, and scratch resistant coatings, which are often subjected to high thermo-mechanical stresses.

  7. 15. Chemical Methods for Improving the Fracture Toughness of Paper

    Author : Andrew T. Horvath; Lars Wågberg; Theo van de Ven; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemistry; physical chemistry; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Paper is a network material composed of a great number of fibers that interact with each other through fiber joints. In order to make a clear statement regarding observed changes being made in paper, it is vital to determine the structural level of paper that is being affected by chemical modifications. READ MORE
