  2. 1. Electrical and Frictional Performance of Tin-Coated Contacts Exposed to Wear and Fretting Corrosion

    Author : Tag Hammam; Åke Öberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Friction; Fretting; Wear; Contact resistance; Tin; Connectors; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : The complexity of electronic systems in vehicles is rapidly increasing, and as a consequence, the long-term reliability of automotive connectors has become an important issue. The aims of this thesis have been: 1. to characterize the friction, wear and electrical properties of tin coatings, 2. READ MORE

  4. 2. Surface Technology for Optical and Electrical Connectors

    Author : Niklas Gunnarsson Sarius; Lars Hultman; Peter Leisner; Klas Hjort; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis treats surface engineering with the purpose of improved quality of optical and electricalconnectors with a focus on electroplated and magnetron sputtered materials. In electroforming of tools formanufacturing optical connectors, the influence of ultrasonic agitation on intrinsic stresses and fillingproperties of electroplated Ni has been studied. READ MORE

  6. 4. Composite Bridges : Innovative ways of achieving composite action

    Author : Robert Hällmark; Peter Collin; Ian May; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite action; bridges; steel; concrete; shear connectors; prefabrication; coiled spring pins; shear studs; post-installation; design guidance; Structural Engineering; Konstruktionsteknik;

    Abstract : The topic of this thesis is steel-concrete composite bridges and innovative ways of achieving composite action. The typical superstructure consists of three main components: the steel girders, the concrete deck slab and the shear connectors. READ MORE

  7. 5. Development of prefabricated timber-concrete composite floors

    Author : Elzbieta Lukaszewska; Hans-Joachim Blass; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : Timber-concrete composite structures were originally developed for bridges and upgrading of existing timber floors, but finds today new applications in multi-storey buildings. Most of the research performed to date has been focused on systems where "wet" concrete is cast on top of timber beams with mounted connectors. READ MORE
