  3. 2. Synthesis, Characterization, and Evaluation of Ag-based Electrical Contact Materials

    Författare :Fang Mao; Ulf Jansson; Mikael Olsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrical contact; bulk; coating; Ag-based alloys; Ag-based delafossite; AgI; graphene; graphene oxide; combinatorial material science; dc magnetron sputtering; friction; wear; hardness; contact resistance;

    Sammanfattning : Ag is a widely used electrical contact material due to its excellent electrical properties. The problems with Ag are that it is soft and has poor tribological properties (high friction and wear in Ag/Ag sliding contacts). LÄS MER

    Sammanfattning : For many years, Sweden has had a reputation for having a comprehensive and women friendly welfare state. However, as in many other European countries during the past few decades, the organization and governing of welfare has undergone profound changes. LÄS MER

  5. 4. Readiness or resistance? : Newly arrived adult migrants' experiences, meaning making, and learning in Sweden

    Författare :Afrah Abdulla; Lisbeth Eriksson; Signild Risenfors; Hans-Erik Hermansson; Linköpings universitet; []

    Sammanfattning : This thesis is about newly arrived adult migrants’ meaning making and learning in Swedish society during the two years’ introduction period, after they have received the residence permit. I have specifically studied Arabic speaking adults’ meaning making and learning, by carrying out observations and individual in-depth interviews with 12 migrants. LÄS MER

  7. 5. A study on contact fatigue mechanisms

    Författare :Bo Alfredsson; KTH; []
    Nyckelord :contact fatigue mechanism; spall; spalling; surface crakc; sub-surface crack; elesto-plastic indentation; contact compliance measurement; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Surfaces subjected to rolling and sliding contacts maysuffer from contact fatigue. This thesisdeals with solidmechanic aspects of contact fatigue including the descriptionand verificationof explaining mechanisms. The new mechanism forsurface initiated contact fatigue is basedon tensile surfacestresses from local asperity contacts. LÄS MER
