    Sammanfattning : In this thesis nanocomposite materials for use in high performance electrical contacts are tested. Self mating silver as coatings on cupper substrates are the most used material combination in power connectors today. In this work two new concepts were tested. LÄS MER

  2. 2. Me-Si-C (Me= Nb, Ti or Zr) : Nanocomposite and Amorphous Thin Films

    Författare :Olof Tengstrand; Lars Hultman; Per Eklund; Benny André; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis investigates thin films of the transition metal carbide systems Ti-Si-C, Nb-Si-C, and Zr-Si-C, deposited at a low substrate temperature (350 °C) with dc magnetron sputtering in an Ar discharge. Both the electrical and mechanical properties of these systems are highly affected by their structure. LÄS MER
