    Sammanfattning : Laser beam welding has gained a significant interest during the last two decades. The suitability of the process for high volume production has the possibility to give a strong advantage compared to several other welding methods. However, it is important to have the process in full control since various quality issues may otherwise occur. LÄS MER

  2. 37. Conformal chemical vapor deposition of boron carbide thin films

    Författare :Arun Haridas Choolakkal; Jens Birch; Henrik Pedersen; Hans Högberg; Tobias Törndahl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The sustainability goals of the modern world and the fascinating properties of sub-micron scale materials promote development of materials in thin film form. Thin films are materials that have thicknesses ranging from sub-nanometer to several micrometers, synthesized by various deposition techniques. LÄS MER
