    Sammanfattning : Microengineering has developed a broad range of production techniques to reduce size, increase throughput, and reduce cost of electrical and mechanical devices. The miniaturisation has also entailed entirely new opportunities. LÄS MER

  3. 2. Microengineering of diamond

    Författare :Henrik Björkman; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : Performance of micromechanical systems often relies on extreme material properties. Being the strongest, stiffest and hardest of all materials, exhibiting extreme electromagnetic transparency and wear resistance, and offering the highest possible thermal conductivity and very low friction against most materials, diamond is indeed a unique material.

  4. 3. Microengineered CVD Diamond Surfaces : Tribology and Applications

    Författare :Joakim Andersson; Staffan Jacobson; Arto Alahelisten; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Diamond; DLC; Tribology; Friction; Environment; Microengineering; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Recent developments in thin film synthesis of diamond have facilitated a host of new technical applications. These are motivated by the many attractive properties of diamond, for example high hardness, chemical inertness, transparency and heat conductivity. Unfortunately, these properties also make it difficult to fashion complex geometries. LÄS MER
