4. 3. Micro-scale studies of wear

   Författare :Rickard Gåhlin; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Wear; micro-scale; methods; fundamental studies; AFM; micromechanical; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

   Sammanfattning : The development of materials for tribological components is constantly striving to more sophisticated properties, specialised for specific applications. This progress requires and depends to a large extent on a parallel development of the theoretical knowledge of wear and on development of the experimental tools for investigating wear in the research lab as well as in the field.
