  4. 2. Mechanical Characterisation of Coatings and Composites-Depth-Sensing Indentation and Finite Element Modelling

    Author : Zhi-Hui Xu; KTH; []
    Keywords : dept-sensing indentation; nanoindentation; finite element method; atomic force microscope;

    Abstract : In the past two decades depth-sensing indentation has becomea widely used technique to measure the mechanical properties ofmaterials. This technique is particularly suitable for thecharacterisation of materials at sub-micro or nano scale thoughthere is a tendency to extend its application to the micro ormacro scale. READ MORE

  5. 3. High-performance Load-bearing Alloys

    Author : Guo-Hua Zhao; Annika Borgenstam; Konstantinos Georgarakis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The aim of this thesis is to study advanced metallic alloys as load-bearing componentsfor engineering and biomedical applications. The investigations have been focusing onthe improvement of the properties and performance of existing materials as well assynthesizing and developing completely new materials. READ MORE

  6. 4. Friction in Elastohydrodynamic Lubrication

    Author : Marcus Björling; H. P. Evans; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Today, with increasing demands on industry to reduce energy consumption and emissions, the strive to increase the efficiency of machine components is maybe bigger than ever. This PhD thesis focus on friction in elastohydrodynamic lubrication (EHL), found in, among others, gears, bearings and cam followers. READ MORE

  7. 5. Microengineered CVD Diamond Surfaces : Tribology and Applications

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

    Abstract : 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. READ MORE
