1. 1. Form and Finish of Implants in Uncemented Hip Arthroplasty : Effects of Different Shapes and Surface Treatments on Implant Stability

   Författare :Stergios Lazarinis; Nils P. Hailer; Lars Weidenhielm; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Form; Finish; Total hip arthroplasty; Swedish Hip Arthroplasty Register; Hydroxyapatite; RSA; DXA; BMD; Stability.; Orthopaedics; Ortopedi;

   Sammanfattning : The design of an uncemented hip arthroplasty implant affects its long-term survival. Characteristics such as the form and the finish of the implant are crucial in order to achieve the best possible conditions for long-term implant survival. LÄS MER

3. 2. Methods for Characterisation of Pressing Die Surfaces

   Författare :Johan C Berglund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finish milling; scale-sensitive fractal analysis; surface characterisation; polishing; functional correlation; : pressing dies; functional filtration; surface roughness; functional surface;

   Sammanfattning : Design and manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. LÄS MER

4. 3. On Transfer of Work Material to Tools

   Författare :Jannica Heinrichs; Staffan Jacobson; Urban Wiklund; Uppsala universitet; []
   Nyckelord :Tribology; Friction; Forming; Cutting; Galling; Material transfer; Tribological coatings; Surface finish; Micro mechanisms; Aluminium; Materialvetenskap; Materials Science;

   Sammanfattning : Bulk forming and cutting are widely used to shape metals in industrial production. Bulk forming is characterized by large strains, extensive plastic deformation and large surface expansions. Cutting is characterized by high speeds, high pressures and high temperatures. LÄS MER

5. 4. Electrochemical machining: towards 3D simulation and application on SS316

   Författare :A. A. Gomez-Gallegos; UK University of Edinburgh; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochemical machining; 3D Simulation; FEM; stainless Steel 316; surface Finish; Maskinteknik; Mechanical Engineering;

   Sammanfattning : Electrochemical machining (ECM) is a non-conventional manufacturing process, which uses electrochemical dissolution to shape any conductive metal regardless of its mechanical properties and without leaving behind residual stresses or tool wear. Therefore, ECM can be an alternative for machining difficult-to-cut materials, complex geometries, and materials with improved characteristics, such as strength, heat-resistance or corrosion-resistance.
