  2. 1. Antibacterial Strategies for Titanium Biomaterials

    Author : Erik Unosson; Ken Welch; Håkan Engqvist; Timo Närhi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium; silver; biomaterial; antibacterial; photocatalysis; hydrogen peroxide; reactive oxygen species; combinatorial materials science; Engineering Science with specialization in Materials Science; Teknisk fysik med inriktning mot materialvetenskap;

    Abstract : Titanium and titanium based alloys are widely used in dentistry and orthopedics to replace hard tissue and to mend broken bones. It has become a material of choice due to its low density, high strength, good biocompatibility and its capacity to integrate closely with the bone. READ MORE

  4. 2. Effect of Temperature on Mechanical Properties of Railway Wheel Steels

    Author : Nikas Dimitrios; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science; Materialvetenskap;

    Abstract : One of the most important aspects in railway operation is the interaction between rail and wheel. The contact conditions give rise to wear and damage in both components. Medium carbon steels are used in these components due to their combination of high strength and good wear properties in relation to cost. READ MORE

  5. 3. Weldability and Testing Methodology in Precipitation Hardening Superalloys

    Author : Jonny Jacobsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Weldability; Alloy 718; ATI® 718Plus™ and Haynes® 282®; Superalloys; Varestraint; Waspaloy®;

    Abstract : Usable weldability data is desired in the manufacturing industry, especially within the aerospace industry where fabrication of structural jet engine components are realized. Welding of precipitation hardening superalloys such as Waspaloy®, Alloy 718, ATI® 718Plus™ and Haynes® 282® in particular can lead to solidification cracking in the fusion zone, liquation cracking in the heat affected zone and/or to solid state cracking.

  6. 4. Holistic evaluation and testing of coil coatings

    Author : Alexander Wärnheim; C. Magnus Johnson; Per M. Claesson; Dan Persson; Carita Kvarnström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Anti-corrosion coatings; Coil coating; Weathering; FTIR; nano-FTIR; Hyperspectral imaging; AFM; Nanomechanical properties; korrosionsskyddsbeläggnignar; bandlackerade beläggningar; väderbeständighetstestning; FTIR; nano-FTIR; hyperspectral avbildning; Atomkraftsmikroskopi; nanomekaniska egenskaper; Kemi; Chemistry;

    Abstract : Coil coatings are durable  organic coatings used to protect metal sheets from corrosion and improve their aesthetic properties. Because of their extensive use, coil coatings have long been of interest for industrial and academic researchers. READ MORE

  7. 5. Surface Characterisation Using ToF-SIMS, AES and XPS of Silane Films and Organic Coatings Deposited on Metal Substrates

    Author : Ulf Bexell; Mikael Olsson; Sven Erik Hörnström; Åsa Kassman Rudolphi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Silanes; Organic films; ToF-SIMS; AES; XPS; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : This work focuses on the surface and interfacial characterisation of silane films of a non-organofunctional silane, 1,2-bis(triethoxysilyl)ethane (BTSE), and an organofunctional silane, γ-mercaptopropyltrimethoxysilane (γ-MPS), deposited on Al, Zn and Al-43.4Zn-1.6Si (AlZn) alloy coated steel.
