  1. 1. Development of titanium-copper alloys for dental applications

    Författare :Lee Fowler; Caroline Öhman-Mägi; Håkan Engqvist; Susanne Norgren; Eduard Hryha; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium; copper; antibacterial; Ti2Cu; biomaterials; Staphylococcus epidermidis; MC3T3 cells;

    Sammanfattning : Titanium alloys find wide application in the medical implants industry, which includes areas of orthopaedic and dental implants. The reason for the popularity of the material is high mechanical strength, low density, and reported growth of bone onto the material, as well as corrosion resistance. LÄS MER

  3. 2. Concepts for hot sheet metal forming of titanium alloys

    Sammanfattning : To increase the competitiveness of the Swedish aero engine industry alternative manufacturing methods for load carrying aero engine structures are desired, in order to reduce product cost and enable weight reduction and thereby fuel consumption. Traditionally, these structures mainly consist of large-scaled single castings of e.g. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Sammanfattning : Titanium alloys were for a time believed to be highly resistant to environmentally assisted cracking because of their ability to form a protective oxide film on the surface. Their resistance can still be considered to be high, but when cracking resistance was originally defined to ensure reliable functionality of fracture-critical components, certain conditions that promote cracking were discovered.
