  1. 1. Tribological Aspects of Pneumatic Clutch Actuators

    Författare :Frida Riddar; Åsa Kassman Rudolphi; Roland Larsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear; friction; PTFE transfer; anodised aluminium; NBR rubber lip seal; silicone grease; casting; extrusion; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : A clutch actuator is used in a vehicle to transmit movement and force from the clutch pedal to the release bearing of the clutch. A pneumatic clutch actuator consists of an anodised aluminium cylinder, inside of which a piston, with a rubber lip seal and a PTFE guiding ring, slides. The system is lubricated with silicone grease before assembly. LÄS MER

  3. 2. Chemical reactions in aluminium electrolytic capacitors

    Författare :Ildiko Szaraz; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Sammanfattning : Aluminium electrolytic capacitors are used in a wide variety of different applications. The aluminium electrolytic capacitor consists of two aluminium foils wound together and separated by special paper, which is impregnated with an electrolyte. LÄS MER

  4. 3. Casting and anodising of Al alloys- Alloy design, manufacturing process and material properties

    Författare :Baiwei Zhu; Caterina Zanella; Rajan Ambat; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium; Semi-solid casting; Anodising; Gjutning av aluminium; semi-solid gjutning; anodisering; komponent; gjutlegering; kisel; järn;

    Sammanfattning : Casting and semi-solid metal (SSM) casting are widely used to manufacture near-net-shape components of Al-Si alloys in the automotive and electronic industries. In such applications, casting components need to meet the combined requirements of good mechanical properties and corrosion and wear resistance. LÄS MER

  5. 4. On the influence of Si on anodising and mechanical properties of cast aluminium alloys

    Författare :Baiwei Zhu; Caterina Zanella; Salem Seifeddine; Peter Leisner; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si based casting alloys; anodising; corrosion protection; mechanical properties; Al-Si-baserade gjutningslegeringar; anodisering; korrosionsskydd; mekaniska egenskaper;

    Sammanfattning : The combination of two cost-effective processes, i.e. casting and anodising, would be an interest for the aluminium component applications. However, there are some obstacles in the application of anodising on cast Al alloys. LÄS MER

  7. 5. Preparation and optical characterisation of antireflection coatingsand reflector materials for solar energy systems

    Författare :Per Nostell; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : An angle-resolved scatterometer and an integrating sphere for reflectance measurements at oblique angles of incidence have been designed and evaluated. The integrating sphere has a centre-mounted sample holder and the detector sits at the end of the sample holder and therefore always faces the same sphere wall area. LÄS MER
