  1. 6. Surface Studies on Industrial Aluminium Alloys

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Lisa Rullik; [2014]
    Keywords : aluminium alloy; heat treatment; XPS; XPEEM; Physics and Astronomy;

    Abstract : Aluminium alloys are used in a wide range of applications due to their high tensile strength concomitant with low density. Additionally, aluminium alloys form a naturally occurring and passivating oxide layer, which leads to high corrosion and weathering resistance. READ MORE

  2. 7. New concept for the ground connection in Scania’s trucks and buses

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : ANDRÉS LLORENTE; [2014]
    Keywords : Electrical Contacts; Heavy-duty vehicles; Grounding; SRM Stud welding;

    Abstract : Regarding the ground electrical connection in trucks and buses, the requirements of earthing in heavy-duty vehicles were gathered and evaluated. The most important problems in the state-of-the-art grounding devices are corrosion, electrical resistance and uncertainty in the mounting process, altogether with depreciation over time. READ MORE

  3. 8. A calorimetric analysis and solid-solubility examination of aluminium alloys containing low-melting-point elements

    University essay from KTH/Materialvetenskap

    Author : Niclas Ånmark; [2012]
    Keywords : differential scanning calorimetry; calibration; braze clad fin material; heat exchanger; aluminium; heating rate; solid-solubility; trace elements; melting range;

    Abstract : The formation of liquid films is a widely known problem in aluminium heat exchanger materials. The phenomenon results in decreased brazeability along with severely deteriorated mechanical properties which might cause assembly collapse. READ MORE

  4. 9. Erosion during Brazing in Stainless Steel grade 304

    University essay from KTH/Materialvetenskap

    Author : Nabeel jahanzeb; [2012]
    Keywords : Erosion; dissolution of base; filler metal; Wettability; oxygen partial pressure; high vacuum; SEM analysis.;

    Abstract : The erosion or dissolution of stainless steel grade 304 as base metal by molten brazing fillermetal was investigated using one nickel and two iron based filler metals. The difference betweentwo iron filler metal is 5 % Manganese content in one of the filler metal. READ MORE

  5. 10. MIG/MAG brazing with Cold Metal Transfer

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : MARIE ALLVAR; [2012]
    Keywords : CMT; Cold Metal Transfer; forceTIG; Plasmatron; brazing; arc brazing; laser brazing; automotive; zinc coated; galvanised; lap joint; CMT; Cold Metal Transfer; forceTIG; Plasmatron; lödning; båglödning; laserlödning; fordonsindustri; förzinkad; överlappsfog;

    Abstract : In the automotive industry a commonly used material is thin steel sheets coated with a thin layer of zinc for corrosion resistance purposes. Welding of this material, with the high temperatures involved, causes problems with zinc burn-off leading to reduced corrosion resistance. READ MORE
