  1. 16. Tribological behaviour of CVD diamondcoated tools during machining of highstrength aluminum alloy : Master thesis project on tribological behavior of super hard materials: chemicalvapor deposition diamond (CVD) coated cutting tools and polycrystalline diamond(PCD) cutting tools used in machining of high strength aluminium alloy

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Oskar Lundquist; [2022]
    Nyckelord :CVD diamond coating; CVD; Aluminum machining; Tool coatings; PCD; diamond coating; diamond; Tribology; Material Science.;

    Sammanfattning : Machining of Aluminum can be complicated due to large amounts of adhesion and diffusion of the aluminum onto the cutting tool, causing effects such as built-up layers and built-up edges. This leads to poor surface finishes and can significantly affect the tool life. LÄS MER

  3. 17. Evaluation of long-term effects of excavated sulfide-bearing rock : - A case study in western Sweden

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Ida Sundblom; [2022]
    Nyckelord :sulfide-bearing rock; acid rock drainage; sulfide oxidation;

    Sammanfattning : Sulfide-bearing rock that is excavated in conjunction with construction projects can cause environmental and construction engineering problems. Sulfidic minerals oxidize when they are exposed to an oxidant and water, which can make them generate acid rock drainage (ARD) with high concentrations of metals and sulphate. LÄS MER

  4. 18. Developing a Parameterized Embodied Emissions Calculator for telecommunication networks equipment (PEEC)

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Maël Madon; [2021]
    Nyckelord :;

    Sammanfattning : Temperature on the surface of the earth has already increased by 1°C above pre-industriallevels. To have a chance to keep global warming under 1,5°C, greenhouse gas emissions fromhuman activities should be halved by 2030, reaching net zero in 2050. Every business sectoris concerned. LÄS MER

  5. 19. Atomic wear mechanisms of hard chrome against Al2O3

    M1-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Raul Fierro Tobar; Marius Yuku; [2021]
    Nyckelord :Wear mechanisms; DFT; MD; hard chrome; aluminium; RDF; adhesive; abrasive; Nötning; DFT; MD; hårdkrom; aluminium; RDF; adhesiv; abrasiv;

    Sammanfattning : Hard chrome exhibit hardness of about 70 HRC and lubricity that prevents seizing and galling and is therefore the common first choice for engineers to reduce friction and minimize wear. These properties enable engineering applications such as cutting and drilling, especially in manufacturing, production and consumer good industries. LÄS MER

  7. 20. Laser ablation of aluminium before welding : Effect of weld preparation on number and sizes of pores

    Uppsats för yrkesexamina på avancerad nivå, KTH/Materialvetenskap

    Författare :Olivia Taivalkoski; [2021]
    Nyckelord :;

    Sammanfattning : Welding aluminium often results in porosity in the weld. One way to reduce porosity is by carful weld preparation and cleaning. In this master thesis report laser ablation was done on aluminium plates before welding to remove dirt and the surface oxide layer. LÄS MER
