  1. 1. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Muhammad Hashir Zaheer; [2023]
    Keywords : High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

    Abstract : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. READ MORE

  3. 2. Atomic wear mechanisms of hard chrome against Al2O3

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

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

    Abstract : 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. READ MORE

  4. 3. Tribological characterisation of additively manufactured hot forming steels

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Anna Vikhareva; [2020]
    Keywords : High temperature tribology; additive manufacturing; hot stamping; maraging steel; H13; galling;

    Abstract : Over the last decade, the application of ultra-high strength steel as safety components and structural reinforcements in automobile applications has increased due to their favourable high-strength-to-weight ratio. The complex shaped components are widely produced using hot stamping. READ MORE

  5. 4. Bekämpning av rotgallnematodarterna Meloidogyne hapla, M. chitwoodi och M. fallax : grödors naturliga resistens som alternativ till svartträda?

    University essay from SLU/Dept. of Ecology

    Author : Jesper Fritzson; [2020]
    Keywords : rotgallnematoder; naturlig resistens; fånggröda; bekämpning; oljerättika; tagetes;

    Abstract : Växtparasitära nematoder börjar bli ett allt större problem världen över där de orsakar stora ekonomiska skador. Bekämpningen av dessa blir svårare allt eftersom kemiska bekämpningsmedel mot nematoder mer och mer globalt förbjuds på grund av dess toxiska påverkan på bland annat applicerande lantbrukare samt ekosystem runtom och i nematodinfekterade fält.

  6. 5. High Temperature Tribology in Hot Stamping

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Evan Kurnia; [2019]
    Keywords : high temperature tribology; hot stamping; acoustic emission; condition monitoring; hardfacing;

    Abstract : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. READ MORE
