  1. 1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

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

    Author : Ahsan Ali; [2023]
    Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

  3. 2. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kaibin Wen; [2023]
    Keywords : Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

    Abstract : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. READ MORE

  4. 3. Påverkas totalproteinnivåer i blodprov från kalvar av att blodprovet inte centrifugeras samt av hemolys?

    University essay from SLU/Dept. of Clinical Sciences

    Author : Linn Ambjörnsson; [2023]
    Keywords : råmjölk; refraktometer; blodprov; kalvhälsa; Brix;

    Abstract : Råmjölken innehåller livsviktiga antikroppar som ger kalven dess immunförsvar under de första månaderna i livet. För att kontrollera att kalven fått i sig en tillräcklig mängd antikroppar tas ett blodprov och detta serum analyseras med avseende på antikroppar. READ MORE

  5. 4. Experimental Investigation of High Prandtl Number Flow in Additive Manufactured Channels

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : LINDA YANG; [2023]
    Keywords : Additive manufacturing; Heat transfer; Darcy friction factor; Nusselt number; Minichannel.; Friformsframställning; Värmeöverföring; Darcy friction factor; Nusselt number; Minikanal.;

    Abstract : Additive manufacturing (AM) rapidly evolves and expands into new industries dueto its great design freedom and time savings. Injection molding is an excellentindustry where AM can help reduce cooling time by printing complex coolingchannels for more effective and uniform cooling. READ MORE

  6. 5. Model-Observation Comparisons of O+ Concentrations in the Martian Ionosphere

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Chinmaya Nagar; [2023]
    Keywords : MAVEN; NGIMS; Martian; Ionosphere; Fehsenfeld; Tenewitz;

    Abstract : A few years ago, the charge-transfer reaction CO2+  +  O ⟶ O+ + CO2 was investigated experimentally for the first time since the study by Fehsenfeld et al., (1970). This new investigation was conducted by Tenewitz et al., (2018). READ MORE
