  1. 1. Understanding the effect of material composition and microstructure on the hot corrosion behaviour of plasma sprayed thermal barrier coatings

    University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Author : Ehsan Najafi; [2019]
    Keywords : Thermal barrier coatings; molten salt infiltration; TBC variations; hot corrosion test;

    Abstract : Thermal barrier coatings (TBC) are used in the hot sections of gas turbine engine in order to insulate the substrate at high temperature. Molten salt infiltration retards the durability of TBCs. The current standard material, i.e. READ MORE

  2. 2. Plasmin and plasminogen variation in bovine raw milk : impact of season, breed and milking system

    University essay from SLU/Department of Molecular Sciences

    Author : Jaafar Khaled; [2019]
    Keywords : Plasmin; season; breed; milking system; milk composition; plasminogen;

    Abstract : Plasmin (PL) is a native proteinase in milk, which combines a complex system consisting of its zymogen called plasminogen (PG), inhibitors and activators, which activity is known to make considerable changes in the dairy products, which represent in irregulating of casein hydrolysis and poor clotting properties, that may slow the cheese ripening process and consequently increase the processing expense. The objective of this study was to investigate if on-farm factors (i. READ MORE

  3. 3. Failure analysis of suspension plasma sprayed thermal barrier coatings

    University essay from Högskolan Väst/Forskningsmiljön produktionsteknik(PTW)

    Author : Mohammed Jasim; [2017]
    Keywords : Failure analysis; Suspension plasma sprayed; Thermal barrier coating;

    Abstract : Thermal barrier coatings (TBC) are proven to protect the hot section of components operated under elevated temperature. Suspension Plasma Spray (SPS) is an emerging manufacturing process that is used to produce TBCsI, It has the ability to deposit a thinner TBC that has finer microstructure than coatings deposited using traditional Atmospheric Plasma Spray (APS).

  4. 4. Measurement of Thermal Insulation properties of TBC inside the Combustion chamber

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Siamak Kianzad; [2017]
    Keywords : Materials; TBC; Thermal barrier coating; heat flux; crack; combustion chamber; heavy duty diesel engine; single-cylinder; dummy valve; 8YSZ; YSZ; segmented cracks; radiative heat transfer; lanthanum gadolinium; EB-PVD; PVD; APS; CVD; horizontal cracks; vertical cracks; crack propagation; crack initiation;

    Abstract : This master thesis project was performed in collaboration with Scania CV AB, Engine Materials group. The purpose with the project was to investigate different ceramic TBC (Thermal Barrier Coating) thermal insulation properties inside the combustion chamber. READ MORE

  5. 5. A Study on Timed Base Choice Criteria for Testing Embedded Software

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Henning Bergström; [2016]
    Keywords : test; base choice; time; coverage criteria; embedded; plc;

    Abstract : Programs for Programmable Logic Controller (PLC) are often written in graphical or textual languages. Control engineers design and use them in systems where safety is vital, such as avionics, nuclear power plants or transportation systems. READ MORE
