1. 1. Erosion Behaviour of Thermal Barrier Coatings

   University essay from Linköpings universitet/Konstruktionsmaterial

   Author : Caroline Wännman; [2021]
   Keywords : erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

   Abstract : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. READ MORE

3. 2. Total bacterial count as an attribute for raw milk quality

   University essay from SLU/Department of Molecular Sciences

   Author : Helena Markusson; [2021]
   Keywords : total bacterial count; milk microbiota; raw milk quality; spoilage;

   Abstract : Milk is a nutritious food and at the same time a substrate where microorganisms thrive. Their metabolic impact can be useful in dairy fermentation, but the degradation of compounds within its habitat can also cause dairy food spoilage. READ MORE

4. 3. 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

5. 4. 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

6. 5. 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).
