  2. 1. High Temperature Corrosion Behavior in Biomass- and Waste-Fired Boilers - Insights into catastrophic corrosion and corrosion mitigation techniques

    Author : Julien Phother Simon; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D tomography; TEM; Sulfur Recirculation; Waste; High-temperature corrosion; Biomass; Coatings; Stainless steel; Ni-based alloys; Deposits; KCl-induced corrosion;

    Abstract : Carbon dioxide is contributing to the greenhouse effect and a significant part comes from the use of fossil fuels. Utilizing more renewable fuels is therefore a solution to decrease the net release of CO2 emissions to the atmosphere. READ MORE

  4. 2. Corrosion of ferritic stainless steels used in solid oxide fuel cells - Investigation of novel coatings in single- and dual-atmosphere conditions

    Author : Matthieu Tomas; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Copper; Interconnect; Coatings; Alumina; Dual Atmosphere; Area-Specific Resistance; SOFC; Corrosion;

    Abstract : Solid Oxide Fuel Cells (SOFCs) are systems that convert chemical energy into electrical energy. Their high electrical efficiency and clean emissions (when H2 is used as fuel) make them a strong candidate for replacing conventional conversion systems, such as combustion engines. READ MORE

  5. 3. Designing multicomponent alloy coatings for corrosion protection

    Author : León Zendejas Medina; Ulf Jansson; Leif Nyholm; Zoe Barber; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; corrosion; thin films; coatings; magnetron sputtering; high entropy alloy; percolation theory; mechanical tests; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : This thesis explores the design of metallic coatings for corrosion protection. The subject of the study was the new class of materials multicomponent alloys (MCAs, also known as high entropy alloys). They consist of near-equal concentrations of many (four or more) metals and are often reported to form a single phase with a simple crystal structure. READ MORE

  6. 4. High Temperature Corrosion of FeCrAl Alloys in Biomass- and Waste-fired Boilers - The Influence of Alloying Elements in Prediction and Mitigation of Corrosion in Harsh Environments

    Abstract : Combustion of biomass and waste for heat and power production is an alternative to fossil fuels and can be an important step towards a more sustainable future. The electrical efficiency of the fuel-to-energy conversion process is largely dependent on the steam parameters (temperature and pressure) of the combined heat and power (CHP) plants. READ MORE

  7. 5. Thermal Barrier Coatings : Failure Mechanisms and Life Prediction

    Author : Krishna Praveen Jonnalagadda; Ru Lin Peng; Xin-Hai Li; Robert Eriksson; Nicholls John; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. READ MORE
