Pitting Corrosion of Super Duplex Stainless Steel - Effect of Tungsten and Isothermal Heat Treatments
(Master thesis, 2017)Duplex stainless steels (DSS) and super duplex stainless steels (SDSS) can be described as austenitic-ferritic stainless steels with a chromium content of 22 and 25 %, respectively. Because of their good combination of ... -
Preparation of (La0.8Sr0.2)0.995CoO3-based Inks for Ink-Jet Printing of Thin Films in Solid Oxide Fuel Cells (SOFCs)
(Master thesis, 2017)Lanthanum Strontium Cobalt oxide (LSC) is a mixed ionic-electronic conductor (MIEC) ceramic suited for use as cathode material in Solid Oxide Fuel Cells (SOFCs). Extensive research is conducted on producing the cathode in ... -
Study of Piezoelectric and Mechanical Properties of Porous Barium Titanate Ceramics for Biomedical Applications
(Master thesis, 2017)Throughout the last decades, the development of bioactive materials to be used as bone implants has been a very active research area. The number of surgeries related to bone implants are steadily increasing, such that ... -
Surface treatment of high performance multicrystalline silicon wafers
(Master thesis, 2018)This master thesis investigates the properties of high performance multicrystalline silicon, and the production line of black multicrystalline silicon solar cells with PERC architecture. Possible solutions to achieve ... -
Tapping of FeSi Furnaces
(Master thesis, 2018)Ferrosilicon is usually produced in an electric arc furnace. During the tapping of the furnace solidification of FeSi and slag in the runner and ladle are a major issue because it lowers the ferrosilicon yield and causes ... -
The Effect of Hydrogen on the Corrosion Resistance of Stainless Steel in Seawater
(Master thesis, 2018)Stainless steels have been used for various applications in the oil and gas industry for a long time due to, among others, their high corrosion resistance. However, immersion in seawater is demanding of the material because ... -
The Properties of Calcined Anthracite
(Master thesis, 2017)The aim of this thesis has been to look at the thermal behaviour of anthracite, coke and charcoal regarding their expansion during heating and their release of off-gases. Furthermore, to look at how the porosity and expansion ... -
The relation between microstructure and thermoelectric properties in Ta-substituted A-site deficient CaMnO3
(Master thesis, 2017)Calcium manganite, CaMnO3, is an n-type semiconductor with promising thermoelectric (TE) properties. However, for commercial applications the performance of the material, described by the thermoelectric figure of merit ... -
Vapour Pressure of Bi above Bi-Ti Alloys by Transpiration Method
(Master thesis, 2017)Titanium is an attractive metal with wide-ranging applications due to its properties. Titanium is one of the most corrosion resistant metals with the highest strength-to-weight ratio. The only industrial production route ...
