  1. 6. U-Pb geochronology and geochemistry of host rocks to the Bastnäs-type REE mineralization in the Riddarhyttan area, west central Bergslagen, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Wictor Linders; [2016]
    Keywords : Riddarhyttan; REE; Metavolcanic rocks; LA-ICP-MS; Zircon; Monazite.; Earth and Environmental Sciences;

    Abstract : The geochronology of felsic metavolcanic rocks hosting the Bastnäs-type rare earth element (REE) mineralization in the Riddarhyttan area in the Bergslagen region, Sweden, was investigated using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) U-Th-Pb on zircon and monazite. U-Pb data from four host rock samples yield dates of 1899 ± 4 Ma (MSWD=2. READ MORE

  3. 7. Deposition of Zr(C,N) Coatings by Chemical Vapour Deposition

    University essay from KTH/Materialvetenskap

    Author : Linn Efsing; [2015]
    Keywords : Zr C; N ; MTCVD; Milling inserts; Coating; Growth rate; Microstructure; Texture coefficients;

    Abstract : In this master thesis the influence from process parameters within the Chemical vapour deposition process for a Zirconium Carbon-Nitride coating was investigated regarding growth rate, microstructure and texture. The interest in utilizing Zirconium Carbon-Nitride (Zr(C,N)) is due to its low coefficient of thermal expansion (CTE) relative the currently commonly used wear resistant coatings of Titanium-Carbon-Nitride (Ti(C,N)).

  4. 8. CALPHAD study of cubic carbide systems with Cr

    University essay from KTH/Materialvetenskap

    Author : Zhangting He; [2015]
    Keywords : CALPHAD; cubic carbide; thermodynamics;

    Abstract : Cubic carbides (titanium, tantalum, niobium, and zirconium carbides) can constitute a significant proportion of so-called cubic and cermet grades, where it is added to substitute a portion of tungsten carbide. It is thus critical to understand and be able to thermodynamically model the cubic carbide systems. READ MORE

  5. 9. Production, Characterization and Electrochemical Properties of Advanced Bulk Metallic Glasses for Hip Implant Applications

    University essay from KTH/Materialens processvetenskap

    Author : Ali Tabeshian; [2011]
    Keywords : Biomaterials; Bulk Metallic Glass; Crystalline Zr55Cu30Ni5Al10; Co-Cr-Mo alloy; Stainless steel; Polarization curve; FTIR; Impedance.;

    Abstract : The aim of the present project was to investigate the possibilities of using a Zr55Cu30Ni5Al10 Bulk Metallic Glass (BMG) alloy as articulating surface in an artificial hip joint. In order for a material to be used in human body as an implant, the foremost requirement is the acceptability by the human body. READ MORE

  6. 10. Petrology and lithogeochemistry of the host rocks to the Nautanen Cu-Au deposit, Gällivare area, northern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Ian McGimpsey; [2010]
    Keywords : geography; geology; petrology; lithogeochemistry; Nautanen Cu-Au deposit; Gällivare; northern Sweden; Earth and Environmental Sciences;

    Abstract : The Nautanen Cu-Au deposit is located 75 km north of the Arctic circle, and 10 km northeast of the town of Gällivare in northern Sweden. Nautanen is just 8 km west of the giant Malmberget apatite-iron ore deposit and 15 km north of one of Europe’s largest copper producers, the Aitik Cu (Au) porphyry deposit. READ MORE
