    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Clarence Wahman; [2021]
    Keywords : Mangesium; WE43; corrosion; additive manufacturing; biodegradable implants; microstructure; surface roughness; Magnesium; WE43; korrosion; additiv tillverkning; resorberbara implantat; mikrostruktur; ytråhet;

    Abstract : The work presented in this thesis was conducted at Uppsala University and at Swerim AB. The study aims to broaden the knowledge about the corrosion of additively manufactured bioresorbable alloy WE43 in humanlike conditions for future applications. READ MORE

  3. 2. Factors governing marble lightness in peripheral alteration haloes around carbonate-hosted Zn-Pb-Ag-(Cu-Au) deposits, Garpenberg, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Marcus Eriksson; [2020]
    Keywords : Carbonate; Zn; Pb; Ag; Cu; Au; Alteration haloes; marble; lightness; Bergslagen; Garpenberg;

    Abstract : A Master thesis about the Garpenberg deposit located in Bergslagen, a lithotectonic domain, with a mining history that might date back as far as 350 BC. Marble- and skarn-hosted sulfide deposits are found in the area, which creates the opportunity to mine both limestone and sulfidic ore in a single mine. READ MORE

  4. 3. Application of some modern analytical techniques for investigations of non-metallic inclusions in steel samples

    University essay from KTH/Materialvetenskap

    Author : Wan Zhiyue; [2018]
    Keywords : Non-metallic Inclusions; Electrolytic Extraction; Fractional Gas Analysis; Zirconium Addition; Calcium Treatment;

    Abstract : The non-metallic inclusions (NMI) have large influence on steel properties. Therefore, evaluation of inclusion size, number, composition and morphology by using modern analytical techniques are very important for control of steel production and steel quality. Three dimensional analysis method of electrolytic extraction is applied in this work. READ MORE

  5. 4. Investigation of the possibility for using ZrO2 and ZrSiO4 for Zr additions to liquid ferrosilicon

    University essay from KTH/Materialvetenskap

    Author : Amanda Vickerfält; [2017]
    Keywords : inoculant; ferrosilicon; zirconium; zirconia; zircon sand;

    Abstract : Ferrosilicon containing 50-75% Si and 1.0-5.0% Zr is used as inoculant in the cast iron industry. Zr can be added to liquid ferrosilicon by use of Zr metal or zirconium ferroalloy (FeSiZr). READ MORE

  6. 5. 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)).
