  1. 11. Dielectric Response and Partial Discharge Characteristics of Stator Winding Insulation System with SiC Stress Grading

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Amar Abideen; [2020]
    Keywords : Stator Insulation; Dielectric Frequency Response; Polarization Depolarization Current; Insulation Modelling; FEM simulation;

    Abstract : The typical construction of a stator coil includes the use of end corona protection (ECP)coating, which is made of semi-conductive materials like silicon carbide (SiC). Thepurpose of ECP is to smooth the electric stress distribution near the slot exit, limitingthe electric field and partial discharge (PD) activity within the insulation system. READ MORE

  3. 12. Freeze-drying of protein pharmaceuticalin vials with different character

    University essay from Uppsala universitet/Institutionen för farmaci

    Author : Julia Falk; [2019]
    Keywords : ;

    Abstract : Freeze-drying of protein pharmaceuticals is a procedure frequentlyused to obtain stability of the active pharmaceutical ingredientduring distribution and storage. It can be performed in pre-filledsyringes, with a lubricous coating of silicone on the inside, toenable the piston moving. READ MORE

  4. 13. Modeling and Analysis of the Shot Peening Process : a Study of the Residual Stresses in an Insert using the Finite Element Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Hamid Torkaman; [2018]
    Keywords : Shot peening; Residual stresses; Cutting tool inserts; Post-coating treatment; Coated cemented carbide;

    Abstract : Cutting tool inserts are often coated with thin layers either through chemical vapor deposition (CVD) or physical vapor deposition (PVD) processes. In order to have a better wear resistance cutting tools are mostly subjected to post-coating treatment processes. READ MORE

  5. 14. Material characterization of multi-layered Zn-alloy coatings on fasteners : Effects on corrosion resistance, electrical conductivity and friction

    University essay from KTH/Materialvetenskap

    Author : Ante Vallien; [2018]
    Keywords : ZnNi; zinc alloy; multi-layered coating; electrodeposited coating; fasteners; corrosion resistance;

    Abstract : Electroplated zinc-alloy coatings have been used on fasteners in the automotive industry for many years. The coating often consists of three layers: a zinc-alloy layer, a passivation layer and a sealer or top-coat. READ MORE

  6. 15. MFC for paper surface treatment

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Yselaure Boissard; [2017]
    Keywords : microfibrillated cellulose; MFC; cellulose nanofibers; CNF; paper; coating; barrier;

    Abstract : In this study, microfibrillated cellulose (MFC) was applied in an aqueous suspension as a coating material on paper substrates. Two different coating techniques were used: rod coating and size press. READ MORE
