  1. 31. Cathodic arc deposition of metal-rich Cr-based coatings

    Författare :Johan Nyman; Hans Högberg; Jens Birch; Niklas Sarius; Muhammad Junaid; Nina Schalk; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cathodic arc deposition; Cr coatings; Metal-rich; Cr-N; Cr-C;

    Sammanfattning : Wood and wood-based products have always been key components in the development of human civilization. Nowadays most wood harvesting is done using chainsaws, and their efficient operation helps promote worker safety and reduce emissions. LÄS MER

  3. 32. Colour-changing textile coatings containing multi-layered mica pigments : an experimental study

    Författare :Veronica Malm; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mulit-layered mica pigment; effect pigments; angle-dependent color-changes; textile coatings; surface structure; rheology modifiers; coating parameters; Textile Technology; Textiles and Fashion General ; Textil och mode generell ;

    Sammanfattning : This study investigates the possibility of producing angle-dependent colour-changing textiles with thickened polyurethane (PU)-based aqueous dispersion containing multi-layered mica pigments using a direct coating method. Colour changing textile coatings with the latest generation of layered mica pigment (EP) have a promising future for functional purposes such as authentication and aesthetic eye-catching applications.

  4. 33. Low Cycle Fatigue and Thermo-Mechanical Fatigue of Uncoated and Coated Nickel-Base Superalloys

    Författare :Svjetlana Stekovic; Torsten Ericsson; Hael Mughrabi; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AMDRY997; CMSX-4; SCB; Thermo-Mechanical Fatigue; Coatings; Gas Turbine; IC1; IC3; IN792; Low Cycle Fatigue; Nickel-Base Superalloys; RT22; Materials science; Teknisk materialvetenskap;

    Sammanfattning : High strength nickel-base superalloys have been used in turbine blades for many years because of their superior performance at high temperatures. In such environments superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface. LÄS MER

  5. 34. Design of Thermal Barrier Coatings

    Författare :Nicholas Curry; Nicolaie Markocsan; Per Nylén; Matthias Oechsner; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Gas Turbine; Aero Turbine; Thermal Barrier Coating; Atmospheric Plasma Spraying; Suspension Plasma Spraying; Thermal Conductivity; Thermo-cyclic fatigue; Thermal Shock; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Thermal barrier coatings (TBC’s) are used to provide both thermal insulation and oxidation protection to high temperature components within gas turbines. The development of turbines for power generation and aviation has led to designs where the operation conditions exceed the upper limits of most conventional engineering materials. LÄS MER

  7. 35. Thick and Thin Ti2AlC Coatings

    Författare :Jenny Frodelius; Lars Hultman; Per Eklund; Hans Högberg; Lars Nyborg; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This Thesis explores the deposition techniques of magnetron sputtering and high velocity oxy-fuel (HVOF) spraying for Ti2AlC as a promising high-temperature material. Magnetron sputtering aims at producing thin (≤1 μm) Ti2AlC films of high crystal quality for use as a model system in understanding the material’s basic properties. LÄS MER
