  1. 16. Characterization of Electrodeposited Fe-based Metallic Coatings: Toward a Sustainable Approach

    Författare :Antonio Mulone; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrodeposition; structural characterization; coatings; electrodeposited tin; iron alloys;

    Sammanfattning : Electrodeposition has rapidly grown in the last 50 years and it has been applied to deposit metals and alloys with complex shapes or to produce fully dense nanostructures and amorphous coatings. Thanks to the achieved improved properties of the electrodeposited materials, electrodeposition has been applied in a wide set of applications including protective coatings, and magnetic and electronic applications.

  3. 17. Microstructure and wear mechanisms of textured CVD alumina and titanium carbonitride coatings

    Författare :Siamak Shoja; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plastic deformation; Texture; TKD; Electron microscopy; Coatings; CVD; TiCN; α-alumina; Wear mechanisms;

    Sammanfattning : The aim of this thesis is to find the reasons behind how the wear performance of hard coatings produced by chemical vapor deposition (CVD) is influenced by their texture, as this is today not fully known. Therefore, differently textured coatings were synthesized, and subsequently analyzed both before and after specially designed machining tests. LÄS MER

  5. 19. Microstructure and oxidation behavior of High Velocity Oxy-Fuel spray deposited Ti2AlC coatings

    Författare :Marie Sonestedt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coatings; High Velocity Oxy-Fuel HVOF ; Ti2AlC; oxidation; microstructure; SEM; TEM;

    Sammanfattning : Ti2AlC is one of the ternary carbides in the MAX phase group of materials. This group of materials have a unique combination of ceramic and metallic properties, such as machinability, high thermal conductivity, low density and oxidation resistance. LÄS MER

  7. 20. Influence of paper properties and polymer coatings on barrier properties of greaseproof paper

    Författare :Henrik Kjellgren; Gunnar Engström; Lars Järnström; Lennart Stolpe; Torbjörn Helle; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Greaseproof paper; Barrier properties; Gas barrier; Paper properties; Coatings; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Greaseproof paper has a dense structure and therefore provides a natural barrier against materials like fat and oils. The barrier is obtained by extensive refining of the pulp. LÄS MER
