  1. 1. Desalination of Archaeological Iron Objects in Vacuum

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Aleksi Pienimäki; [2023-12-13]
    Nyckelord :Archaeological iron; desalination; vacuum;

    Sammanfattning : This work investigates the efficiency of commercially available vacuum containers as a physical deoxygenation method for desalination solutions for archaeological iron. Other factors are investigated as well, such as the effect of cleaning the objects of their corrosion crusts before treatment and drying them between subsequent treatment baths. LÄS MER

  3. 2. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Gabriella Zimmerman; [2023-11-07]
    Nyckelord :plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

    Sammanfattning : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. LÄS MER

  4. 3. Relationship between Fatigue Properties and Surface Treatment of Aluminum Alloy

    H-uppsats,

    Författare :Umair Ali Khan; Soroosh Zahedi; [2023-09-14]
    Nyckelord :Corrosion resistance; Fatigue; Aluminium alloys; HPDC; PMC; Sheet Metal; Anodization Molding; Casting;

    Sammanfattning : Corrosion has posed a significant challenge within the maritime sector for numerousyears. In the 21st century, bolstering the corrosion resistance of alloys, particularlyaluminum alloys, has become paramount. Aluminum alloys find widespread use inpropulsion systems, boat hulls, and cargo vessels. LÄS MER

  5. 4. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ahsan Ali; [2023]
    Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

  7. 5. Validation of sPEeD: A study aimed to validate the analysis program sPEeD12953

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Mathias Strinnholm; [2023]
    Nyckelord :Master thesis; shell boiler; corrosion; creep; validation; EN12953; European standard; Examensarbete; eldrörspanna; korrosion; kryp; validering; EN12953; europeisk standard;

    Sammanfattning : Shell boilers used in Sweden and Europe has to be certified before being used. Kiwa Sweden performs the role as an accredited third party for control services within most industries in Sweden. Kiwa Sweden has acquired an analysis program called  sPEeD12953 from the danish company Danish Exergy Technology (DXT). LÄS MER
