  4. 4. Evaluation of HVAF sprayed STR coatings

    Uppsats för yrkesexamina på avancerad nivå, Tillämpad materialvetenskap

    Författare :Robin Elo; [2012]
    Nyckelord :HVAF; coating; Cr3C2-NiCr; WC-Co; WC-CrC-Ni;

    Sammanfattning : The Seamless Stressometer® roll (Seamless STR) is used to measure the flatness of aluminum and steel strip when there is an extreme demand on the surface finish. To protect the roll and strip, the roll is coated with two layers deposited by high velocity oxygen fueled spraying (HVOF), Cr-Ni(Si,B) closest to the roll and WC-Co on top. LÄS MER

  5. 5. Identification of business cases for HVAFtechnology

    Master-uppsats, KTH/Industriell Management
