   Sammanfattning : This thesis work is focused on the influence of process parameters during gas atomization on the thermal spraying properties of a Ni-Cr-B-Si hardfacing alloy. The metal powder alloy, known as 1-60-20, is produced by Höganäs AB. LÄS MER

3. 2. 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
