  5. 14. Tribological testing of top hammer drill buttons

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Carl Johan Hassila Karlsson; [2016]
    Nyckelord :tribology; wear; cemented carbides; WC-Co; sandstone; granite; rock drilling; top hammer drilling; wear test; friction;

    Sammanfattning : In the present work further modifications are implemented to an existing test setup for the evaluation of the wear of cemented carbide drill buttons in rock drilling applications. The test setup has been evaluated in previous diploma works, which has shown that the test successfully mimics the wear seen in rock drilling applications. LÄS MER
