  1. 1. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Cecilia Nemeth; [2020]
    Nyckelord :high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

    Sammanfattning : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. LÄS MER
