  1. 1. Control of Wear-Resistance Properties in Ti-added Hypereutectic High Chromium Cast Iron

    Författare :Qiang Liu; Pär Jönsson; Keiji Nakajima; José Tinoco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High Chromium Cast Iron; cooling rate; Ti addition; M7C3; TiC; carbides size distributions; volume fraction; heat treatment; microstructure; mechanical properties; wear resistance;

    Sammanfattning : High chromium cast iron (HCCI) is considered as one of the most useful wear resistance materials and their usage are widely spread in industry. The wear resistance and mechanical properties of HCCI mainly depend on type, size, number, morphology of hard carbides and the matrix structure (γ or α). LÄS MER

  4. 3. Growth and Characterization of Ti-Si-N Thin Films

    Författare :Axel Flink; Lars Hultman; Paul Mayrhofer; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical transmission electron microscopy; Arc; Sputtering; Hard coatings; Multilayer Cutting inserts; analytisk transmissionselektronmikroskopi; ytbeläggningar; skärande; bearbetning; Ti-Si-N; arcförångning; sputtring; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : Utvecklingen inom materialforskningen går mot att framställa avancerade material vilka är skräddarsydda för olika tillämpningar. Detta har medfört att det blir allt mer populärt att belägga ytor med ett eller flera tunna lager med syfte att förbättra materialegenskaperna. LÄS MER
