  1. 1. Growth and Characterization of Amorphous Multicomponent Nitride Thin Films

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Hanna Fager; Linköpings universitet.; Linköpings universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis explores deposition of amorphous thin films based on the two transition metal nitride systems, TiN and HfN. Additions of Si, Al and B have been investigated using three different deposition techniques: dc magnetron sputtering, cathodic arc evaporation, and high power impulse magnetron sputtering (HIPIMS).

  2. 2. TiAlN-based Coatings at High Pressures and Temperatures

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Robert Pilemalm; Linköpings universitet.; Linköpings universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials science; thin films; coatings; spinodal decomposition; TiAlN; TiZrAlN; HPHT; high pressure high temperature; BELT-press; transmission electron microscopy; x-ray diifraction; microhardness;

    Abstract : TiAlN and TiAlN-based coatings that are used of relevance as protection of cutting tool inserts used in metal machining have been studied. All coatings were deposited by reactive cathodic arc evaporation using industrial scale deposition systems. The metal content of the coatings was varied by using different combinations of compound cathodes. READ MORE

  3. 3. Microstructure evolution of Ti-based and Cr cathodes during arc discharging and its impact on coating growth

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Jianqiang Zhu; Linköpings universitet.; Linköpings universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis explores the microstructure evolution of cathodes with various material compositions and grain sizes during cathodic arc evaporation processes as well as the impact on the arc movement, and the microstructure and properties of the deposited nitride coatings. The studied cathode material systems include conventionally metal forged Ti and Ti -Si cathodes, novel Ti3SiC2 MAX-phase cathodes, and dedicatedly designed powder-metallurgical Ti-Si and Cr cathodes with different grain size.

    Abstract : Metastable (Ti,Si)N alloy and TiN/SiNx multilayer thin solid films as well as SiNx/TiN surfaces have been explored. Cubic Ti1-xSixN (0≤x≤0. READ MORE

  5. 5. Nanostructuring and Age Hardening in TiSiCN, ZrAlN, and TiAlN Thin Films

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Lars Johnson; Linköpings universitet.; Linköpings universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thin films; age hardening; spinodal decomposition; TiSiCN; ZrAlN; TiAlN; Transmission electron microscopy; Atom probe tomography; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis explores nanostructuring in TiSiCN, ZrAlN, and TiAlN thin films deposited by cathodic arc evaporation onto cemented carbide substrates, with intended applications for cutting tools. The three systems were found to exhibit age hardening upon annealing, by different mechanisms, into the superhard regime (≥30 GPa), as determined by a combination of electron microscopy, X-ray diffraction, atom probe tomography, erda, and nanoindentation tech- niques.
