  2. 1. Defect-engineered (Ti,Al)N thin films

    Author : Isabella Citlalli Schramm Benítez; Frank Mücklich; Magnus Odén; Sven Ulrich; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates the effect of point defects (nitrogen vacancies and interstitials) and multilayering ((Ti,Al)N/TiN) on the phase transformations in cathodic arc-evaporated cubic (Ti,Al)N thin films at elevated temperatures. Special attention is paid to the evolution of the beneficial spinodal decomposition into c-TiN and c-AlN, the detrimental formation of wurtzite AlN and the potential application as hard coating in cutting tools.

  4. 2. Phase stability and defect structures in (Ti,Al)N hard coatings

    Author : Katherine M. Calamba; Magnus Odén; Jean Pierson; Mats Johansson; Gregory Abadias; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This study highlights the role of nitrogen vacancies and defect structures in engineering hard coatings with enhanced phase stability and mechanical properties for high temperature applications. Titanium aluminum nitride (Ti,Al)N based materials in the form of thin coatings has remained as an outstanding choice for protection of metal cutting tools due to its superior oxidation resistance and high-temperature wear resistance.

  6. 4. Defects in Titanium Aluminum Nitride-Based Thin Films

    Author : Janella Salamania; Magnus Odén; Lars Johnson; Lina Rogström; Zoe Barber; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thin films; Ti-Al-N; Defects; Physical vapor deposition;

    Abstract : Coatings and thin films inherently contain several types of defects. This thesis aims to enhance the understanding of the relationship of defects on the growth, structure, stability, and properties of titanium aluminum nitride films synthesized by physical vapor deposition techniques.

  7. 5. Growth and Phase Stability Studies of Epitaxial Sc-Al-N and Ti-Al-N Thin Films

    Author : Carina Höglund; Lars Hultman; Jens Birch; Daniel Gall; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : ¨This Thesis treats the growth and characterization of ternary transition metal nitride thin films. The aim is to probe deep into the Ti-Al-N system and to explore novel Sc-Al-N compounds. Thin films were epitaxially grown by reactive dual magnetron sputtering from elemental targets onto single-crystal substrates. READ MORE
