1. 21. Microstructural evolution of TiAlN hard coatings at elevated pressures and temperatures

   Författare :Niklas Norrby; Magnus Odén; Mats Johansson; Jean-François Pierson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A typical hard coating on metal cutting inserts used in for example turning, milling or drilling operations is TiAlN. At elevated temperatures, TiAlN exhibits a well characterized spinodal decomposition into coherent cubic TiN and AlN rich domains, which is followed by a transformation from cubic to hexagonal AlN.

3. 22. TiAlN-based Coatings at High Pressures and Temperatures

   Författare :Robert Pilemalm; Magnus Odén; Mikael Olsson; Rachid M'Saoubi; Mats Jöesaar; Linköpings universitet; []
   Nyckelord :Materials science; thin films; coatings; spinodal decomposition; TiAlN; TiZrAlN; HPHT; high pressure high temperature; BELT-press; transmission electron microscopy; x-ray diifraction; microhardness;

   Sammanfattning : 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. LÄS MER

4. 23. High temperature behavior of arc evaporated ZrAlN and TiAlN thin films

   Författare :Lina Rogström; Magnus Odén; Lars Hultman; David Rafaja; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Hard coatings can extend the life time of a tool substantially and enable higher cutting speeds which increase the productivity in the cutting application. The aim with this thesis is to extend the understanding on how the microstructure and mechanical properties are affected by high temperatures similar to what a cutting tool can reach during operation.

5. 24. Defects in Titanium Aluminum Nitride-Based Thin Films

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

   Sammanfattning : 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. 25. Defect-engineered (Ti,Al)N thin films

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

   Sammanfattning : 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.
