1. 1. 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. 2. Reactive Sputtering of Complex Multi-component Nitride Thin Films

   Författare :Kristina von Fieant; Erik Lewin; Ulf Jansson; Jean-Francois Pierson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The ever-increasing demand on improvement of protective nitride thin films has led to an expansion of the research field into multi-element based materials. The work in this thesis has focused on exploring new complex, multi-component nitride thin films based on three different material systems: Al-Ge-N, Hf-Nb-Ti-V-Zr-N and Al-Cr-Nb-Y-Zr-N. LÄS MER
