1. 11. Behavior of cutting tool coating material Ti1-xAlxN at high pressure and high temperature

   Kandidat-uppsats, Institutionen för fysik, kemi och biologi

   Författare :David Dilner; [2009]
   Nyckelord :thin film physics; hard coatings; Ti1-xAlxN; diamond anvil cell; high pressure and high temperature; cutting tools; cutting test; nanoindentation; XRD;

   Sammanfattning : The high pressure and high temperature (HPHT) behavior of Ti1-xAlxN coatings on cutting tool inserts have been of interest for this diploma work. A literature study of HPHT techniques as well as measurement methods has been done. LÄS MER

3. 12. Characterization of Oxygen-rich Ti2AlC Thin Films

   Master-uppsats, Institutionen för fysik, kemi och biologi

   Författare :Aurelija Mockute; [2008]
   Nyckelord :Ti2AlC; MAX phases; nanoindentation; mechanical properties; deformation;

   Sammanfattning : In this Thesis Ti-Al-C thin films deposited by cathodic arc at 700, 800 and 900 °C were investigated with respect to composition, structure and mechanical properties. The highest growth temperature resulted in close to single crystalline Ti2AlC MAX phase.   A high oxygen incorporation of 7-12 at. LÄS MER

4. 13. Electrostatic Feedback for Mems Sensor : Development of in situ TEM instrumentation

   Uppsats för yrkesexamina på grundnivå, Institutionen för fysik, kemi och biologi

   Författare :Huai-Ning Chang; [2008]
   Nyckelord :Electrostaitc force modeling; Force feedback; Force sensor;

   Sammanfattning : This thesis work is about further developing an existing capacitive MEMS sensor for in situ TEM nanoindentation developed by Nanofactory Instrument AB. Today, this sensor uses a parallel plate capacitor suspended by springs to measure the applied force. The forces are in the micro Newton range. LÄS MER

5. 14. Nanoindentation in situ a Transmission Electron Microscope

   Uppsats för yrkesexamina på grundnivå, Institutionen för fysik, kemi och biologi

   Författare :Lars Johnson; [2007]
   Nyckelord :nanoindentation; electron microscopy; mechanincal deformation; thin films; MAX phases; functional ceramics;

   Sammanfattning : The technique of Nanoindentation in situ Transmission Electron Microscope has been implemented on a Philips CM20. Indentations have been performed on Si and Sapphire (α-Al2O3) cut from wafers; Cr/Sc multilayers and Ti3SiC2 thin films. Different sample geometries and preparation methods have been evaluated.
