  1. 1. Deposition and Phase Transformations of Ternary Al-Cr-O Thin Films

    Författare :Ali Khatibi; Lars Hultman; Per Eklund; Jon Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin Films; Hard Coatings; Mathematical physics; Matematisk fysik;

    Sammanfattning : This thesis concerns the ternary Al-Cr-O system. (Al1-xCrx)2O3 solid solution thin films with 0.62 gas mixture. As-deposited and annealed (Al1-xCrx)2O3 thin films were analyzed by x-ray diffraction, elastic recoil detection analysis, scanning electron microscopy, transmission electron microscopy, and nanoindentation.

  3. 2. Growth and Heat Treatment Studies of Al-Cr-O and Al-Cr-O-N Thin Films

    Författare :Ali Khatibi; Lars Hultman; Per Eklund; Marcus Morstein; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Aluminum oxide based thin films are applied on cutting tool inserts as a top layer to protect the underlying nitride or carbide functional layer from the harsh working environment in terms of abrasive and chemical wear under thermal and pressure load. This Thesis explores the synthesis and characterization of the next generations of multifunctional wear-resistant thin film coatings in the form of Al-Cr-O and Al-Cr-O-N compounds. LÄS MER
