1. Growth and Nano-structural Studies of Metallic Multilayer for X-ray Mirrors
Sammanfattning : A part of the Ph.D. project focused on growth and characterization of metal multilayers is presented in this licentiate thesis. The main interest in carrying out this research is to develop highly reflective normal-incidence condenser mirrors for soft X-ray microscopy studies in the water window (λ=2. LÄS MER
2. Materials Science of Multilayer X-ray Mirrors
Sammanfattning : This thesis treats the reflective and structural properties of multilayer structures. Soft X-ray multilayer mirrors intended as near-normal incidence reflective optics and polarizers in the water window (λ=2.4-4.4 nm) are the main focus. LÄS MER
3. Mechanical properties and thermal stability of reactive arc evaporated Ti-Cr-Al-N coatings
Sammanfattning : This licentiate thesis reports experimental and theoretical work on the high temperature mechanical properties and the thermal stability of cubic (c)-(Ti-Cr-Al)1-N1 coatings. It is demonstrated that it is possible to tailor and improve the properties of hard nitride coatings by different degrees of multicomponent alloying. LÄS MER
4. Multicomponent Alloying for Improved Hard Coatings
Sammanfattning : Coatings are vital to protect and to increase the productivity of cutting tools in high speed and dry cutting applications. During the cutting operation the temperature may exceed 1000 ºC it is therefore necessary that the coatings withstand high temperatures. LÄS MER
