11. Design of carbide-based nanocomposite coatings
Sammanfattning : In this thesis research on synthesis, microstructure and properties of carbide-based coatings is reported. These coatings are electrically conducting, and can be tailored for high hardness, low friction and wear, along with load-adaptive behaviour. Tailoring these properties is achieved by controlling the relative phase content of the material. LÄS MER
12. Design, synthesis and characterisation of multilayered PVD coatings
Sammanfattning : Physically vapour deposited multilayered coatings were the target of this thesis.Several different wear resistant nitride coatings (TiN/CrN, TiN/MoN, TiN/NbN andTiN/TaN) have been evaluated. LÄS MER
13. Sputtering and Characterization of Complex Multi-element Coatings
Sammanfattning : The thin film technology is of great importance in modern society and is a key technology in wide spread applications from electronics and solar cells to hard protective coatings on cutting tools and diffusion barriers in food packaging. This thesis deals with various aspects of thin film processing and the aim of the work is twofold; firstly, to obtain a fundamental understanding of the sputter deposition and the reactive sputter deposition processes, and secondly, to evaluate sputter deposition of specific material systems with low friction properties and to improve their performance.

14. Magnetron Sputtering of Nanocomposite Carbide Coatings for Electrical Contacts
Sammanfattning : Today’s electronic society relies on the functionality of electrical contacts. To achieve good contact properties, surface coatings are normally applied. Such coatings should ideally fulfill a combination of different properties, like high electrical conductivity, high corrosion resistance, high wear resistance and low cost. LÄS MER
15. Tribology of Carbon Based Coatings for Machine Element Applications
Sammanfattning : Demands on lower fuel consumption, reduced pollution, increased operating times, etc. force the automotive industry to constantly improve the performance of critical machine elements. In this development various carbon based coatings have proven very promising, mainly because of their low friction and high wear resistance in dry sliding contacts. LÄS MER
