1. Triboactive Low-Friction Coatings Based on Sulfides and Carbides
Abstract : For sustainable development, it is highly important to limit the loss of energy and materials in machines used for transportation, manufacturing, and other purposes. Large improvements can be achieved by reducing friction and wear in machine elements, for example by the application of coatings. READ MORE

4. Me-Si-C (Me= Nb, Ti or Zr) : Nanocomposite and Amorphous Thin Films
Abstract : This thesis investigates thin films of the transition metal carbide systems Ti-Si-C, Nb-Si-C, and Zr-Si-C, deposited at a low substrate temperature (350 °C) with dc magnetron sputtering in an Ar discharge. Both the electrical and mechanical properties of these systems are highly affected by their structure. READ MORE

5. Transition metal carbide nanocomposite and amorphous thin films
Abstract : This thesis explores thin films of binary and ternary transition metal carbides, in the Nb-C, Ti-Si-C, Nb-Si-C, Zr-Si-C, and Nb-Ge-C systems. The electrical and mechanical properties of these systems are affected by their structure and here both nanocomposite and amorphous thin films are thus investigated. READ MORE
