Compressive deformation and failure of CrAlN/Si3N4 nanocomposite coatings

Nanocomposite Based Multifunctional Coatings

Advanced Characterisation of Nanocomposite Coatings

Nanocomposite coatings are systems comprised of two or more phases. Such multiphase coatings are becoming increasingly important as they offer the possibility of tailoring the coating architecture and achieving exciting new properties. An understanding of the coating nanostructure is important to complete the classic processing-structure-properties relationship and expedite the development of n...

Hard Nanocomposite Coatings , Their Structure and Properties

Self-Lubricity of WSex Nanocomposite Coatings.

Transition metal chalcogenides with lamellar structure are known for their use in tribological applications although limited to vacuum due to their easy degradation in the presence of oxygen and/or moisture. Here we present a tailored WSex coating with low friction (0.07) and low wear rates (3×10(-7) mm3 Nm(-1)) even in ambient air. To understand the low friction behavior and lower chemical rea...

TiC-based nanocomposite coatings as electrical contacts

This Thesis concerns the advanced surface engineering of novel TiC-based nanocomposite and AgI electrical contact materials. The objective is to make industrially applicable coatings that are electrically conductive and wear-resistant, and have a low coefficient of friction. I have studied electrical contact systems consisting of a Cu substrate with a Ni diffusion barrier and loading support, a...
