Modelling and experimental studies of VN / TiN interfaces and surfaces

01.02.2006 - 31.01.2008

Research funding project

The aim of this project is the investigation of interfaces and surfaces as well as diffusion and oxidation processes in multilayers and superlattices by modelling and experimental approaches. The main goal is to develop a fundamental understanding of the atomic processes controlling the functionally of self-lubricating TiN / VN multilayers by combining experiment and ab-initio modelling to achieve an atomistic insight into the physical and chemical properties of VN and TiN interfaces and surfaces such as energetic stabilities, bonding, elastic and electronic properties. The interplay between surface and interface orientation, internal stresses and diffusion of V in dependence of the N-content, and through TiN layers will be analysed in order to optimise the design of industrial nano-sized TiN / VN multilayer coatings.
