Research > Laboratory of Surface Science and Engineering
This laboratory offers a pluridisciplinary approach to the optimization of materials surface, with the objective of their adaptation to the various mechanical constraints in their chemical and thermal environment.
The specific scientific objectives associated with this approach are developed along the following topics :
surface treatment processes engineering
study of the thermochemical treatment processes and of the chemical and physical deposition processes in gaseous phase modeling and numerical simulation or reactors behavior
optimization of materials before surface treatment. Physicochemical and structural characterization of transformed surfaces local and fine characterization of the composition and microstructure of transformed surfaces (size and orientation of coating crystallites, level of crystallinity, quality of interfaces, physico-chemistry, concentration profiles). development of the theoretical models of crystal growth or of diffusion-precipitation design of local correlations between the processes and the structures of transformed surfaces (development of an efficient engineering process of surface treatment ) study of the first stages in surface reactions
mechanical characterization of transformed structures behavior laws of multilayers, internal constrains, brittleness. contact mechanics and tribology mechanical modeling correlations between structures and mechanical properties of transformed surfaces (development of structures and architectures of optimized coatings for specific contact conditions).
