Synthèse et caractérisation de revêtements nanostructurés à base de nitrures de titane et de zirconium obtenus par évaporation par arc électrique sous basse pression

Abstract : The present study concerns the synthesis and the characterisation of zirconium and titanium nitride based nanostructured films deposited by a non-polluting surface treatment process: low pressure electric arc evaporation. In a first chapter, his technique and its related phenomena are described as well as sorne experimental observations. After a description of the experimental deviee and of sorne specifie analysis methods, we investigate the deposition conditions-properties relationship of binary titanium and zirconium nitrides. This preliminary work allowed the optimisation of the deposition conditions of this new process for the la bora tory as well as the definition of references for the following. Indeed, we present the deposition and the characterisation of titanium-zirconium nitrides coatings enriched in boron and then those of titanium ni tri de enriched in copper. The first category yields hard (51-53 Pa) Zr(Ti)-N-B/BN nanostructured coatings presenting low surface energy polar components (6,5 mJ.m-2 ) and excellent impermeability associated with a strong chemical inertia versus molten aluminium. Investigating the second category of coatings targeted to contribute to the understanding of the rather important hardness increase of composite ceramic-smooth metal.
