Machining of recent engineered complex materials such as aeronautical ones always require new tools to lower production cost and in the same time increase quality. One promising solution is the use of Chemical Vapour Deposition (CVD) diamond coatings on carbide tools, which is studied here. Diamond is used because of its extreme hardness, which made it a perfect candidate to reduce wear of the cutting edge. It is synthesized in a batch at low pressure and medium temperature directly on the tools. Deposition process on tungsten carbide tool bound with cobalt, which is the main industrial material for tool manufacture, and especially the adhesion of the diamond layer to the substrate has to be improved, and many research are focused on this point [

]. The whole process of deposition is described elsewhere [

]. This paper proposes an approach to study the decohesion of the diamond layer via a combination of experiments and simulation.
