Coatings deposited on polymers are widely used in manyindustrial applications such as optical, microelectronic,packaging, biomedical and decorative. Related to these uses, mechanical properties of coating and coating-substrate interface have to be controlled because they play a crucial role in coating efficiency. This work deals with the characterization of different systems based on stiff and hard PEO/SiO hybrid coatings deposited onto 2 a soft PVC substrate using fragmentation and depth sensing indentation tests. The influence of processing variables on the coating and interface properties was investigated
