Description | The main objective of our work is the characterization of a-C and a-C:H thin films and the comparison between the properties of such films deposited using several techniques like low pressure radio frequency plasma enhanced chemical vapor deposition (PECVD), reactive magnetron sputtering, thermionic vacuum arc (TVA) and gaseous TVA. The depositions were made on glass and single crystalline silicon substrates. We focused our attention on the following coating properties: hardness, elastic modulus, fracture toughness, film-substrate adhesion. The mechanical tests were performed using continuous stiffness measurement (CSM), depth sensing indentation (Fisherscope) and dynamic mechanical analysis (DMA-UNHT). The morphology of the film surface before and after indentation tests was examined using scanning electron and atomic force microscopy (SEM, AFM). |
