Abstract
The paper presents the results of studying the interaction of microdischarges in the cell of dielectric barrier discharge (DBD) with enamel-based surface films deposited on a fabric-based laminate. TiO2 powder was added to the surface films. Elemental composition of the surface films was studied in the areas with different level of microdischarges exposure. Before measurement, the samples were bonded onto a 25 mm aluminum specimen with conductive silver paint. The metal was coated with a thin film (13 nm) of carbon using magnetron sputtering method. The observations were carried out using Hitachi SU8000 field-emission scanning electron microscope (FE-SEM). Images were acquired in secondary electron mode at 30 kV accelerating voltage and at working distance 8-15 mm. EDX-SEM investigation and mapping were carried out using Oxford Instruments X-max EDX system. Before measurement, the samples were coated with a thin film (13 nm) of carbon using Cressington 208 carbon coater. The study results showed significant effect of microdischarges in the DBD cell on elemental composition of surface films deposited on the fabric-based laminate surface.
