In this research the results of resistance changes for carbonaceous-palladium films taking place under the influence of
gaseous surrounding with the contents of 1% H2, 99% N2 have been presented. The films were received by PVD method
and their characteristics from the point of view of topography and morphology was done using scanning electron
microscope (SEM). The films with different contents, surface topography and morphology were investigated from the
point of view of resistance changes taking place under the influence of gaseous surrounding. These changes can be
correlated with the changes of Pd contents.
