A new approach to the assessment of protective properties of amorphous hydrogenated carbon films is suggested that is based on studying the film wettability by solutions of different physico-chemical compositions. For a wide spectrum of water solutions of acids, bases, salts, organic liquids, surface-active substances and amorphous hydrogenated films, capillary properties (wettability, adhesion, interphase energy at the film–liquid interface) have been studied. The greatest change in σ sl is shown to occur in the film–alkali solution system. A protective action of a-C:H films from the point of view of their interaction with a medium has been verified for all types of contact systems under study.
