Abstract

A process for producing a coating on components having peripheries to be placed in direct contact with vaporous media. Such peripheries are wetted over part or all of their surface with a film of liquid when the vaporous media are changed from the vapor state into the liquid state by phase transition. Such films of liquid increase the thermal resistance, for example, of the components. In order to avoid such wetting, the peripheries of each component are roughened. A coat of a non-wettable, amorphous carbon is then applied to the peripheries, at least in regions thereof.
