Abstract:
In a process for producing a coating on components having peripheries to be brought into direct contact with at least one of vapor and condensate of a medium, the improvement which comprises:roughening the peripheries of the components to a depth of up to 20 &mgr;m; applying to the peripheries a coat up to 5 &mgr;m thick of a non-wettable, amorphous carbon with a formula: a-C:H:X, where X is a chemical element selected from the group consisting of fluorine and silicon, to produce coated surfaces having uncoated regions and regions coated with the non-wettable, amorphous carbon; and then smoothing the coated surfaces to produce an overall surface area of the uncoated regions being less than 50% of an overall surface area of the regions coated with the non-wettable, amorphous carbon.
