    Abstract: An improved method for the fluorination of a diamond surfaces comprises condensing a layer of perfluorinated alkyl iodides consisting of C.sub.n F.sub.2n+1 I (where n is a positive integer from 1 to 13) on the diamond surface, producing perfluorinated alkyl free radicals by photodecomposing C--I bonds of said perfluorinated alkyl iodides on the diamond surface, reacting the diamond surface with photochemically produced perfluorinated alkyl radicals thereby anchoring photochemically induced photofragments of the perfluorinated alkyl iodides to the diamond surface forming a perfluorinated alkyl layer, and decomposing the perfluorinated alkyl layer on the diamond surface to cause the fluorination of the diamond surface by atomic F. The method achieves greater than one fluorine atom per surface carbon atom chemisorbed on the diamond using C.sub.4 F.sub.9 I. A fluorinated diamond made by the above method is also disclosed wherein a fluorinating perfluoroalkyl iodide, C.sub.n F.sub.2n+1 I, is selected from the group consisting of n=1 to 5. In one case, the fluorinating perfluoroalkyl iodide is C.sub.4 F.sub.9 I. In another case, it is CF.sub.3 I.

    Abstract: An improved method for the lubrication of diamond-like carbon surfaces comprises condensing a layer of perflourinated alkyl halides of the formula C.sub.n F.sub.2n+1 X, wherein n is a positive integer from 1 to 13 and X is selected from I, Br and Cl, on the diamond-like carbon surface. Perflourinated alkyl free radicals are then produced by photodecomposing C--X bonds of said perflourinated alkyl halides on the surface. The diamond-like carbon surface is reacted with photochemically produced perflourinated alkyl radicals thereby anchoring photochemically induced photofragments of the perflourinated alkyl halides to the surface forming a perflourinated alkyl layer. The perfluorinated alkyl layer is preferably decomposed on the diamond-like carbon surface to cause the fluorination of the surface by atomic F. The method preferably achieves greater than one fluorine atom per surface carbon atom chemisorbed on the diamond-like carbon. The fluorination process produces lubricated diamond-like carbon surfaces that are particularly suitable for computer hard disks.
