TL;DR: In this paper, the contact resistance of Ag2S films on pure silver and on gold-silver and palladium-silver alloys was investigated, and it was shown that the desirable properties of silver sulfide properties are unique only to films made from pure silver.
Abstract: Studies were made of the contact resistance of Ag2S films on pure silver, and on gold-silver and palladium-silver alloys. Although relatively thick films of Ag2S on silver gave low contact resistance, equivalent film thicknesses on other substrates gave contact resistance values that were orders of magnitude higher. These results were attributed to mechanical rather than electrical-property differences of either the films, the substrates, or an interaction of both. Data clearly indicate that the "desirable" properties of silver sulfide are unique only to films on pure silver.

TL;DR: The graphite fluoride is both oleo and hydro phobic and has very good wear resistance as discussed by the authors and can be used in the plating bath and surface finishing and reflectivity increasing reagents can also be added.
Abstract: Permanently lubricated plate surfaces on metal components can be mfrd. by deposition of 0.1-10 g/l graphite fluoride polymer finely ground form a plating bath contg 10-500 mg/l of surface active cpd. contg. C-F linkages. The graphite fluoride is both oleo and hydro phobic and has very good wear resistance. The surface active reagent must be cationic, non-ionic or amphoteric to allow electrophoretic co-deposition of the graphite fluoride polymer. Most metals, e.g. Ni, Pb, etc., may be used in the plating bath and surface finishing and reflectivity increasing reagents can also be added.
