The character of friction coefficient fluctuation of coatings from Fe-Cr-B-Al and Fe-Cr-C-Al with additives of solid lubricants such as CaF2 and Fe2P was investigated and addition of Fe2P in coatings promotes increase of the wearprofness in 3 times was shown. The seepage of the coatings by synthetic oil with next exposure in furnace during 1 hour at 300 C causes creating the polimer film in voids and on surface which provides enhancement of wearprofness was investigated.
