Abstract
This work is devoted to the study of new ceramic-polymer coatings formed by microarc oxidation (MAO) method during friction in environmentally saved lubricants using polyalphaolefin (PAO), polyethylene glycol (PEG) and diisotridecyl adipate (DITA). The coatings were formed in a weakly alkaline electrolyte with the addition of a fluoroplastic suspension using a cyclic mode. To improve the adhesion strength of fluoroplastic to the oxide matrix, additional heat treatment was performed. The resulting ceramic-polymer coatings consist of an oxide matrix with fluoroplastic particles embedded in it. Tests have shown that new ceramic-polymer coatings have improved tribological characteristics relative to traditional MAO coatings at the friction both to steel and to the eponymous surface.
