FIELD: metallurgy.
SUBSTANCE: proposed method comprises electrolytic plasma oxidation in aqueous electrolyte containing PTFE powder particles. Note here that oxidation is performed in galvanostatic conditions at current density of 0.03-0.05 A/cm2 for 20-30 min in alkaline electrolyte containing 40-60 g/l of PTFE powder and, additionally, it comprises siloxane-acrylate emulsion in amount of 40-100 ml/g.
EFFECT: higher electrolyte stability, better wear resistance and hydrophobic properties of coatings.
