Way of composite coating application used for materials surface protection

The invention relates to a method of forming a composite coating on the surface of the material in which the material inserted into the galvanizing bath containing Zn in a concentration of 8 to 15 gl-1 and the aqueous dispersion of polytrifluoroethylene or polytetrafluoroethylene at a concentration of 5 to 30 vol.%, Wherein the dispersion contains particles with concentration of 15-65 vol.% and their size is in the range of 0.15 to 0.35 microns, and then the coating proceeds at elimination rate from 0.15 to 0.3 .mi.m.min-1 at a voltage of 1 to 10 V, a current density of 1-5 A.dm-2, a bath temperature of 18-32 ° C and pH 3 to 12. Separated composite coating on the surface of the material contains 0.01 to 40 wt. % polytrifluoroethylene or polytetrafluoroethylene in powder and / or paste with a particle size up to 10 microns and the coating thickness is 35 microns.
