It has been established that polymer and metal modification is necessary to increase the adhesive strength and resistance of fluoroplastic coatings. The relative impact of the nature of the metal on the strength of adhesive compounds of polymer – metal is less influenced by the nature of the polymer. The strength of metal compounds is significantly affected by the activation of the metal surface by mechanical treatment (grinding etc.). Various methods of oxidation, etching, metal phosphating are recommended to increase the adhesive strength of fluoropolymer coatings. Method of investigation of adhesion and resistance to scratch damage of coatings is given. The influence of composition and temperature-time conditions of the ground layer formation of the coating on adhesive strength of metal-polymeric compounds was investigated. Detailed operation modes are described. The properties of the ground layer of fluoropolymer \u0424-30\u041f are given. The peculiarities of the fluoroplastic coating ground layer formation are outlined. The technology of application of the fluoroplastic coating ground layer on electroplating of metal surfaces has been developed. The coating on the metal surface was done by electrostatic spraying of the ground layer powder at an electric field voltage of 50 kV. The deformation and strength properties of the unstabilized \u0424-30\u041f fluoroplast are found to be quite high, which together with high adhesive strength makes it possible to recommend this polymer as primer. It is also advisable to melt the ground layers in more rigid temeperature-time modes (melting temperature 2600<\/sup> C, duration – 2 hours) in order to ensure\u00a0 higher adhesion strength. The adhesive strength of the \u0424-30\u041f fluoroplastic coating can be increased by 10-15% by additional heating at a temperature of 2400<\/sup> C for two hours. Analysis of the results showed that the resistance of fluoroplastic coatings based on \u0424-30\u041f to damage by scratching with an increase in the graphite content of C-1 from 15% to 25% increases by a factor of 2.11, and inserting to coating with 25 mas.% of C-1 graphite additional 3 mas. % of the aerosil-based amino-ergoholozenese – 3.16 times. The additional termoprocessing of these coatings increases the resistance to damage by scratching by 30 per cent. Recommendations on the use of research results for obtaining fluoroplastic coatings with high-adhesion to metal surfaces are given.
