METHOD FOR PRODUCING A COATING WITH LOW SURFACE ENERGY AGAINST BIOFOULING Russian patent published in 2021 - IPC B63B59/04 

FIELD: coatings.

SUBSTANCE: invention relates to methods for producing coatings protecting against biofouling of hulls of ship and hydraulic buildings, apparatuses, structures operated in the marine environment. Proposed is a method for producing a coating with low surface energy against biofouling on metal surfaces, including consecutive application of a metal sublayer and a surface layer onto the surface, wherein a transitional metal layer is optionally applied, wherein a metal sublayer of a zinc-aluminium-magnesium alloy with a thickness of 100 to 1000 mcm is first applied by arc deposition, then a polymer component is injected into the metal spraying jet so as to produce a transitional metal coating, followed by deactivating the metal spraying jet and applying a surface polymer layer with a thickness of 50 to 200 mcm using the polymeric component, then the coating is heat-treated with a gas flame to a temperature of 360 to 380°C, wherein a fluoroplastic suspension is used as a polymer component.

EFFECT: reduced power consumption for implementation of the method for producing coatings, absence of restrictions in the area of the coating, increase in the operational characteristics of the created coatings.
