摘要
Method of inhibiting the deposition, on a metallic surface, of products resulting from the thermal degradation of hydrocarbons, wherein a polymeric coating based on polyvinylidene fluoride is deposited on the said surface, characterized in that: the said coating is composed of a mixture of a polyvinylidene fluoride homopolymer or of a polyvinylidene fluoride copolymer, the other components being present in a proportion of 1% to 20% by weight of the polymer, and a glass; the said coating is obtained from a mixture of polymer particles having a flow index of 10 to 300 grams per 10 minutes, as determined in accordance with the standard ASTM D1238, condition J, and spherical or ovoid glass particles with a size of between 1 and 300 µm; the ratio between the percentages by mass of the glass and of the polymer is between 0.05 and 0.50; and the coating is obtained by a fluidized bed process, or by an electrostatic process, or by compressed air, or by flame vaporization, or by electrostatic fluid bed. Metallic component thus coated, such as an engine injector.
