Abstract

"PROCESSO DE REVESTIMENTO DE SUPERFìCIES METáLICAS". Através de enxerto ("grafting"), que compreende as etapas de promover uma imersão da superfície a ser revestida, ativando-a por um elemento "iniciador" que remove prótons (H+) da superfície de hidróxido de metal, produzindo-se radicais livres que estão disponíveis para a reação com os monómeros; aplicar uma quantidade de monómeros selecionados que se acoplam aos radicais livres promover uma transformação dos monómeros em polímeros (polimerização); promover a interrupção do processo assim que se esgotem os elétrons livres, resultando no "enxerto" através da união por ligações químicas do material depositado com as próprias moléculas do óxido do metal, tornando-o revestido."METAL SURFACE COATING PROCESS". By grafting, which comprises the steps of promoting a dip in the surface to be coated by activating it by a primer which removes protons (H +) from the metal hydroxide surface, producing free radicals. which are available for reaction with the monomers; applying a number of selected monomers that couple to free radicals promote a transformation of the monomers into polymers (polymerization); promote the interruption of the process as soon as the free electrons are depleted, resulting in "grafting" through the chemical bonding of the deposited material with the metal oxide molecules themselves, making it coated.
