PROCESSO PARA FORMACAO DE UM REVESTIMENTO HIDROFILICO SOBRE A SUPERFICIE DE UM ARTIGO METALICO E ARTIGO DE MANUFATURA

摘要

The surfaces of articles of manufacture fabricated from aluminum or other metals which are not permanently hydrophilic are made permanently hydrophilic by coating the surfaces with a continuous film containing particles of activated alumina. The coated articles are not only hydrophilic, but also have good corrosion resistance and exhibit low abrasiveness, resulting in decreased wear on manufacturing tools, such as dies.
