Abstract

L'invention concerne un revêtement de silane, une pièce à travailler métallique et un procédé de revêtement de surface associé. Le revêtement selon l'invention comprend de 5 à 20 g/L de 3-aminopropyltriéthoxysilane, de 50 à 300 mg/L de sel de cérium, de 10 à 50 mg/L de nano-oxyde, de 20 à 100 g/L d'agent de couplage silane, de 10 à 50 g/L d'éthanol et le reste d'eau. Ledit revêtement forme un revêtement polymère de silicone dense et ferme avec une surface métallique au moyen d'une liaison covalente ; et il permet de bloquer l'intrusion de substances corrosives et d'améliorer la résistance à la corrosion du métal, ce qui le rend approprié pour servir de base à un revêtement organique et aussi de couche protectrice finale.
