ABSTRACT
As the use of hexavalent chromium is now tightly regulated, researchers and industry have turned to new ways of obtaining anticorrosion coatings on metallic substrates. Based on molecular precursors in solution, film formation using sol-gel can achieve oxide networks at a moderate temperature through a series of hydrolysis-condensation reactions.

INTRODUCTION
With the use of hexavalent chromium now heavily regulated, researchers and manufacturers have turned their attention to new ways of obtaining anticorrosion coatings on metal substrates.
Sol-gel film formation enables oxide networks to be formed at moderate temperature from molecular precursors in solution, by a succession of hydrolysis-condensation reactions.
This is the process presented in this dossier.
