Resum
This work reports the development of environmentally friendly coatings for the protection against corrosion of AZ91 magnesium alloy substrates. As a novelty, the synergic combination of the use of silica precursors and phosphonic acid molecules has been investigated for first time in the protection of AZ91 Mg alloy. Hybrid films have been prepared by the sol–gel synthesis using tetraethoxysilane (TEOS) and methylmethoxysilane (MTMS), as co-monomers; and 1,2-diaminoethanetetrakismethylenephosph...
