This work presents a methodology to fabricate zeolite coating on aluminum and magnesium alloys. A procedure for coating AA 6082 aluminum and AZ31B magnesium alloys substrates with a homogeneous, adherent and anticorrosive layer of a zeolite filler embedded in a silane matrix is developed. The adhesion of the coating has been probed by scratch and shear tests. Furthermore, the coating strength at high strain rate has been tested by tensile impact testing method. Also, the corrosion resistance of the coated samples has been verified highlighting an improvement with respect to the uncoated materials. The overall results show a very good surface coverage grade and a good level of coating adhesion and strength.
