Resumen:
The corrosion performance of steel/55%Al-Zn alloy sheets pre-treated with 5% Fe (NO3)3 + 15% H3PO4 solution, and then coated with acrylic (AC), alkyd (AQ), vinyl (VL), solvent based epoxy (ES) or waterborne epoxy (EA) corrosion-inhibiting primers + a barrier topcoat alkyd paint was studied. Exposure conditions included weathering chambers and natural atmospheres (La Plata-Argentina and San Luis-Potosi, Mexico). The panels? behavior was evaluated through visual inspections and EIS measurements. Their results allowed inferring that: 1) most of the painting systems have a satisfactory performance during their exposure to the accelerated weathering chamber or the natural atmospheric stations; and 2) the correlation between them allowed explaining some problems arising in service. This information will allow extending the useful life by adjusting the painting system formulation.
