The objective of this research was to evaluate corrosion resistance by the salt spray test in A36 structural steel coated with alkyd paint incorporating zinc oxide nanoparticles. Industrial ZnO nano were used, which were characterized by infrared spectroscopy with Fourier transform (FTIR), UV-visible spectroscopy scanning electron microscopy (SEM) and X-ray diffraction (XRD). The incorporation of zinc oxide nanoparticles in the alkyd paint was performed in percentages by weight of 0.5; 1.5 and 3.0. The evaluation of the incorporation of these nanoparticles on the metallic substrate was performed by FTIR, SEM-EDS and XRD. Finally, the salt spray accelerated corrosion test was performed, with a 5.0%w NaCl saline solution. The results of the nano-ZnO characterization indicated that the nanoparticles show the wurtzite-type hexagonal crystal with structure, with, sensitivity to UV-vis light with characteristic band in the ultraviolet spectrum, and in the case of FTIR showed a characteristic band in the range of 400-500cm-1. The incorporation of nano-ZnO concentration in alkyd paint 0.5%w showed a better surface appearance compared to 1.5 and 3.0%w which showed a more rough appearance. The highest corrosion resistance was shown by the concentration of 1.5% w of nano-ZnO in the accelerated salt spray corrosion test.
