Corrosion resistance of Ni-based coatings deposited by spray and fuse technique varying oxygen flow

The corrosion behavior of the Ni-based coatings and substrate were evaluated by potentiodynamic polarization using a NaCl 3.5% solution. The chemical composition in the corrosion areas of the coatings showed that corroded zones are Cl structures. Finally, the study established a relationship between the crystallographic parameters and the corrosion resistance.
