Abstract

The morphology and corrosion behavior of Ni-Al₂O₃ composite coatings prepared by double-pulsed technique and oxidized under high temperature were analyzed by SEM, XRD and EDX. The results showed that the corrosion of all composite coatings is accelerated under NaCl deposits, and the corrosion products are rather porous with poor adherence to the matrix. Al₂O₃ particles in the coatings can refine the grain size and improve the high temperature corrosion resistance of the coatings. Within the test scope, the more Al₂O₃ particles in the coatings, the lower corrosion rates could be obtained. The corrosion mechanism was also discussed.
