| Abstract: |
| Objective To explore the influencing law of the ultrasonic power on the corrosion resistance of the coating. Methods Under the four levels of ultrasonic power(50, 70, 90, 110 W),four kinds of mechanical zinc-coatings were prepared by Wet ultrasound mechanical galvanizing equipment. The surface topography of the coatings was observed and studied by SEM. The coatings thickness was measured, the corrosion resistance was determined and the bonding strength between the coating and the substrate was studied. Results When the ultrasonic power was 50 W, the corrosion resistance and surface quality of the zinc-coating were worse than those of others. While the corrosion resistance and surface quality of the zinc-coating were the best when the ultrasonic power was 110 W. Conclusion The surface quality of the coating was significantly improved and the corrosion resistance of the coating showed an increasing trend with increasing power. |
