| Abstract: |
| Objective To improve the restriction of Rotary Mechanical Plating equipment on the size of parts and achieve zinc coatings for larger parts. Methods A novel method for Mechanical Plating was presented using ultrasonic vibrations to provide motives for impact media to realize zinc coating on metallic surfaces. The surface topography and section morphology of the coating were observed. The bonding strength between the coating and the substrate was tested. The corrosion resistance of the coating was evaluated by the salt spray test. Results The new process had good performance in zinc plating and a certain thickness of zinc coating could be obtained. The finish of zinc-coating gained by new process was fine, uniform and smooth, and the whole surface of the coating was flat without uneven structure. The coating was fabricated by zinc powders. The bonding strength between the coating and substrate was high and the corrosion resistance of the coating was good. Conclusion Zinc coatings could be obtained for larger parts by the Wet Mechanical Plating process. |
