【 摘 要 】

Electrolytic plasma polishing (EPP) is an emerging technology for polishing, cleaning, deburring and smoothing of free-formed metal surfaces. The electrolytic plasma polishing of outer metal surfaces is state-of-the-art, whereas the polishing of pipe inner surfaces has only recently been reported by the authors. A prototype system and first experimental results were presented. It was found in the previous study that the average surface roughnessSareaches a range from 0.065 µm to 0.090 µm. The current study systematically investigates the influence of the velocity v as well as the number n of polishing passages on the average surface roughnessSa . The polishing of the pipe inner surface and weld seam are considered separately. The results show that the average roughnessSais mainly dependent on the effective polishing time te p tof the polishing process. The average surface roughnessSaof the pipe inner surface can reach a range from 0.030 µm to 0.034 µm starting from an initial surface roughness Sa 0of 0.719 µm, whereas the average surface roughnessSaof the weld seam can reach a range from 0.088 µm to 0.096 µm starting from an initial surface roughness Sa 0 of 0.282 µm. These ranges are achieved after an effective polishing time of approximately 25 s for both the inner pipe surface and the weld seam.
