On increasing demand of smooth surfaces in many industries has exerted a significant thrust to develop new methods for rapid post-processing of parts. The existing polishing methods are limited to polish free-form surfaces and complex geometries. The chemical-based techniques such as electrochemical (EP) and plasma electrolytic polishing (PeP) have the advantages to fulfill drawbacks. The EP process utilizes aggressive media such as acids, whereas in PeP, low concentrated environment-friendly salt solution is used. In this work, we utilized PeP process for polishing of stainless steel AISI 304 samples. The experiments were carried out to investigate the behavior of current according to different applied voltages and their effect on surface roughness. The study suggested that in PeP, high voltage results in quick formation of vapor gas envelope followed by initiation of plasma stream hence instant reduction in current.

摘要

On increasing demand of smooth surfaces in many industries has exerted a significant thrust to develop new methods for rapid post-processing of parts. The existing polishing methods are limited to polish free-form surfaces and complex geometries. The chemical-based techniques such as electrochemical (EP) and plasma electrolytic polishing (PeP) have the advantages to fulfill drawbacks. The EP process utilizes aggressive media such as acids, whereas in PeP, low concentrated environment-friendly salt solution is used. In this work, we utilized PeP process for polishing of stainless steel AISI 304 samples. The experiments were carried out to investigate the behavior of current according to different applied voltages and their effect on surface roughness. The study suggested that in PeP, high voltage results in quick formation of vapor gas envelope followed by initiation of plasma stream hence instant reduction in current.
