電漿電解拋光（PEP）是一種創新的表面處理技術，相較於傳統的電解拋光，PEP能夠實現更低的表面粗糙度和更高的光澤度，並且可以提高材料的耐腐蝕性。在本文的第一部分，我們將從宏觀和微觀兩個角度介紹PEP技術的基本原理。在第二部分中，我們進一步討論了PEP工藝的典型特徵和現象，並對主要參數進行了詳細的分析，包括材料去除率、電解液和工作電壓等。最後，在COMSOL®中類比了粗糙度的變化，並對所選加工材料的PEP表面粗糙度尺寸進行了統計分析。綜合以上結果，本文為PEP技術的應用提供了重要參考。

Plasma Electrolytic Polishing (PEP) is a novel surface treatment technology that enhances corrosion resistance and achieves low roughness and high gloss, providing numerous advantages over electropolishing. This study presents the fundamental principles of PEP technology, including its macro and micro mechanisms. The paper summarizes the typical features and phenomena of the polishing process and discusses critical parameters such as material removal rate, electrolyte, and operating voltage. Using COMSOL®, the study simulates the effect of these parameters on roughness change and statistically reviews the impact of parameter changes on the surface roughness of the selected processing material.
