与机械抛光相比,电解抛光制备金相试样具有省工、省时、成本低、质量高等优点。本文对几种常用的金属在不同热处理状态下的金相样品进行了电解抛光试验。从电解液成分、槽端电压、电流密度、电解时间及试样制备等方面进行了研究,提出了金相试样适宜的电解液及抛光工艺制度。 Compared with mechanical polishing, electropolishing metallographic sample preparation has the advantages of saving labor, saving time, low cost and high quality. In this paper, several commonly used metals in different heat treatment of the metallographic samples were electrolytic polishing test. From the aspects of electrolyte composition, cell voltage, current density, electrolysis time and sample preparation, the suitable electrolyte and polishing process for metallographic samples are proposed.
