Recently, additive manufacturing technologies have begun to play a significant role in the industrial field due to the possibility to build complex, near-net-shape, and porous parts, optimizing costs, and time processing. Simultaneously, the high roughness of additively manufactured parts remains a critical drawback, limiting their use like an as-built component. Therefore, postprocessing treatments are needed. The electropolishing (EP) treatment could be ideal for simple, complex, or porous parts characterized by low surface quality. Herein, it is aimed to provide the state of the EP treatment's art carried out, to date, on additively manufactured parts made of titanium and Ti6Al4V alloy. A scientific literature research on EP of additively manufactured titanium and Ti6Al4V alloy is conducted using the Scopus database. The evaluation of recent research, still very few to date, reveals that a significant reduction of the roughness can also be achieved in complex shape additively manufactured parts. Although the EP is a versatile technique to reduce the roughness of additively manufactured parts, further studies are needed to improve its effectiveness, especially for complex and porous structures, to reduce the environmental impact of the materials used.

钛合金增材制造零件的电解抛光：最新技术

最近，增材制造技术开始在工业领域发挥重要作用，因为它可以构建复杂的、近净形状的多孔零件，优化成本和时间处理。同时，增材制造部件的高粗糙度仍然是一个严重的缺点，限制了它们像组装部件一样的使用。因此，需要进行后处理。电解抛光 (EP) 处理对于表面质量低的简单、复杂或多孔零件来说可能是理想的选择。在此，其目的是提供迄今为止对由钛和 Ti6Al4V 合金制成的增材制造部件执行的 EP 处理技术的状态。使用 Scopus 数据库对增材制造的钛和 Ti6Al4V 合金的 EP 进行了科学文献研究。最近的研究评估表明，在复杂形状的增材制造零件中也可以实现粗糙度的显着降低，但迄今为止仍然很少。尽管 EP 是一种降低增材制造零件粗糙度的通用技术，但仍需要进一步研究以提高其有效性，尤其是对于复杂和多孔结构，以减少所用材料对环境的影响。
