Abstract

Additive manufacturing (AM) is a modern developing group of technologies based not on material removal, but on the layer-by-layer growth and synthesis of an object according to a CAD (computer-aided design) model. The main disadvantages of objects manufactured by AM technologies are a high degree of porosity and surface roughness. This study examines the possibility of modifying the surface of additive materials Ti\({}^{6}\)Al\({}^{4}\)V and AlSi\({}^{10}\)Mg by irradiation with Ar\({}^{+}\) ions with energies ranging from 2 to 9 keV. Using SEM, the surface topography was obtained before and after irradiation and mechanical polishing. A reduction in surface porosity and roughness was demonstrated, as well as the influence of beam energy on the final surface topography.

Ar({}^{\mathbf{+}}\)离子辐照下添加剂材料表面形貌的改变
增材制造(AM)是现代发展中的一组技术,其基础不是材料去除,而是根据 CAD(计算机辅助设计)模型逐层生长和合成物体。AM 技术制造的物体的主要缺点是孔隙率高和表面粗糙。本研究探讨了用能量范围为 2 到 9 千伏的 Ar({}^{+})离子照射添加剂材料 Ti\({}^{6}\)Al\({}^{4}\)V 和 AlSi\({}^{10}\)Mg 表面的可能性。在辐照和机械抛光前后,使用扫描电子显微镜获得了表面形貌。结果表明,表面孔隙率和粗糙度都有所降低,而且束流能量对最终表面形貌也有影响。
