Abstract

Hydrophobic stainless steel (SS) is of particular interest for high-value applications, such as aeronautics or food industry. The present pioneering work aims at fabricating an intrinsic bio-inspired microtextured SS by combining vat photopolymerization (VPP) and vacuum casting. SS casting for under millimetric details constitutes a technical challenge due to the high surface tension, high dynamic viscosity and high working temperature of SS (1600 °C). Various microtextured surfaces inspired from natural shapes (fish scales, drops, honeycomb, etc.) were prototyped and successfully fabricated. A dendritic microstructure was formed during the solidification, that, combined with the microtextures, provides a highly hydrophobic SS, with a water contact angle of 120°. Finally, the SS used for casting was outsourced from laboratory waste, making the SS 100 % recycled, which is beneficial from an environmental point of view.

生物灵感和回收316 L不锈钢表面原型通过耦合还原光聚合和投资真空铸造

疏水性不锈钢（SS）是高价值应用，如航空或食品工业特别感兴趣。目前的开创性工作旨在通过还原光聚合（VPP）和真空铸造相结合来制造一种内在的仿生微纹理SS。由于SS的高表面张力、高动态粘度和高工作温度（1600°C），毫米以下细节的SS铸件构成了技术挑战。各种微纹理表面的灵感来自自然形状（鱼鳞，水滴，蜂窝等）的原型和成功制造。在凝固过程中形成树枝状组织，与微观织构结合，形成高度疏水的SS，水接触角为120°。最后，用于铸造的SS从实验室废物中外包，使SS 100%回收，这从环境的角度来看是有益的。

期刊介绍： The aim of the Journal of Manufacturing Processes (JMP) is to exchange current and future directions of manufacturing processes research, development and implementation, and to publish archival scholarly literature with a view to advancing state-of-the-art manufacturing processes and encouraging innovation for developing new and efficient processes. The journal will also publish from other research communities for rapid communication of innovative new concepts. Special-topic issues on emerging technologies and invited papers will also be published.
