摘要

本文主要探讨了磨料射流加工在Ti-6Al-4V ELI合金上制备微通道的适用性。该工作评估了使用工艺参数（如空气压力、进给速率和间隔距离）生成的微通道，以及它们对通道几何形状（如宽度、深度、表面粗糙度和形貌）的影响。由于Ti-6Al-4V ELI合金通常用于生物植入物，因此分别使用固着跌落技术和Chibowski方法测量产生的微通道的接触角和表面自由能，以评估使用AJM创建这种特征的好处，AJM可能在医学领域有应用。结果表明，AJM可以在不受热影响区（HAZ）、再固化、毛刺和颗粒嵌入影响的情况下产生具有纳米级表面粗糙度的亲水性微通道。

Fabrication of Micro-channels On Biomaterial Ti-6Al-4V ELI Using Micro Abrasive Jet Machining

The paper primarily explores the suitability of using Abrasive jet machining (AJM) in fabricating micro-channels on Ti-6Al-4V ELI alloy. The work evaluates the micro-channels generated using process parameters such as air pressure, feed rate, and standoff distance and their effect on channel geometries like width, depth, surface roughness, and topography. Since Ti-6Al-4V ELI alloy is commonly used in bio-implants, the contact angle and surface free energy of generated micro-channels is measured using the sessile drop technique and Chibowski approach, respectively to assess the benefits of creating such features using AJM, which can have probable applications in the medical field. The result indicates that AJM can produce hydrophilic micro-channels with nano-level surface roughness without the effects of heat-affected zone (HAZ), resolidification, burrs, and particle embedment.
