Abstract
AbstractThe paper primarily explores the suitability of using Abrasive jet machining (AJM) in fabricating microchannels on Ti-6Al-4V ELI alloy. The work evaluates the microchannels 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 microchannels 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 microchannels with nanolevel surface roughness without the effects of heat-affected zone (HAZ), resolidification, burrs, and particle embedment.
