| Abstract Scope |
Ti-6Al-4V alloys are extensively used as a substitution for human bones as they are biocompatible, lightweight, corrosive resistant, and have low elastic modulus. Additive Manufacturing is the best suitable process for realizing complex biomedical implants of Ti-6Al-4V alloys. However, some implants require a mirror-like polished surface typically obtained through a post-processing technique. Therefore, this work proposed a post-processing method to improve the surface quality of additively manufactured Ti-6Al-4V alloys. Hybrid Electrochemical Assisted Magnetorheological utilizes the synergic action of mechanical abrasion and electrochemical reaction to enhance the surface quality of the parts without affecting their surface topography. However, the H-ECMR finishing process effectively applies to parts with initial Ra in the sub-micron range. Hence, chemical etching is used as an intermediate process after fabricating the femoral head by LPBF to reduce the surface roughness in the sub-micron range. A final surface roughness of 33.14 nm is achieved on the polished surface. |
