Influence of cleaning process on mechanical properties and surface characteristics of selective laser melted Ti6Al4V parts prepared for medical implant applications
Source abstract
Abstract
Thanks to the recent improvements in additive manufacturing, patient-specific titanium implants have attracted increasing attention because of their unique features and advantages. The aim of this paper is to investigate the effect of a routine cleaning process, usually applied for medical Ti6Al4V implants before surgery, on fatigue limit, surface roughness, and surface chemical composition of Ti6Al4V parts manufactured by selective laser melting. Before cleaning, glass bead-blasting and vibratory polishing treatments were performed on the specimens to improve the surface roughness and fatigue limit. The results of the roughness measurement revealed that the cleaning processes reduces the average surface roughness by 14%, fromRa= 2.1 µm toRa= 1.8 µm. Moreover, after cleaning, the weigh percent of the residual elements stuck to the surface during the surface treatments marginally decreased. The fatigue tests results exhibited an average fatigue limit of 473.8 MPa in the cleaned post-processed specimens.Graphical abstract
