Surface enhancement of Ti-6Al-4V fabricated by selective laser melting on bone-like apatite formation

Medical grade Ti–6Al–4V implants fabricated using selective laser melting (SLM) are recognized as a commercial biomaterial used for bone repairs and fracture fixation. However, there have been cases of failed bone remodeling and implant infections caused by deficient osteointegration. To improve ost...
