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 remodeling implant infections caused by deficient osteointegration. To improve osteogenesis, the Ti treated acid-etching. This study focused on effect surface treatment different percentages sulfuric acid (H2SO4), hydrochloric (HCL), hydrofluoric (HF) SLM Ti–6Al–4V. The microstructure topography before after were evaluated. Then, presence thicker anatase layer that was detectable also observed X-ray diffraction (XRD). apatite-forming capabilities which indicated sample bioactivity assessed in simulated body fluid (SBF) periods 3 days 7 days. apatite formed XRD scanning revealed deposition Ca/P, suggesting successful bone-like apatite. discovered these improvements appropriate prior to clinical applications likely yield higher levels osseointegration.
