| Abstract Scope |
This study evaluates the effects of Copper (Cu) nanopowders and Zinc (Zn) nanopowder-mixed dielectrics in Powder Mixed EDM (PMEDM) on the surface and biological performance of Ti-6Al-4V alloy for orthopedic implant applications. Results suggest, Zn-mixed dielectric yielded higher surface roughness (Ra = 2.8 µm) as compared to Cu (Ra = 2.4 µm), promoting better osteointegration and hardness increased to 430 HV (Cu) and 410 HV (Zn), while Cu-treated surfaces exhibited superior wear resistance (0.92 × 10⁻⁶ mm³/N•m) and lower corrosion current density (1.4 µA/cm²) compared to Zn (1.8 µA/cm²). However, In-vitro cytocompatibility tests showed higher cell viability on Zn-modified surfaces (~93%) in comparison to Cu (~87%). Surface analyses confirmed oxide and phosphate layer formation, enhancing bioactivity. Overall, Zn nanopowder emerges as the superior choice as an additive metallic powder in dielectric due to its balanced enhancement of both biological response as well as acceptable mechanical/corrosion performance, making it more suitable for orthopedic implants requiring biocompatibility and early-stage osseointegration. |
