Figure 18. SEM images showing cell adhesion after 2 h of culture on bimetal and as-printed Ti-6Al-4V under different heat treatments: (A) as-printed Ti-6Al-4V; (B) As-printed Ti-6Al-4V/Ta; (C) Heat-treated at 550 °C; and (D) heat-treated at 950 °C; (E) Proliferation of MG-63 cells on the bimetals under different heat treatments after 24 h, 72 h, and 120 h of culture (*P < 0.05) (For each condition, five samples were studied). The error bars represent the standard deviation. SEM: Scanning electron microscope.
