In that for the 50C-PEEK, a peak about 32was detected, but the peak around 26was not distinguishable. It was considered that this was since the peak about 256derived in the 50C-PEEK substrate overlapped with the peak around 26attributed to hydroxyapatite.Supplies 2021, 14,eight ofOn the other hand, flake-like crystallites characteristic to apatite formed within the SBF were observed in the surfaces of Sample SPA just after immersion for 1 day.
