XPS analyses of the outermost layer of CpTi (A) and TZP (B). (A) The Ti2p XPS spectrum included 2p1/2 and 2p3/2 electron peaks, which decomposed into Ti0 and Ti4+, indicating the presence of metal and oxide, respectively. (B) The Zr3d XPS spectrum included 3d3/2 and 3d5/2 electron peaks with the presence of oxide (Zr4+). The O1s spectra of both CpTi and TZP have two peaks defined as TiO2 (ZrO2) at ~530.0 eV and OH at ~532.5 eV.
