“…The Ca/P ratio for the hydrothermally treated coating from the present study (1.28) was lower than our previous study (1.71) [ 27 ]. The differences in the power supply system and limited discharge power may be responsible for this.…”

“…The chemical alteration of the coating after the immersion in SBF was evaluated by X-ray photoelectron spectroscopy (XPS, AXIS Ultra XPS spectrometer, KRATOS analytical, Stretford, Manchester, UK). The parameters for XPS were set as in a previous study [ 27 ]; the monochromatic Al K X-ray was at 150 W anode power, survey spectra from 0 to 1200 eV with a pass energy of 80 eV for a survey, and 20 eV for core-level spectra. Two specimens of each group were used for the XPS test.…”

Polyetheretherketone (PEEK) has become an alternative material for orthopaedics and dental implants. However, bio-inertness is an important limitation in this material. In the present study, a hydroxyapatite (HA)–titanium nitride (TiN) coating was fabricated via pulsed DC magnetron sputtering and treated with hydrothermal treatment to improve the bioactive property of PEEK. The dissolution behavior of the coating was studied in simulated body fluid solution (SBF) at 1, 3, 5, 7, 14, 21, 28, and 56 days. The coating surface was analyzed before and after the immersion process by X-ray photoelectron spectroscopy (XPS), atomic force microscope (AFM), and scanning electron microscope (SEM). The calcium and phosphorus concentration alteration in SBF was quantified by an inductively coupled plasma-optical emission spectrometer (ICP-OES). Coating dissolution and the precipitation of calcium phosphate complex from SBF were observed as occurring suddenly and continuously throughout the immersion times. These processes resulted in an alteration in both physical and chemical coating properties. After 56 days, the coating remained on PEEK surfaces and the Ca/P ratio was 1.16. These results indicate that HA-TiN coating via pulsed DC magnetron sputtering followed by hydrothermal treatment improved the bioactivity of materials and provided a potential benefit to orthopedics and dental applications.

“…According to the previous study by Buranapanich et al (2020), the hydrothermal treatment at 100°C for 12 hours was the most favorable condition for improving the HA crystallinity on HA-TiN films. This condition yielded the closest Ca/P ratio to the stoichiometry of HA and did not exceed the glass transition temperature of PEEK (143°C) (Buranapanich et al, 2020). Additionally, the study of Shi et al (2015) suggested performing the hydrothermal treatment for TiN coating with a temperature below 120°C to preserve the hardness of TiN (Shi et al, 2015).…”

“…Therefore, the post -deposition annealing by hydrothermal treatment should be performed so as to crystallize the sputtered films (Ozeki et al, 2003). According to the previous study by Buranapanich et al (2020), the hydrothermal treatment at 100°C for 12 hours was the most favorable condition for improving the HA crystallinity on HA-TiN films.

“…For the long-term application of coated materials in the living body, the optimal and stable adhesion strength of the film and substrate is one of the significant parameters that should be of concerned, so as to obtain a durable boneimplant integration (Ding et al, 1999;Buranapanich et al, 2020). In order to simulate the living body condition, the in vitro test using simulated body fluid (SBF), which has ion concentrations close to human blood plasma (Kokubo and Takadama, 2006), was performed at different immersion periods before testing the bond strength of the film.…”

This study sought to investigate the effect of immersion time in simulated body fluid (SBF) on the adhesion strength of hydrothermally treated hydroxyapatite-titanium nitride (HA-TiN) films on polyetheretherketone (PEEK) substrates. The HA-TiN films were deposited on PEEK substrates via magnetron sputtering and annealed with hydrothermal treatment. The crystalline phase and element compositions on the deposited films were confirmed by X-ray diffractometry (XRD), and X-ray photoelectron spectrometry (XPS). The samples were then immersed in SBF at 37°C for 7 to 56 days, where the surface characterization and chemical composition of the films were analyzed using scanning electron microscopy (SEM), atomic force microscopy (AFM), and XPS. After the in vitro degradation in SBF, the adhesion strength between HA-TiN films and PEEK substrates were measured by a universal testing machine and further investigated the failure mode using a stereomicroscope and SEM. The results demonstrated the improvement of crystallinity on HA-TiN sputtered films after hydrothermal treatment. After immersion in SBF, the coating surface revealed some nucleation without any detachment and exhibited an increase of surface roughness. The hydroxyapatite and titanium dioxide were revealed on the surface throughout the 56 days, while the Ca/P ratio decreased and remained constant during immersion. The adhesion strength did not significantly differ in all groups. These findings concluded that hydrothermally treated HA-TiN sputtered films on PEEK substrates showed the stability of adhesion strength throughout 56 days in simulated physiological conditions. The dissolution and precipitation during immersion represented the favorable characteristics of the films in the orthopedic or dental application.
