“…The composite obtained in the mixed gas of Ar + N 2 possessed a low water contact angle (31.9°), basically in agreement with the findings in relevant studies . This result partially confirmed the good biocompatibility of TiN . In addition, because the nitrided surface could improve the adhesion of fibroblast cells, the composite had the potential to be used as an implant material with better hydrophilcity than that obtained in pure Ar.…”

For the other atmospheres, the introduction of CO and H 2 resulted in even lower angles (15.1 and 24.6°, respectively).…”

The effect of atmosphere on the fabrication of boronized Ti6Al4V/hydroxyapatite (HA) composites was investigated by microwave sintering of the mixture of Ti6Al4V alloy, HA, and TiB 2 powders at 1050 °C for 30 min in the mixed gases of Ar + N 2 , Ar + CO, and Ar + H 2 , respectively. The presence of N 2 , CO, and H 2 in the atmosphere caused formations of TiN, TiC, and TiH 2 in the composites, respectively, together with evident microstructural changes that determined the mechanical properties (compressive strength, compressive modulus, and Vickers microhardness) and wettabilities of the composites after sintering. It was found that the composite exhibited the best mechanical performance with compressive strength of 148.59 MPa, compressive modulus of 13.9 GPa, and Vickers microhardness of 300.39 HV by microwave sintering in the mixed gas of Ar + H 2 , followed by those obtained in the mixed gases of Ar + N 2 and Ar + CO. All of the composites possessed desirable wettabilities, irrespective of the sintering atmosphere, as demonstrated by their very low water contact angles (≤31.9°). The results indicated that it is critical to control the extents of nitration and carbonization for maintaining the performance of the composites, especially the mechanical properties, whereas there is no strict requirement for the same objective using the mixed gas of Ar + H 2 in which qualified composites could be obtained for implant applications.
