[...] To gain further insights into these effects, we performed reactive molecular dynamics (RMD) simulations with hybrid TTM-MD to understand the effect of early oxidation on wettability of laser-treated titanium (Ti) (fig. 1). Fig 1. [...] Wettability of Ti (without laser) Fig. [...] 5 Wettability of Ti (with laser) Fig. [...] 3 (a) RDF of Ti (with and without laser) and (b) Thickness of oxide film on Ti 4.0 Discussion 5.0 Conclusion Fig 2. [...] wettability of laser-treated titanium (a) (b) MD-TTM Model We used hybrid approach that combines traditional molecular dynamics (MD) with a two- temperature and molecular dynamics (TTM-MD) model for the interaction between ultrafast laser and Ti. [...] References The obtained results show that the femtosecond laser significantly change the structure of Ti as shown in fig.3a. [...] Hence, the TiOx layer grows more quickly in the early stages (0–130 ps) than it does in the later stages (130–300 ps). This condition is brought on by an increase in the TiOx layer and a decrease in O2 diffusion, which thus, affects the wettability of Ti (fig4 and 5). [...] Based on this, our calculation sheds light on how the surface wettability of laser-treated materials alternate. [...] The calculated dynamics of the early titanium oxidation correlate.
