研究目的
To explore a more robust industrial method for the creation of super-hydrophobic surfaces using a fibre based nanosecond pulsed laser to process polished Ti6Al4V samples.
研究成果
A nanosecond pulsed laser was successfully used to create a superhydrophobic surface on Ti6Al4V, with thermal post-treatment reducing the time needed to achieve the superhydrophobic effect. The contact angle measurement technique influenced the evolution of the contact angle, but the thermal treatment improved stabilization. The microstructure's characteristics significantly affected the contact angle achieved, with pillar-based topography being most effective for a superhydrophobic regime at specific fluences.
研究不足
The study is limited to Ti6Al4V samples and the effects of nanosecond laser texturing combined with thermal post-processing. The influence of measurement frequency on contact angle development was noted as a potential limitation.
