Influence of topography on plasma treated titanium surface wettability

With the aim of studying the topographic influence on wettability of plasma-treated surfaces, we used eighteen commercially pure titanium (CP Titanium) disks (grade II), 10 mm in diameter and 1 mm thick, and in atmospheres of Argon (Ar), Hydrogen H2 and Ar–H2. These samples were submitted to plasma...

Correlation between average roughness (Ra) parameters and the ratio between maximum peak height and average distance between the highest peak and lowest valley (Rp/Rz) and wettability for the different treatment conditions were analyzed. Given the results obtained, it was concluded that Ra and Rp/Rz are not appropriate for correlating with wettability and it is suggested that a new topographic parameter be adopted for the Cassie–Baxter equation.
