The tribological properties and preosteoblast behavior of an RF magnetron-sputtered amorphous carbon coating on a Si (100) substrate were evaluated. The graphite target power was varied from 200 to 500 W to obtain various coating structures. The amorphous nature of the coatings was confirmed via Raman analysis. The contact angle also increased from...

... atomic force microscope (Seiko SPA400) was used to measure the surface topographic parameters. The surface topography of a-C coatings with different target powers are shown in Figure 2. The average roughness of the coating was found to increase with the increase in the graphite target power. ...

Superhydrophobic coating ice suppression is an advanced and durable technology that shows great potential for application on pavements. Although many researchers have conducted experimental and theoretical validations to confirm the effectiveness of superhydrophobic surfaces in actively suppressing ice formation, there are still some who remain ske...
