“…Diamond-like carbon (DLC) coatings are widely used in aerospace [1], automotive [2], defence [3], food and beverage [4], electronics [5], mechanical [6], biomedical [7], surface cosmetics [8] and digital [9] industries. Their recognition in this broad range of industries is due to their superior and multifunctional features.…”

“…However, some moving implants, such as joints, serve in environments where corrosion and wear coexist, requiring that the protective film possesses a lubrication effect. It is well-known that diamond-like carbon films are promising protective films with high hardness, low friction coefficient, high chemical inertness, high corrosion resistance, and good biocompatibility. − However, the friction coefficient of a pure hydrogenated amorphous carbon film is close to 0.25 and its wear rate is on the order of 10 –6 mm 3 ·N –1 ·m –1 , which makes it difficult to meet the needs of permanent implants. , Element doping is a recognized method of improving the tribological properties and corrosion resistance of DLC films. − Nevertheless, the introduction of different doping elements is bound to change the physical and chemical properties of the DLC film surface, thus affecting its biocompatibility. For example, F&H-DLC has been reported to exhibit strong antibacterial properties .…”

Ti6Al4V artificial implants are increasingly demanded for addressing human dysfunction caused by an aging population and major diseases. However, they are restricted due to the release of vanadium and aluminum ions in the process of corrosion and wear. This work is aimed to provide a protective film for Ti6Al4V artificial implants, and then, a Si-incorporated diamond-like carbon (Si-DLC) film and Si-and N-incorporated DLC (SiN-DLC) film were deposited on the surface of Ti6Al4V by plasma-enhanced chemical vapor deposition. Results suggest that the thickness of the as-deposited DLC film is approximately 2 μm, and the SiN-DLC film shows the lowest surface roughness (53.0 ± 3.6 nm) compared with the Ti6Al4V and DLC films. The above DLC film possesses high mechanical properties compared with Ti6Al4V, and the SiN-DLC film shows the best resistance to plastic deformation. In addition, the DLC film exhibits high adhesive strength (>13 N) with Ti6Al4V, which is a prerequisite for service in liquid environments. Whether in SBF solution or SBF + BSA solution, the friction coefficient and wear rate of the above DLC film are much lower than those of Ti6Al4V, and the SiN-DLC film displays the optimal tribological properties (0.072 and 1.82 × 10 −7 mm 3 •N −1 •m −1 , respectively). Moreover, Si-DLC and SiN-DLC films possess similar corrosion resistance but are far better than Ti6Al4V. Cytotoxicity test results show that the SiN-DLC film can significantly improve cell viability and promote cell proliferation to a certain extent. Consequently, the SiN-DLC film is a protective film with more potential for artificial implants.

“…Stephen Brown et al [113] developed a two-coated superhydrophobic system. The superhydrophobic surface was obtained by suspending a plasma sprayed TiO 2 layer and chemical vapor deposition of a coating containing SiN X layer, DLC:SiO X layer and PP-HMDSO layer.…”

Researches on superhydrophobicity have been overwhelming and have shown great advantages in various fields. However, the abrasion resistance of superhydrophobic structures was usually poor, and they were easily damaged by external force or harsh environment, which greatly limited the applications of superhydrophobic surfaces. Much attention has been paid to improving the abrasion resistance of superhydrophobic materials by researchers. In this review, aimed at the advances on improving the abrasion resistance of superhydrophobic surfaces, it was summarized and compared three enhancement strategies including the reasonably design of micro‐nano structures, the adoption of adhesives, and the preparation of self‐healing surface. Finally, the applications of typical superhydrophobic materials with abrasion resistance were reviewed in various fields. In order to broaden the application fields of superhydrophobic materials, the abarasion resistance should be further improved. Therefore, we proposed the ideas for the future development of superhydrophobic materials with higher abrasion resistance. We hope that this review will provide a new approach to the preparation and development of stable superhydrophobic surfaces with higher abrasion resistance.
