The almost super-hydrophobic nanostructure AlN anti-reflective layer can effectively enhance light absorption and prevent surface contamination of Al–AlN absorber coatings.

We proposed a superlubricity mechanism of hydrogenated carbon films based on surface hydrogen bonds. Theoretical calculations indicating the proposed is reasonable.

Unprecedented anticorrosive Al–AlNxOy selective solar absorption coatings (SSACs) are fabricated on an industrial scale via a self-developed air-to-air continuous sputtering technique.

Using a simple electrochemical depositing process, iron and cobalt-doped diamond-like carbon (DLC) films were deposited on Si (100) substrates. The results showed that metallic elements were inhomogeneously doped into highly cross-linking amorphous carbon matrix, forming the typical nanocrystalline/amorphous nanocomposite structure, and simultaneously the microsturcture of amorphous carbon was changed by the doping of metals. Field emission performance showed that the incorporation of iron and cobalt effectively decreases the threshold field from 13.5 V/mm to 8.0 V/mm and 6.5 V/mm, respectively, and a highest current density of the Co-DLC film was about 1.2 mA/cm 2 at the electric field of 23.5 V/mm.

A–C:H (hydrogenated amorphous carbon) films were deposited by pulsed direct‐current (d.c.) plasma enhanced chemical vapor deposition on silicon substrates. This study investigated the structural and mechanical evolution of the as‐deposited films with fullerene‐like nanostructure. The results showed that pulsed d.c. negative bias (−500 ~ −1000 V) signally influenced the growth rate, hardness, surface roughness, sp3 content, and friction behavior of the films. As the pulsed d.c. negative bias voltage increased, the sp3 content, surface roughness, hydrogen content and the friction coefficient of the films decreased; however, the growth rate and the hardness increased. The films deposited at −1000 V with fullerene‐like microstructure display a nanohardness of about 19.7 GPa and the smallest friction coefficient (~0.06). The evolution on mechanical and structural properties of the films are explained by the a–C:H growth mechanism based on the interaction on plasma‐surface interface and the subsurface reactions in the film.

The spontaneously self-organizing multilayered graphite-like carbon (denoted as GLC) /TiC films with various bilayer periods in the range of 13.3–17.5 nm were deposited on silicon and 1Cr18Mn8Ni5N stainless steel substrates using closed field magnetron sputtering deposition facility. The microstructures and chemical compositions of the prepared multilayered films were characterized by scanning electron microscopy, high resolution transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy respectively. The self-organizing multilayered structures in all of the films consisted of titanium carbide layers and sp2-rich carbon layers periodically alternate arrangement. The TiC contents and bilayer periods of the multilayered films can be controlled by means of adjusting of sputtering current of graphite target. Furthermore, the mechanical and tribological performances of the prepared films were appraised by nano-indentor, scratch measures, and ball-on-plate tribometer respectively. The results indicated that multilayer structure endowed the as-deposited TiC/GLC films outstanding mechanical and tribological properties, especially the multilayer film with 15.9 nm bilayer period deposited at 10 A sputtering current showed the excellent adhesion strength and hardness; Simultaneously it also exhibited the lowest average friction coefficient in the humid environment owing to its high content of sp2 hybrid carbon.
