Peculiarities of Usage Diamond-Like Carbon Films as Antireflection Coating

24 Tribology of Diamond , Diamond - Like Carbon , and Related Films

Diamond, diamond-like carbon (DLC), and other related materials (i.e., carbon nitride and cubic boron nitride [CBN]) are some of the hardest materials known and offer several other outstanding properties, such as high mechanical strength, chemical inertness, and very attractive friction and wear properties, that make them good prospects for a wide range of tribological applications, including r...

Cryogenic vacuum tribology of diamond and diamond-like carbon films

Friction measurements have been performed on microcrystalline, ultrananocrystalline, and diamond-like carbon DLC films with natural diamond counterfaces in the temperature range of 8 K to room temperature. All films exhibit low friction 0.1 in air at room temperature. In ultrahigh vacuum, microcrystalline diamond quickly wears into a high friction state 0.6 , which is independent of temperature...

Diamond, Diamond-Like Carbon (DLC) and Diamond-Like Nanocomposite (DLN) Thin Films for MEMS Applications

The Wear Resistance of Cryogenically Treated Diamond-Like Carbon Films

This study explored the effects of cryogenic treatment on the microstructure, hardness, and wear-resistance of diamond-like carbon (DLC) by cryogenically treating NAK 80 mold steel coated with DLC. Raman spectroscopy analyzed the structure of the DLC film. Nanoindenter analyzed the hardness and Young’s modulus of the film, and their relationship determined the wear resistance. Wear test assesse...

Hemocompatibility of surface-modified, silicon-incorporated, diamond-like carbon films.

The hemocompatibility of plasma-treated, silicon-incorporated, diamond-like carbon (Si-DLC) films was investigated. Si-DLC films with a Si concentration of 2at.% were prepared on Si (100) or Nitinol substrates using a capacitively coupled radiofrequency plasma-assisted chemical vapor deposition method using a mixed gas of benzene (C(6)H(6)) and diluted silane (SiH(4):H(2)=10:90). The Si-DLC fil...
