Formation of diamond-like carbon films and carbon foam by ultrafast laser ablation

Pulsed Laser Deposition of Diamond-like Carbon Thin Films: Ablation Dynamics and Growth

Thin films of diamond-like carbon have been grown by pulsed laser deposition using a Nd:YAG laser at 532 nm. Time-of-flight mass spectroscopy was used to investigate the effects of laser power density and background gas pressure on the plume characteristics including the species in the plume and the kinetic energy distribution of each species. We found that with increasing laser power density (...

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-like Carbon Films Deposited by Hydrocarbon Plasma Sources

Diamond-like carbon deposition techniques, characterization techniques and processing parameters, such as gas ratio, bias voltage, gas pressure, type of precursor gas used, temperature, gas total flow, substrate material, among others are reviewed. Mostly silicon substrates have been employed, but also metallic materials such as titanium and aluminum alloys or steels have been used as well. Imp...
