Behaviour of MoDTC in DLC/DLC and DLC/steel contacts
Tribology International, 2012Abstract Diamond-like carbon (DLC) coatings are beginning to be used on machine components parts because of their excellent friction and wear resistance properties. It is hence important to be able to formulate lubricants able to work effectively with these coatings.

Friction properties of DLC/DLC contacts in base oil
Tribology International, 2011Diamond-like carbon (DLC) coatings are promising surface coatings in terms of friction and wear performance and are beginning to be introduced in internal combustion engines, mainly because of the need to reduce friction and because of compositional constraints on engine lubricants.

A DLC/W-DLC multilayered structure for strain sensing applications
Diamond and Related Materials, 2008The strain dependence in tungsten-containing diamond-like carbon (W-DLC) film was investigated. The W-DLC film was deposited onto Si substrate by plasma enhanced chemical vapor deposition and DC magnetron co-sputtering of tungsten metal target. The strain dependence of resistance was measured by four-point bending test under well controlled temperature

Adhesion Study of Dlc/Cr/Dlc and Dlc/Ti/Dlc Sandwich Structures on Hardened Steel
MRS Proceedings, 1996AbstractHard amorphous hydrogenated carbon, also referred to as diamond-like carbon films, are of technological interest as protection coatings due to their special properties such as high hardness, low friction, low wear, chemical inertness and electrical insulation. In this paper a study of the adhesion properties of multilayer structures composed of

This paper presents a novel approach to proving the full Birch and Swinnerton-Dyer conjecture for all elliptic curves over the rational numbers. The proof synthesizes previous foundational work with a new computational technique called "synergy-lift" to resolve the remaining open questions.

Journal of Receptors and Signal Transduction, 2013
RhoGTPases are defined as a family of 20 small G proteins playing important roles in almost every cellular process. RhoGTPases are guanine nucleotide-binding proteins existing in two forms: the active form which is GTP bound and the inactive one that being GDP bound.

Comparison of DLC and N-Doped DLC Synthesized by RF-PECVD
Advanced Materials Research, 2014Diamond-like carbon (DLC) films and nitrogen doped DLC (NDLC) were deposited on glass slide and H13 steel by plasma-enhanced chemical vapor deposition using a commercial RF 13.56 MHz (RF-PECVD). The films have been prepared from CH4 for DLC and CH4+N2 mixtures for NDLC. The deposition process was at 300°C under argon atmosphere for 120 min.

Tribological properties of multilayer DLC/W-DLC films on Si
Thin Solid Films, 2008Abstract Multilayer films of diamond-like carbon (DLC) and tungsten-containing diamond-like carbon (W-DLC) films were deposited onto silicon wafers using radio frequency chemical vapor deposition (RFCVD) and a magnetron sputtering method. The W-DLC layer was deposited on the silicon wafer with less than 60 W magnetron output.

Influence of parameters on Al/Ti-DLC/DLC selective absorber film
Surface Engineering, 2017This work explores the effects of target current and argon gas flow on structural and optical properties of Al/Ti-DLC/DLC selective absorber films used in solar-thermal conversion processes. The transmittance of DLC (diamond-like carbon) anti-reflection layer is affected by the sp 2 -C/sp

Lower Emissions with DLC Coatings
MTZ worldwide, 2009With vehicle production growing annually and pressure on manufacturers to reduce vehicle emissions, innovative methods will have to be found to make engines more efficient. The PSA Group has set up with Bekaert a co operative test programme to measure the impact of Diamond-Like Carbon (DLC) coatings on the frictional behaviour of certain components ...
