Materials. Carbon nanotubes (C-grade; multiwall; powder and bulk paper) were purchased from NanoTechLabs, Inc. (Yadkinville, NC). Oxidized CNT (O-CNT) were prepared by sparging O 3 (5 to 10 mg liter −1) into an NaOH solution (pH 10) and filtering the O 3-NaOH solution through CNT buckypaper in a commercial filtration casing (Whatman) while applying an anodic current of 3.2 mA cm −2 (40 mA

diamond-like carbon (DLC) coatings were coined and deposited onto a WC-Co insert using chemical vapour deposition (CVD) methods. DLC coatings were developed by testing the effects of bias voltage, deposition time and gas pressure. During the
Figure 4b shows an electron micrograph of an etched powder particle with an estimated ferritic grain diameter of 3.06 ± 0.45 μm as measured using ImageJ and the line intercept method. Upon
This chapter covers the preparation and properties of ultraviolet (UV)-curable nanocomposite containing carbon nanotubes as fillers. UV-curing technology is of particular interest due to its unique properties such as rapid curing process and solvent-free formulation. Alongside with the advantages of utilizing this curing method, carbon nanotubes undergo benefits including high aspect ratio
The adhesion of the MWCNTs coatings to the Ti surface was determined using the shear test method, according to standard ASTM F-1044-05. These results indied that one type of MWCNTs characterized by a higher concentration of functional groups has better adhesion to …
Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond.DLC is usually applied as coatings to other materials that could benefit from some of those properties. DLC exists in seven different forms. All

Results of investigations into the properties of nanosized carbon coatings doped with nitrogen, tungsten, and aluminium and obtained on silicon by the pulse vacuum arc method are discussed. The doping effect on internal stress values, microhardness, and surface morphology was studied. It has been established that doping nanosized carbon coatings with nitrogen, tungsten, and aluminium makes it
Examples of coatings that may be impacted include, but are not limited to; epoxies, polymethyl-methacrylate (PMMA), polyurethane-methacrylate (PUMA), methyl-methacrylate (MMA), and carbon resin. Note 1: Example —A urethane coating of 20 mil thickness, eedded with 1.2 µm titanium particles resulted in a 2.1 mil loss in coating thickness and 110 mg mass loss.

method marked as MW/RF) was used in order to conduct the modifiion processes using pure methane. Carbon coatings were synthesized using CH 4 atmosphere under the pressure of 100 Pa in 5 min. Negative r.f. bias was equal to 250 V, whereas
The article shows the possibility of applying a silicon dioxide coating on the carbon fiber by the sol-gel method. The evaluation of the protective properties of the obtained coatings at a temperature of 600 C is given; the changing of the a coated fiber surface
The element mapping confirmed homogeneous distribution of carbon in ZnO when using the method of pulsed electron evaporation of powders’ mechanical mixtures. Magnetization of the annealed ZnO sample produced in vacuum is two times higher than magnetization of the annealed sample produced in the air atmosphere due to the higher density of oxygen vacancies in the sample formed in the oxygen
Most hydrogen-free coatings are applied using a method of physical vapor deposition (PVD) by arc evaporation which produces tetrahedral amorphous carbon, or ta-C. With a high level of tetrahedral bonds (mostly 50 to 60 percent), substantially higher abrasive wear resistance is achieved compared to a-C:H alternatives.
Protective nitrogen doped Si-C multilayer coatings on carbon, used to improve the oxidation resistance of carbon, were obtained by Thermionic Vacuum Arc (TVA) method. The initial carbon layer having a thickness of 100nm has been deposed on a silicon substrate in the absence of nitrogen, and then a 3nm Si thin film to cover carbon layer was deposed. Further, seven Si and C layers were
The preparation of TiC coatings was attempted onto pyrolytic carbon substrate by C/Ti interdiffusion. An electron beam melting (EBM) method was used for liquid titanium diffusion. For the solid titanium diffusion, Ti films were produced by electron beam evaporation (EBE). Relatively thick coatings with several micrometers could be prepared by EBM at around 1800°C and thinner coatings with
The carbon coatings of optical fibers are prepared by the thermal chemical vapor deposition using the methane as the precursor gas. The thickness of carbon films at the deposition temperature of 950 C is controlled by the different deposition time.
