Finally a dense (5 to 10 [micro]m thick) pyrolytic carbon
coating is deposited upon the carbide shell at 1300[degrees]C in a 0.4% propane-butane argon mixture.
Based on the FID response and laser-transmission data, the amounts of organic, elemental, and pyrolytic carbon
are then calculated for the sample.
This method uses pyrolytic carbon
planchets (available from electron microscopy suppliers) as specimen mounts.
* the decomposition of the foam pattern in casting ferrous alloys resulting in the formation of solid pyrolytic carbon
Therefore, this tar was anticipated to be able to decompose into a large amount of pyrolytic carbon
or secondary char, as compared to tar produced at other temperatures.
In the fuel element of HTR-PM, [sup.60]Co in porous pyrolytic carbon
(buffer layer) and dense inner pyrolytic carbon
(IPyC) of TRISO fuel particle will diffuse and interact with silicon carbide (SiC) of TRISO fuel particle , which is considered to possibly influence the performance of SiC.
The ORNL technique uses a proprietary pretreatment to recover pyrolytic carbon
black material, which is similar to graphite but man-made.
 showed that the blood compatibility of TiN films was as good as that of low-temperature isotropic pyrolytic carbon
and the durability of titanium heart valve cages coated with TiN increased seven-fold.
The second, third, and fourth coatings are pyrolytic carbon
, silicon carbide, and pyrolytic carbon
, respectively, all layered to provide radiation, gas, and mass diffusion barriers and to act in concert as a pressure containment vessel.
For Direction I, Zone 1 exhibits a typical microstructure of carbon fibers coated with pyrolytic carbon
is mainly used as an artificial heart valve material because of its good strength, wear resistance and durability, and most importantly, thromboresistance or the ability to resist blood clotting.
The porous preform becomes enveloped in a vapor film that infiltrates it and rapidly deposits pyrolytic carbon
from the inside out.
