The optical irradiation with the power density below ~1.5 x [10.sup.8] W/[cm.sup.2] did not initiate phase transformation in the amorphous film
. The nanocrystalline phase started to appear at higher irradiation intensities and the first observed crystals had sizes at the excess of 10 nm.
The temperature zone for constant-temperature embossing is selected in accordance with the region where the amorphous film
crystallizes when heated above its [T.sub.g].
Figure 4 shows some examples for SEM images of films with an amorphous film
Figure 4(a) and films with crystalline structure Figures 4(b) and 4(c).
(9) worked on [Al.sub.2][O.sub.3] films deposited by reactive MS, resulting in an amorphous film
and the formation of nanocrystals of [gamma]-[Al.sub.2][O.sub.3] being embedded in the film, which was depending on the substrate temperature and the depositing RF power.
The company said the amorphous film
is typically used in thin-gauge thermoforming.
High-output, water-quenched, downward-extruded bubbles may require different nylon formulations for medical use because an amorphous film
often has more memory and shrinkage around the product being packaged.
This is a thin amorphous film
that can be applied to many, many types of products, including a laminate directly on to a metal roof panel.
(20) In the former case, thickening of the amorphous film
proceeds at both the metal/Film and film/environment interfaces, through co-operative transport of O2- and Al3+ ions across the pre-existing film: for crystalline alumina development at sufficiently elevated temperatures, this usually proceeds below the amorphous film
at sites where molecular oxygen can react with the substrate.
By contrast, the Plasmon WORM disk uses an exceptionally stable amorphous film
in a single layer.
For engines and drivetrains where internal friction affects the wear characteristics of so many parts, Argonne has developed an amorphous film
, called NFC, that's so slick it has a friction coefficient of 0.001.
Preexisting inclusions facilitate crystallization of the amorphous film
by acting as nuclei.
Disruption of molecular regularity by the presence of a small amount of branched hydrocarbon, coinciding at the rubber surface with the arriving alkane, will give an amorphous film
of high density and maximum resistance to gas, i.e.
