Surface-Engineered Epoxy Composite
Coatings for Aeronautic Environments
This Contaminant Adhesion Mitigating Epoxy Composite Coatings
for Aeronautic Environments is a copolymeric epoxy coating
that is loaded with a fluorinated aliphatic chemical species and
nano- to microscale particle fillers. The coating was developed as a
hydrophobic and non-wetting coating for aerodynamic surfaces to
prevent accumulation of insect strike remains that can lead to natural
laminar flow disruption and aerodynamic inefficiencies. The coating
achieves hydrophobicity in two ways. First, the fluorinated aliphatic
chemical species are hydrophobic surface modification additives that
preferentially migrate to the polymer surface that is exposed to air.
Secondly, the incorporation of particle fillers produces a micro-textured
surface that displays excellent resistance to wetting. Combined, these
two factors increase hydrophobicity and can also be used to readily
generate superhydrophobic surfaces.
GENERAL MOTORS RESEARCH & DEVELOPMENT
Remote Laser Welding System
Zinc-coated steels provide excellent corrosion resistance and improved
formability, which are widely used in the automotive industry. The
challenges for application of zinc-coated steels are the corresponding
welding issues. The common way they’re used in the automotive
industry is resistance spot welding (RSW). When RSW of the zinc
coated steels, the selection of the weld guns and electrodes are
dependent on the materials gauges and grades. The Direct Remote
Laser Welding Process and System is a remote laser welding system
that produces high-integrity welds in coated steels such as zinc coated
steels rapidly, by translating the laser beam on the fly with specific beam
travel patterns in order to produce the welds with different shapes such
as spot, stich, oval or staple. Compared to RSW, laser welding is a single-sided process. However, it is significant challenge to laser weld zinc
coated steels in zero-gap lap joint configuration. The highly-pressurized
zinc vapor is produced during the welding process because the zinc has
lower boiling point (906 Celsius degree) than the melting point of steel
(more than 1300 Celsius degree).

Surface Finishing of Niobium SRF Cavities
The patented FARADAYIC HF-FREE ElectroPolishing process is
directed toward surface finishing of niobium superconducting radio
frequency (SRF) cavities. Due to the properties inherent in niobium, it is
the most widely-used material for SRF cavity preparation. The attractive
low-loss property of high-field radio frequency superconductivity
is a nanoscale near-surface phenomenon. Maximizing the useful
accelerating electric fields in these structures requires minimizing local
microscopic enhancements of the surface magnetic field. Consequently,
the interior surface of niobium cavities must be extremely smooth in
order to achieve optimal cavity performance. In contrast to conventional
electropolishing based on direct current (or voltage) electric fields, the
FARADAYIC HF-FREE ElectroPolishing process is based on pulse
reverse or “bipolar” electric fields. In the pulse reverse current process,
an anodic or forward current pulse is followed by an off-time, which is
followed by a cathodic or reverse pulse.
FLSMIDTH USA INC.
Metal Process Technology
The upper layers of copper ore deposits are easily processed using
hydrometallurgical leach technology, in tandem with solvent extraction
and electrowinning to produce high-purity copper metal (i.e., 99.99+
percent) for use in a wide variety of electrical & electronics applications.
The most abundant copper mineral, however, is chalcopyrite (CuFeS2)—a
refractory semi-conductor mineral that is found deeper in the mine.
Consequently, hydrometallurgical copper producers struggle to maintain
metal production during the later stages of mine development. While
existing hydrometallurgical processes are able to recover up to 95
percent of copper from certain refractory minerals, these processes are
complicated, energy intensive and slow. The FLSmidth ROL Process
technology enables the leaching of 97 to 99 percent of copper from
mineral concentrates containing as little as 5 percent copper in less than
six hours; a faster and much more simple process that saves energy and
significantly improves sustainability of existing mines. The process
technology enables current producers to remain productive, thereby
extending natural resources, jobs and utilization of existing processing
infrastructure. In addition to primary metal production, the process
technology more efficiently recovers metals from waste recycle streams.
BLACKTRACE HOLDINGS LTD.
Fabricating Prototypes in an Efficient,
Fabrication techniques in the fluidic/microfluidic industry are too slow
and expensive for a prototyping approach. There is a clear market need for
a device able to fabricate prototypes in an efficient, cost-effective manner.
The Fluidic Factory is the first commercially available 3D printer able to
reliably fabricate custom-made fluidically sealed devices. This is done in
an extremely fast, user-friendly manner. Unlike any other 3D printer on
the market, Fluidic Factory has been custom designed from scratch with
the aim of ensuring the production of milli- and micro- fluidic devices
able to contain fluidically sealed features. All other 3D printers focus on
creating well-defined external shapes and give secondary importance to
inner parts. Contrarily, the Fluidic Factory gives primary importance to
inner features and ensures that any embedded channel is fluidically sealed.
