What do you need to go faster,
farther and higher? Answer: The right stuff and some new
materials. University of Canterbury-born company Koti
Technology is helping to commercialise a ceramic coating
system that may some day be part of the NASA spacecraft
programme.
Hypersonic vehicles – round the
globe spacecraft - are not yet reality, but traveling at
5-10 times the speed of sound is certainly driving materials
science in extreme new directions. All aircraft need a
paint job, it just turns out this one needs a coating that
can withstand temperatures over 1500C - hot enough to melt
most metals.
University of Canterbury (UC)
associate professor Susan Krumdieck was named as the only
international investigator in the US National Hypersonic
Science Centre (NHSC) because NASA and the US Air Force
Office of Research believed her technology for producing
protective ceramic coatings on complex shaped objects was
the only one in the world that could provide the "sapphire
paint job" which could protect the silicon carbide
composites from the extreme environments of hypersonic
flight.
Koti chief executive Sam Davies Talwar, a
UC graduate, is working with professor Krumdieck and a team
of PhD and undergraduate students to develop commercial
scale systems for this and many other more down to earth
industrial and medical applications.
Aerospace
company Teledyne is managing the consortium including six
top US universities. Over the past month Krumdieck has been
in the USA meeting with other materials scientists and with
the managers of the consortium.
``We had a bit of
a delay with the earthquakes, but it was great to be able to
show the group our first results - the material they wanted,
coating the composite material they provided in a uniform
way with no visible cracks or flaws," Krumdieck said
today.
She is currently at the Colorado School of
Mines, where some material testing of future samples may be
carried out with collaborators.
A team of four
fourth year UC mechanical engineering students have been
working on the project. They had a lot to learn as they and
post doctorate types in physics, chemistry and materials
science are usually the ones doing the research in other
labs that undertake this high-tech research overseas. The
team were able to deposit a layer of alumina (sapphire) on
samples supplied by Teledyne which will be packaged up and
sent for testing this month by other NHSC consortium
members.
``It was really great showing the
scanning electron microscope images of the coatings to the
programme director, and having him really be amazed that the
coating was such high quality - a great achievement for
undergraduate engineers," Krumdieck said.
The
coating process was invented by Krumdieck during her PhD
thesis research in 1999. It has since been developed into a
platform technology with potential applications in
industries such as energy production, electronics, dairy,
aviation, industrial manufacturing, medical devices and
mining.
"The list of companies that have
contacted us wanting a ceramic coating on something is quite
large and growing" Davies Talwar said.
``We are
gearing up to put the alumina and other coating materials
onto samples companies and other research groups have sent
us. In fact we have several summer scholarships on offer and
we are looking for new postgraduate students."
Koti is also working with New Zealand equipment
manufacturer, Buckley Systems in Auckland to build
industrial scale coating machines for customers from around
the
world.
