"We have increased nearly 30% the lift power and drag power factors in the
laboratory stage which means that we have boosted efficiency of planes 30% in
the lab," Seyed Farshid Chini, the executor of the plan, said on Monday.
"We have increased efficiency of the planes by reducing friction, using nano-coatings,"
he added.
Chini explained that he and his team had a visit to the Airbus research center
in France to talk about the project a month ago, noting that a delegation from
France will travel to Iran in the fall to continue research.
"Based on a contract with Airbus, we will test our studies at a larger scale,"
he added.
The Iranian researchers from University of Tehran had also earlier proposed
biocompatible anticorrosive coatings with nanometric thickness to increase
corrosion resistance in metallic structures in various fields, including
petroleum, gas, petrochemical, automobile fabrication and marine industries.
Chromate coatings are highly toxic despite their desirable anticorrosive
performance and provision of good cohesion for the next coating. Therefore, many
studies have so far been carried out on the finding of a biocompatible
replacement. One of the proposals is the use of silane based coatings that is
placed on the metallic substrate as lining. The aim of the research was to
improve the protective performance of silane coating as a lining coating.
The produced coating provides desirable resistance against corrosion and
increases cohesion for the next coating (such as paint). Therefore, it can be
used in various industries for the production of structures and increasing their
lifetimes. For instance, mention can be made of application of the coating in
automobile fabrication industries, piers, and petroleum and gas industries that
deal with oil and gas pipelines.
According to Najmeh Assadi, one of the researchers, the project has the
potential to be commercialized because the coating has been carried out through
the simple sol-gel method and it is a biocompatible coating.
Despite its very thin thickness at about 250 nm, the coating is able to act as a
physical block against aggressive agents and their movement to the metallic
substrate. On the other hand, the properties have been improved due to the
addition of clay sheet-like Nan particles to the coating.
