© с сайта ТГУ TOMSK, Mar 16 – RIA Tomsk. Scientists of Tomsk State University (TSU) developed a specialized
coating, due to which it is possible to reduce the weight of aircrafts by 30
percent or more, the press service of the university reported on Thursday.
Chemists under the leadership of professor Anatoly Mamayev work on the
project. For the production of aircraft details scientists suggest to use
magnesium alloys with a special ceramic coating which was created at the LLC
SibSpark enterprise (enters the TSU innovative belt). Work was conducted within
the framework of the the federal target program under agreements with the JSC
Information Satellite Systems named after academician Reshetnev.
"Now alloys on the basis of aluminum are generally used. However the
weight of magnesium is almost twice less. Unfortunately, magnesium – is frail
material, it is not used in itself. But it can be used together with special
coatings which will provide high wear resistance and the required hardness of
details from magnesium alloys ", – Mamaev is quoted in the message.

It is specified that the created technology has no analogs in Russia. By
calculations of scientists, use of a special covering will allow to reduce the
weight of planes and satellites by 30% and even more. It, respectively, will
lead to economy on fuel for aircraft.
It is explained that the scientific group of professor Mamayev is engaged
in creation of nonmetallic inorganic coverings on border of two environments –
metals or metal and liquid. Under the influence of the high-energy stream
(plasma) chemical bonds on borders are broken, and new substance with unique
properties is synthesized. The received nanostructural coverings are oxidic,
carbide or nitride connections.
"Accreting with the surface of one of environments, they become a
peculiar armor for a metal product – don't exfoliate, have very high durability
at deformation and thermal stability. The technology developed by TSU
scientists allows to change functional properties of materials and to receive
coverings with specified properties which can be used not only in astronautics
and aviation, but also in the automotive industry, construction", – is
said in the message.
