Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Metallographic examination of improved structures of Avinit С multilayer nitride-based coatings, particularly
coatings of Ti-Al-N system and Mo-N system-based coating have been carried out. Use of
effective methods of surface cleaning and three-level arc control system in the techniques under development
for prevention of surface damaging, caused by micro arcs, allows to apply coatings of precision
and high finish class surfaces up to 12 – 13 grade of finish without deterioration of surface
finish class. The experimental findings confirm a possibility of low-temperature deposition of very
hard Avinit С coatings based on nitrides of metals under the conditions providing good adhesion to
the parent material (steel DIN 1.2379 (Х12Ф1) without decrease in strength properties of the steel
(<200 °C) and without distortion of the coated surfaces.
Tribological examination of advanced constructions of multicomponent multilayer Avinit coatings
under aviation fuel ТS-1 for the purpose of selection of coating materials for friction parts of precision
couples used in aggregate building. Deposition of coatings effectively raises durability of friction pairs
to scoring. Advanced coatings have low friction coefficients (0.75 − 0.095) at loadings up to 2.0 kN
and have shown high wear resistance.
The received results allow to develop software products for obtaining of multicomponent multilayer
coatings of required composition using Avinit equipment and tryout stable techniques for deposition
of functional coatings to be used in friction parts of precision couples of standard aircraft units. |
