Abstract

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.
