Embodiment Construction

[0023] The technical solution of the present invention is fundamentally different from the prior art providing coatings with high wear resistance and adhesion resistance, while supporting the maintenance of the strength characteristics of precision components operating at high speeds, the relative Motion and substantial axial loading of the disc.

[0024] The technical solution proposed by the invention is applicable industrially and implemented in the form of coating Avinit C310-n1 using equipment made under modern production conditions.

[0025] Table 1 shows the characteristics of the coating applied to the steel sample 8X4B9Φ2-Ш.

Abstract

The invention relates to precision wear-resistant anti-friction coatings produced by means of vacuum-arc deposition, and can be used in mechanical engineering and aircraft engineering when creating designs having enhanced anti-corrosion, anti-friction and protective properties. A coating contains a nitrided layer, a first layer of titanium, a second layer in the form of alternating nano-layers of titanium and titanium nitride, a third layer in the form of alternating nano-layers of titanium nitride and aluminum nitride, and a fourth layer of aluminum nitride. The claimed anti-friction coating provides a high level of operational reliability of assemblies having serialized and novel designs, and increases the service life thereof by 5-20 times.

Description

technical field [0001] The invention relates to a high-precision anti-friction and wear-resistant coating obtained by vacuum arc coating, and can be used in mechanical engineering, aircraft, to establish designs with high anti-corrosion, anti-friction and protection properties. Background technique [0002] One of the most critical elements of pumps widely used in fuel supply units and aeroengine controls, especially pumps HP180 and HT40, is the distribution slide valve (on a pair basis - individually). Flat distributed valves separate the pump suction and discharge cavities. Through the working surface coil, the hardness obtained by nitriding hardening is ≥770HV, so that the bronze pumping unit slides to provide the required pressure for the fuel supply pump. [0003] In order to ensure the efficiency of the pump face coils, the pumping unit was manufactured with a non-planarity < 0.001 mm and a surface roughness Ra = 0.08. [0004] The friction pair mentioned above op...
