Purpose of the development: For coatings on the surfaces of threaded connections, operating under intense wear and mechanical loading.

Recommended application field: The developed compositions of powdered copper-based self-fluxing alloys and their application process used to produce coatings on the surfaces of threaded connections , operating under intense mechanical loading and wear bushings and nuts track machines , nuts bolts valves, sleeves and nuts and hydro - pneumatic equipment . Port and freight nuts machine , technological and other equipment engineering companies , automotive , rail, sanitary and other profile.

Technical characteristic: Specifications: - Increasing the life of friction "screw-nut" - 2.5-3 times - Coefficient of friction - 0.06, 0.007, - Hardness of the coating - 175 - 180 HB - The melting point of the material - 900 - 915 ° C. - The performance of the process - 12 - 7 children / h - Saving ferrous alloys up to 85%.

Advantages over analogues: Used exceeds domestic antifriction powder mixtures and the technology of their application. Exceeds world-class products company "Hoganes" Sweden, "label" U.S. NPK "Cermets" Bulgaria in service life of the friction pair "screw-nut". Composition of powder mixtures, process their application and technological rigging equipment with environmentally safe.

The development stage readiness: Introduced in production

Technical and economic effect: Reducing the cost 1.5-2 times, software failure of supply of similar imported parts, performance improvement process technology 1.5-2 times, increasing the ratio of copper alloys to 0.85. Increased reliability of threaded connections, operating under intense wear and mechanical loading in general.

Description of the development:
()
The developed compositions and process allow to obtain highly reliable parts with anti-friction coatings on the surface of the threaded connections, corresponding to world level for a number of technical and economic parameters. Manufacturing process of powder mixtures and antifriction products introduced, the commercial production of powder mixtures and components with anti-friction coatings. Required investments: 60000 thousand rubles. Payback period: 2 years.
