FSUE CRIM has a long experience in developing and causing wear-resistant coating on machine elements are working in the oil and aggressive environments with the presence of abrasive.

This technology is a plasma, gas flame, and the supersonic spraying of powder on the basis of alloys from nickel, cobalt, iron, copper, composite materials, oxygen less refractory compounds, etc.

FSUE CRIM has the equipment for spraying, allowing cause surface on the details of various shapes with maximum dimensions Ø Ø 420 mm 2000, including the internal surfaces of parts Ø 60 mm or more. The thickness of coatings 0.3 - 1.0 mm.
Our technologies allow hardening steel and rebuild parts: shafts for various purposes, spindles, place under bearings; internal combustion engine cylinders and compressors: details sealing pumps and gearboxes, plugs oil pumps; knives. screws, working in the abrasive environment, and much more.

Examples of technology gas thermal spraying.

1.Recovering cartridges cylinders of air compressors in railway locomotives.
Restores internal surfaces of cylinders Ø 110, 125 and 150 mm plasma spraying method on the basis of alloys of nickel and iron. Cost recovery 40 - 70% of the cost of new parts.
2. Recovering fingers piston air compressors and DVS.
3. Recovering necks sleeve locomotive.



Firmness cover 60 - 62 HRC. Coverage is paired with needles bearing. The cost of restoring 40% of the cost of new parts.
