Own Production

The spraying area of NPO «DONTECHCENTER» LLC carries out a wide range of restoration and manufacturing works using modern thermal spraying technologies.

Scope of Works

• Restoration of mounting seats:
- • For bearings and gland seals
• Restoration of housings:
- • For pumps and actuators
• Manufacturing and restoration of babbitt bearings
• Spraying of materials:
- • Bronze, aluminum, babbitt, steel, ceramics and others
• Application of a babbitt layer in a cold plasma environment
• Spraying of various materials:
- • Wire, powder and cord materials

Advantages of Spraying Technology

• Avoids overheating of the part, thermal corrosion and metal mixing, unlike traditional surfacing
• Allows gas-powder surfacing to protect surfaces and create wear-resistant coatings

Restoration of Ship Mechanism Components

We carry out restoration of housings, shafts and bearings using powder spraying in a cold plasma environment.

Bearing machining

Repair of Ship Equipment

During operation, ship equipment is subject to wear, especially in heavily loaded areas. Our specialists restore the geometry and seats using thermal spraying, reducing costs and avoiding the need to purchase new equipment.

Restoration Services

• Restoration of plain bearings with babbitt joints of all sizes, including bronze-based
• Restoration of seats using reinforcing materials
• Restoration of surface geometry with customized mechanical properties
• Application of anti-corrosion coatings

Advantages Over Traditional Surfacing

• No mixing between base and applied material
• Low process temperature avoids deformation
• No pores or inhomogeneities in restored surfaces

Example: Sliding Bearing Restoration

Our specialists have mastered the full cycle of bearing restoration for SKODA and SKL engines (main, crankshaft, camshaft).

Additional Services

• Restoration of pump housings (bronze and other materials)
• Restoration of jack rods
• Application of ceramic coating to shaft journals at seal contact points — significantly extends shaft service life
