Marine engines and auxiliary systems operate in some of the toughest environments on Earth. Turbochargers and steam turbines on ships are constantly exposed to high rotational speeds, exhaust gas corrosion, salt-laden humidity, and wear from carbon residue.Over time, these conditions cause critical components—like rotor shafts, turbine journals, compressor wheels, and labyrinth seals—to degrade, reducing efficiency and risking engine failure.
At INJEGOV SA, we use advanced laser cladding technology to bring these components back to life—with enhanced performance and longer service life.
What is Laser Cladding?
Laser cladding is a cutting-edge repair process where we use a high-powered laser to fuse protective metal powders onto worn or damaged parts. This creates a new, corrosion-resistant surface without overheating the base metal.
It’s ideal for marine turbochargers and turbines, because it restores precise tolerances and protects parts from future corrosion—without replacing the entire unit.
Benefits for the Marine Industry
What We Recondition
INJEGOV SA regularly restores the following marine engine parts:
- Turbocharger Rotor Shafts
- Turbine Journals & Labyrinths
- Compressor Wheels
- Turbine & Turbocharger Casings
- Exhaust Side Components
These parts are reconditioned with precision laser cladding, followed by CNC machining and grinding to restore their performance and fit.

Typical Cladding Workflow at INJEGOV SA
- Surface prep:
Strip old coatings, polish journals/housings. - Laser cladding:
Apply specified powder and gamma-controlled track overlap using optimized parameters. - Inspection:
Check hardness, dilution via microscopic cross-sections. - Machining & Grinding:
Achieve final tolerances on journals, wheels, seals. - Final QA:
Verify balance, concentricity, and material integrity.
Why This Matters for Turbochargers & Turbines
| Parameter | Benefit |
|---|---|
| Fine Grain Clad | High hardness and wear resistance |
| Low Dilution | Strong bonding & minimal distortion |
| Precise HAZ | Heat control—protects base material |
| Optimized Overlap | Even coverage—smooth surface finish |
| FEM Modeling | Predictive control of residual stress |
