Plasma Projection
Plasma Spraying – Molybdenum (Mo)
Plasma spraying is a high-performance process in which molybdenum (Mo) is sprayed at temperatures exceeding 15,000°C and at a speed of 500 m/s using a plasma torch. This coating is particularly prized for its excellent coefficient of friction, which reduces wear while preserving opposing parts. Thanks to its exceptional adhesion, molybdenum provides long-lasting and effective protection against wear and corrosion.
Benefits
– Friction reduction: Improves part performance while minimizing wear.
– Anti-corrosion properties: Provides effective protection against corrosive environments.
– High thermal resistance: Withstands high temperatures without compromising coating quality.
Features
– Friction resistance: Excellent performance under friction conditions, limiting component wear.
– Corrosion resistance: Highly effective against corrosive attack, extending the service life of treated parts.
– Coating thickness: From 0.1 to 0.3 mm, providing robust protection without adding weight to components.
– Surface finish: Uncoated or Ra < 0.2 µm, providing a high-quality finish for precision applications.
– Maximum operating temperature: Up to 350°C, ideal for high-temperature environments.
– Hardness: Can reach 500 HV depending on the powder composition, ensuring enhanced wear protection.
Typical application
Plasma-sprayed molybdenum is particularly suitable for industrial applications where resistance to wear, friction, and corrosion are crucial. Common applications include:
– Bushings
– Mechanical seals
– Couplings
– Paper rolls
– Discs
– Clutches
– Guides
Conclusion:
The molybdenum plasma spray process is an ideal solution for applications requiring high resistance to friction, corrosion, and temperature. Thanks to its exceptional properties, it extends the service life of mechanical parts while ensuring optimal performance in demanding environments.
