Longer Life Barrels with Copper Titanium alloy
Pahwa MetalTech manufactures HVOF thermal spray barrels in QTi Copper Titanium alloy, engineered for extended operational life under severe thermal spray operating conditions. In HVOF systems, the barrel is continuously exposed to high-temperature combustion gases, abrasive powder flow, and repeated thermal cycling, all of which accelerate internal wear and dimensional degradation.
Copper Titanium provides a significant advantage in these conditions through its combination of high thermal conductivity, improved hardness, and excellent resistance to thermal fatigue. The alloy helps dissipate heat efficiently while maintaining structural stability under continuous high-temperature operation. This reduces premature bore wear, geometry distortion, and performance instability commonly associated with lower-performance materials.
Longer barrel life directly reduces replacement frequency, minimizes production downtime, and helps maintain consistent spray characteristics over extended operating cycles. For high-volume coating operations, maintaining stable internal barrel geometry is critical for preserving combustion stability, particle acceleration, and coating consistency.
High Wear Resistance for Demanding HVOF Applications
HVOF barrels operate under intense erosive loading generated by supersonic powder particles travelling through the barrel at extremely high velocities. Over time, abrasive wear inside the barrel can alter internal dimensions, affect gas flow behaviour, and reduce coating process stability.
Pahwa MetalTech manufactures Copper Titanium HVOF barrels with a strong focus on wear resistance, dimensional accuracy, and long-term process reliability. The Copper Titanium alloy offers substantially better wear resistance compared to conventional copper-based materials while retaining the thermal conductivity required for efficient heat management in HVOF systems.
Combined with precision machining and controlled internal bore geometry, the material helps maintain dimensional stability and internal surface integrity over longer service intervals. This contributes to stable combustion characteristics, consistent powder acceleration, improved coating repeatability, and reduced maintenance intervention in demanding industrial thermal spray operations.
Key Features
Uniform Coat
A good coating is always highly dependent on barrel material to maintain a thick and uniform coating process.
Temperature Control
Adequate temperature control of the Nozzle is necessary within and outside the barrel to deliver high spray rates.
High Surface Quality
Efficient, Combustion and particle heating helps in adequate delivery of the deposition material, in producing high quality coating.
Durability
Conventional Copper Alloys have low wear resistance to sustain the velocity and pressure required to obtain quality coating consistency.
End of life disposal
Nozzle must be made from Non-hazardous and Recyclable material, to ensure it is environmentally friendly. QTi® meets these requirements fully.
