Frequently Asked Questions

What is HVOF coating used for?

HVOF (High Velocity Oxygen Fuel) is used to apply wear-resistant coatings such as tungsten carbide and chrome carbide on components in oil & gas, aerospace, and manufacturing.

How does HVAF differ from HVOF?

HVAF uses compressed air instead of oxygen, resulting in lower oxide content and higher particle velocity, ideal for corrosion-resistant coatings.

Can you customize equipment?

Yes, we offer customized thermal spray systems and processing services based on specific client requirements.

Do you provide technical support?

Absolutely. We offer full lifecycle support including installation, training, maintenance, and troubleshooting.
