eGun™ HVOF Spray Gun

About eGun™ HVOF Spray Gun

Ethanol-fueled HVOF Technology THE NEXT STEP IN HVOF TECHNOLOGY

The eGun™ is a liquid fuel HVOF torch that utilizes ethanol as its fuel. The eGun™ is capable of operating at combustion chamber pressures up to 13 bar (188 PSI). This is 3 to 5 bar (43 – 73 PSI) greater than conventional kerosene HP-HVOF systems. It has been shown that higher combustion chamber pressure generates higher flame velocity which in turn generates higher particle velocity. Higher particle velocity results in improved coating density and better overall coating integrity. It is also very easy to run at low flame velocity for slow and hot parameters to produce very good bonding (rough) flash coats.

Features & benefits the eGun™ - ethanol-based liquid fuel HVOF Technolgy:

- Larger window of operation vs kerosene, thus better control over the balance between the kinetic and thermal energy of the particles. - 30%-50% reduction in oxygen usage - Up to 50% reduction in required cooling power - No ash formation - Less toxic fumes - Environmentally friendly - Consistent fuel - Easy smooth system starts and ramp-ups - Ability to run very fuel rich, creating new coatings and application opportunities - High coating integrity and uniformity. - Higher combustion chamber pressure results in higher particle speed. - Coating exhibit excellent wear resistance. - Superior microhardness compared to other thermal spray technologies - Very high bond strengths, typically exceeding 80 MPa (10000 psi) - High-density coatings with minimal porosity - Low impurities and oxides levels - Compressive stresses in the coating. - Thick coatings, up to or exceeding 6 mm (0.25 inch) are possible - Smooth “as-sprayed” surface finishes - Dual port, radially fed powder injection - Simple design resulting in low and easy maintenance. - Remote, Safe, Reliable and ignition design. - Machine-mount for use with robots and traverses systems
