Gulhfi has developed the Debye-Larmor cascade gun family based on F4 gun technology.

The peculiarity is that the Debye-Larmor gun is a modular plasma arc length this allows to master the output power, plasma gas velocity and enthalpy with only argon plasma gas.

Ceramic and metallic powders melting can be mastered. 

Debye-Larmor plasma gun can be used in Atmospheric Plasma Process as well in Vacuum Plasma Process. In case of Vacuum Plasma Spray process for some specific Debye-Larmor guns configuration no specific external ignition unit is needed, the gun can be simply installed on to the plasma spray system and is ready to run. 

The advantage of the of Debye-Larmor guns family are:

-          Simple and robust modularity of the plasma arc length

-          Hydrogen and Helium arm (free) coating application

-          Controlled and very low plasma voltage fluctuations

-          Reduced wear gun wear and improved gun robustness

-          Can be installed in any type of plasma spray system

Guhlfi expert team will come on site to install and to help you to improve your coating properties.
