HaloJet ID HVOFTM System

Description & Characteristics


For our aerospace and defense clients seeking an improved inside diameter coating or those with a need to meet regulatory requirements (such as REACh) mandating elimination of hexavalent chrome from production processes, Kymera’s HaloJet ID HVOFTM coating system is the solution.

The HaloJet system uses state-of-the-art material processing and Kymera’s Adiabatic Flame Technology to maximize coating density and heat transfer to the coating alloy particle while minimizing heat transfer to the substrate material. These unique features allow the HaloJet application system to coat internal surfaces as small as 2.5” (63mm) while keeping substrate temperatures below 300°F (150°C), a highly effective and proven solution for landing gear coatings.

Kymera offers the base HaloJet system for clients that want to independently manage implementation, or a turnkey solution with engineering, procurement and commissioning service, including core infrastructure selection and installation, provided by Kymera.

Kymera doesn’t just develop and sell equipment, we’re a comprehensive service provider with extensive experience operating the HaloJet system for a broad range of end-user applications.  Clients seeking a turnkey solution can further take advantage of our operational experience and engage Kymera in developing and optimizing automation programs, maskings and fixtures to ensure both an effective and efficient commissioning and ramp-up process.


Features & Benefits

Novel fuel/gas/oxidizer and combustion chamber geometry
  • Maximum amount of thermal enthaply released prior to powder introduction reduces thermal energy transfer to substrate
Proprietary nano HVOF alloys
  • Small particle size allows high kinetic energy creating high bond strength
Combustion power level of 25kW
  • Power level lower than competition (as compared to competitor range of 60 - 130 kW)
  • Minimizes thermal energy transfer to substrate allowing application to temperature sensitive alloys
Robotic spray cell
  • Repeatable coatings on a wide variety of component sizes and geometries improves resultant quality
Rotary Jet gun head system
  • Internal ventilation and dust extraction is more effective than stationary systems improving coatings quality
  • Allows blind hole coatings (i.e. landing gear)
  • Permits coatings of eccentric bores, asymmetric parts, components and attachments
Rotary speeds up to 300 rpm
  • Can maintain consistent coating thickness on ID's as small as 2.5" (65mm)
