Systems & Capabilities

As one of the only companies operating both high pressure and medium pressure systems, Moog has the ability to spray a wide array of coating materials. With a variety of materials comes a variety of critical velocity requirements… the more pressure, the more velocity. Our wide array of equipment coupled with our extensive range of coating materials ensures we meet your unique repair requirements.

Coating Powders Commonly Used:

  • Aluminum
  • Brass
  • Bronze
  • Copper
  • Inconel
  • Monel
  • Nickel
  • Niobium
  • Silver
  • Steel
  • Stainless Steel
  • Tantalum
  • Tin
  • Titanium
  • Zinc
  • Zirconium

Cold Spray repair is generally performed using low, medium or high pressure systems, through the use of a handheld, portable system or a stationary system in a ventilated work chamber.

Low or Medium Pressure Systems:
 These systems are used in the application of lighter materials. Low or Medium pressure Cold Spray systems are typically much smaller, portable, and are limited to 300-600 m/sec particle velocities. Metallic powder is injected after the nozzle throat (diverging section) to avoid nozzle erosion. Low or medium pressure systems generally utilize readily available air or nitrogen as propellant gases.

High Pressure Systems:
 These systems are used in the application of more dense or heavy particles. High pressure Cold Spray systems utilize higher pressure gases, are stationary, and are typically generating particle velocities of 800 -1400 m/sec. Metallic powder is injected before the nozzle throat after which the gas is expanded through a converging/diverging nozzle. Lower weight gases, such as nitrogen or helium, are the preferred propellant gases.
