  • Comparative Study of Military Specified General Purpose Synthetic Aviation Lubricants in Regards to Wear Performance, Corrosion Prevention and Salt Water Resistancy (.pdf)
    MIL-PRF-81322 has been used for many years as a wide temperature (-54 to 177ºC) aviation lubricant. Recently, MIL-PRF-32014 has shown improvement with enhanced wear and corrosion resistance. Various military aircraft component testing will be discussed, both bench and field. A lubricant comparison
  • Good grease, good landing
    in both defensive and offensive measures. No longer in production, new parts need to be custom fabricated, thus the military search for better corrosion protection. Bearing cup assembled with MIL-PRF-81322 grease (top) showed extensive corrosion after the 10-day wash test and actually seized
  • Simultaneous Metal Treatment and Hexavalent Chrome Reduction
    A well known military metal finishing operation in Pennsylvania was having trouble treating hexavalent chromate rinses that also had cadmium in them. Our team of experts set the system up to treat both the hex chrome and cadmium bearing rinses in the same tank. The Aquapure I-300 was used
  • Polyimide composites challenge metals
    A variety of polyimide composite materials produce cost-effective alternatives to cast-metal parts. Edited by Jean M. Hoffman The bushings, bearing pads, and splines in the 10-stage, high-pressure compressor of the Rolls-Royce BR710 turbofan engine are made from Vespel polyimide. These parts
  • Slick as a whistle, hard as a rock
    Nibron, a coating of nickel, thallium, and boron, improves wear and hardness on aerospace and automotive components. Several military jets, including the Air Force's new fighter, the F-22 Raptor, have engine components coated with Nibron to reduce wear. This chart shows that Nibron is harder than
