Research abstract
This proposal responds to the problem of fretting and galling occurring at the interface between steel inserts and A357 aluminum alloy gear box housings. UCT Defense proposes to apply Boronizing and/or Ni-B surface modifications to eliminate corrosion, fretting, and galling and to allow the steel inserts to be removed from the design, which will also reduce the weight of the system. The innovation that responds to this problem is an advancement in engineered surface finishing for galling, fretting, and corrosion resistance of aluminum alloy gearbox housings using the UltraCemT family of nickel boron coatings and/or a novel boronizing surface modification.
