Upcoming Changes in Sustainment and ASETSDefense assistance
Current F-35 Pollution Prevention Activities
Implementing HVOF WC-Co-Cr and AlumiplateTM for Landing Gears
Implementing New DeftNon-Chrome Primer for
Interior/Exterior Use
Testing AlumiplateTM to Replace Nickel/Cadmium
on Metal/Composite Electrical Connectors
Aqueous Nanocrystalline Co-P to
Replace EHC and TDC for Actuation Systems
Cu-Be BushingReplacement Material
Various Vendors Testing New Coatings and High Strength SS
Aggressively Investigating New Materials
What is new? – F-35 STOVL
C-fiber composite skinStainless & Ti fastenersNitronic 60 bushings in place of CuBeOn-board generators for oxygen and fuel tank inertingElectro-hydraulic actuatorsNon-ODC cleanersCr & ODC-free sealants
LO coatingsHVOF WC-CoCr
Landing gear, actuators, etc
Cr-free primer (Deft 44GN098)
OML and interior baysAlumiPlate in place of Cd (landing gear, electrical connectors)
Still have some CdTFSAA
Probably coming on F-35 during LRIP
Cold spray Al for Mg gearbox repairChromate-free fuel tank coatingsCr-free sealantsnCo-P ID coatings (hydraulics)Non-Ni gap fillers
Coming on helicopters and other systems
ZnNi in place of CdTagnite, brush Tagnite on Mg gearboxes - SikorskyCr3+ and non-Cr Al, Mg treatmentsBSAAPre-coated wet-install fastenersUV cure topcoatsPowder coats
A-64 Apache
HVOF WC-CoCr repair of static mastCold spray Al mast support repairNon-Cr primer, Deft 44GN098 (Apache)
Various OEM changes - Boeing
CH-46– ZnNi in production as cadmium alternative
CH-46 rotor hub, swashplate brgs (galvanic protection)Very difficult to get right
CH-47– HVOF WC-Co coating qualified for Slider Guide– Replacement for hard anodizing
AH-64– HVOF WC-CoCr Repair of Tail Rotor Static Mast
V-22– Ion nitriding of refueling probe components– Solved wear, galling
How can depots adopt best repair technologies with minimum cost, time, frustration?
Keep track of all these new materials and coatings and related technologiesFind the right MRO technologies to maintain themQualify new technologies
Find all the existing dataAcquire the rest
Install new systemsDevelop maintenance specsTrain operators and engineers
ASETSDefense is set up to help with all this
What is ASETSDefense?
Funded by SERDP/ESTCPSupport implementation of clean coatings and surface treatments, including alternatives to
Hard chrome plateCd plateHigh VOC paintsChromates
pretreats, primers, sealants, anodize, etc
On-line information and engineering data resource for DoD organizations and contractors
Why ASETSDefense?
HCAT program showed the importance of Users getting together to share experienceEveryone having access to all the engineering data
ASETSDefense is reproducing this approach on a broader scale. We can help provide whatever will make it easier and more efficient to implement clean technologies in DoD and the supplier base

Examples of assistance ASETSDefense can supply to depots
CoatingsWe know all types of coatings and surface treatments
Electroplating, electrophoresis (e-coat)Thermal spray and cold sprayCVD, PVD, IVDHeat treatmentsLaser treatmentsSermeTel alternativesCd, hard chrome, chromate alternatives
Related technologies3-D direct digital manufacturingRebuilding and repair
Laser welding and claddingOther microwelding methods
StrippingLaser, pulsed water jet
NDI
Approach is to put together the right team for the job to supply anything from analysis to implementation
Examples of projects
Technology analysisWhat does VLCOE need over the next 10 yrs?What COTS technologies are available?What developments are needed?What will it take to get everything in place, in time?
