2. Air Force Corrosion Preventionand Control Office Mission
Ensure the Air Force has an effective program
to prevent, detect, and control corrosion
and minimize the impact of corrosion
on Air Force combat capability.
3. Air Force Corrosion Preventionand Control Office Leadership of the Air Force Corrosion Community
Engineering Responsibility for 8 AF-Wide Technical Orders
Engineering and Technical Assistance
Corrosion Surveys of Major Commands and Weapon Systems
Weapon System Corrosion Prevention Advisory Boards
Host Annual USAF Corrosion Conference
Evaluate Corrosion Control Technologies
4. Powder Coatings Prototype line at Robins AFB, GA for validation on a/c fire extinguishers, gas bottles
Modular facility to test at Hill AFB on aircraft wheels
Will operate parallel to existing line--test w/o impact to production
Evaluating UV-cured powder coating process for aircraft wheels @ Randolph AFB, TX
Selecting material, determining process parameters
Evaluating available materials for field-level touch-up of powder coatings
Repair capability necessary to deploy PC
PC already in USAF use on vehicles and SE.
5. Metal Wire Arc Spray Metal Wire Arc Spray (MWAS) --zinc/aluminum coating
Commercial process: MWAS in use for antenna towers in AF Space Command
Project to test feasibility on AF Space Command launch towers
Implemented MWAS at Blue Grass Army Depot for AF bombs
Prototyped on AF Cargo Loaders
Supporting PACAF effort to sustain facilities at Guam and Kadena AB Japan
6. X-It PreKote Field Testing X-It is a pre-paint surface treatment for aluminum
Non-chromated, promotes adhesion
Potential to replace Alodine chromated conversion coating
In use at Ogden Air Logistics Center on F-16s; tested on T-38s
More data needed before AFCPCO recommends AF-wide and incorporates in T.O. 1-1-8 (technical order for painting)
Six-year test to provide confidence on more substrates
Applied to two A-10’s (Davis-Monthan AFB, AZ and Pope AFB, NC) and 2 C-130’s (Little Rock, AR, and Puerto Rico) in 2001
Latest inspections Sep 02; excellent performance to date
Weapon system program offices may authorize sooner if desired
Testing begun on magnesium aircraft wheels and T-1’s
All tests with chromated primer; any approval will be contingent on use of chromated primer
7. ACC Corrosion Survey Surveyed Air Combat Command corrosion program Sep 02
Assess overall health of command program (equipment, processes, hazmart, T.O.s, training, QA, scheduling) -- NOT an inspection
Coatings-related findings:
Corrosion shops using proper materials
Excellent condition of aircraft
One exception; structural patches
Recommend Sempens or brush/roller
Some use of unauthorized paints, especially on ground support equipment
8. New Chemical Paint Removers Purchase Description (PD) used by Warner Robins Air Logistics Center (WR-ALC) for non-chlorinated solvent type remover – primarily benzyl alcohol based
Evaluating new hydrogen peroxide-based removers (lab and on-aircraft)
better performance than other env. compliant removers, same PPE
fails tests for magnesium corrosion, pH, viscosity, shelf life.
AFCPCO approved for USAF use with restrictions:
Depot-level use ONLY (not field units)
Must be approved by weapon system engineering authority
Must be used within 3 months
DRAFT Air Force-wide version of PD in work; will include hydrogen peroxide type activated removers
9. Our Emphasis is Performance Our primary concern is corrosion prevention and control, not environmental compliance
Our metric: best performance while complying with environmental restrictions
New materials and processes require:
Disciplined, legitimate testing
Anecdotal experience not sufficient
Vendor claims not sufficient
Environmental compliance alone not sufficient
Technical order authorization
Weapon system program office is final authority
