  1. Hard Chrome Alternatives Team Joint Group on Pollution Prevention Propulsion Environmental Working Group PROGRAM REVIEW MEETING 1-2 April 2003 San Diego, California

  2. Acknowledgments -Principal HCAT Program Sponsors • Department of Defense Environmental Security Technology Certification Program • Department of Defense Joint Group on Pollution Prevention • Department of Defense Propulsion Environmental Working Group

  3. HCAT Program OBJECTIVE: Conduct research/development or demonstration/validation on advanced surface engineering technologies that will eliminate or mitigate environmental problems while improving materials performance that will lead to reduced life-cycle costs in military weapons systems • HVOF thermal spray coatings to replace hard chrome plating on external surfaces (approx.80% of total workload) • Plasma spraying using miniature guns for replacement of hard chrome plating on internal surfaces • Electrospark deposition for localized repair of coatings or non-coated components New proposals being generated to respond to DOD needs

  4. HCAT Projects Landing Gear: • ESTCP funding ended in FY02 • Cost and Performance Report completed and submitted to ESTCP Program Office (approx. 30-page document summarizing materials and component testing plus cost/benefit analysis) • Air Force making major commitment to implement HVOF at Ogden ALC for chrome replacement • Navy flight testing and Lockheed-Martin rig testing on P3 should lead to chrome replacement on Navy land-based aircraft • Canadian and U.S. LG OEMs moving towards implementing HVOF • Issuance of two AMS specs on powder and deposition

  5. HCAT Projects Propeller Hubs: • ESTCP funding ended in FY02 • Cost and Performance Report completed and submitted to ESTCP Program Office (approx. 30-page document summarizing materials and component testing plus cost/benefit analysis) • Materials and rig test favorable; engine test in progress and looks favorable; six-month flight test scheduled • Anticipate putting HVOF into production on components at NADEP-CP and Warner-Robins ALC

  6. HCAT Projects Gas Turbine Engines: • ESTCP funding through end of FY03 • Materials testing to be completed by end of calendar 2003 • Successful TF33 accelerated engine test completed with HVOF WC/17Co-coated components • Oklahoma City ALC moving towards implementing HVOF into production on all engines • NADEP-JAX has HVOF in production on TF34

  7. HCAT Projects Hydraulic Actuators: • ESTCP funding in FY03 and FY04 • Component testing in progress at NAVAIR Pax River; Navy moving towards qualifying HVOF coatings on actuator components • AF cognizant activity conducted survey of all chrome-plated actuators; initiated delta qualification on selected actuator systems • Materials testing (Joint Test Protocol) to support component testing still being finalized • Anticipate stakeholders meeting (DOD, OEMs, subcontractors) in summer 2003

  8. HCAT Projects Helicopter Dynamic Components: • ESTCP funding in FY04 and FY05 (zero in FY03) • Sikorsky and Boeing Philadelphia being put under contract to conduct assessment of chrome plating on HDC and define materials and component test requirements • Anticipate stakeholders meeting in Fall 2003 Plasma Spraying on Internal Surfaces: • SERDP funding in FY04 (zero in FY03) • Coatings successfully deposited on inside surface of specially designed cylindrical specimen holder using miniature plasma spray guns • Materials testing in progress • Exploring transition opportunities to depots

  9. HCAT Projects Electrospark Deposition (ESD): • ESTCP funding in FY03, FY04, and FY05 • ESD systems acquired and delivered to NADEP-North Island, Oklahoma City ALC, and Anniston Army Depot • Work in progress at Advanced Surfaces and Processes, NSWC Carderock, and Edison Welding Institute on repair of chrome plate and base materials
