CTMA Project Completion: Kinetic Spray Metal Deposition

DoD Partners:  Oklahoma City Air Logistics Center; Marine Corps Maintenance Centers (Albany, Barstow); Navy Fleet Readiness Center East; Army Research Laboratory

Restoration and corrosion protection of metallic surfaces play a significant role in maintenance activities for both military and commercial applications. Costs associated with corrosion have been estimated to be a significant portion of the nation’s maintenance costs. For example, a recent study commissioned by the National Association of Corrosion Engineers (NACE) suggests that the national corrosion bill has an annual value exceeding $270 billion, thereby furthering the value of improvements in tech­nology to the commercial sector. Similarly, a GAO report issued in 2003 stated the Depart­ment of Defense (DoD) spent between $10 – 20 billion annually on corrosion prevention and mitigation. Clearly, technologies that improve corrosion resistance or reduce the amount of maintenance required by military and contract personnel have a great value to DoD.  Traditional corrosion countermeasures such as painting and thermal spraying are current “standards” for corrosion resistance in maintenance operations. These methods have several shortcomings:

  • Paints are prone to blistering and wear and are easy to strip

  • Paints do not necessarily provide galvanic protection

  • Thermal sprays are prone to defects in coating quality due to the melt process

  • Thermal sprays are limited in their portability and simplicity for field use due to safety and handling concerns around flames and oxy-fuel mixtures.

DoD has identified kinetic spray technologies as a new method to overcome a number of these traditional weaknesses. Kinetic spray deposition does not rely upon molten droplets that impact the surface and then solidify. Instead, the particles deform plastically on impact and cold weld to the surface. This results in a more uniform surface coating with less oxidation and higher density allowing for safer operation and good galvanic protection of the substrate.

The key benefits of the CTMA Kinetic Spray project realized were:

·        Aluminum kinetic sprays provide as good or better corrosion protection as current technologies such as paints and thermal sprays. These materials provide corrosion resistance equal to that of bulk aluminum when deposited on steels and magnesium alloys.

·        Aluminum kinetic sprays are an excellent filler material and show feasibility for in field repair applications. Adhesion strengths have been verified to be on par or better than thermal sprays but further develop­ment needs to be done to equal IVD coating strengths. A successful demon­stration of kinetic spray reparability was shown with a depot repair article as well as on Alclad repair tests. Further communi­cation between the depots, Boeing, and the sprayers must occur to bring this technology closer to commercialization for in-field and in-depot repair.

·        Generally speaking, smaller particle size and increased kinetic energy make the largest impact in deposition efficiency of zinc coatings on aluminum substrates. Similarly, a significant preheat for substrates and powders enables spraying hard materials such as nickel and increases deposition efficiencies and adhesion strengths.

·        Ultrasonic consolidation (UC) shows considerable promise in consolidating and compacting titanium kinetic sprays. Further validation on new UC operation regimes and different coatings should be continued to determine if this is a feasible second operation for creating difficult-to-spray coatings.

·        The technology is offered in a portable configuration by Centerline Limited (Windsor). This technology would provide intermediate and field operations with a low-cost, robust coating and repair method.

·        Helicopter gearbox cost avoidance of approximately $80K per year (average of four housings per year).

·        LAV fleet on Okinawa cost avoidance of one component is estimated to be approximately $100K per year.

CTMA Projects seeking interested participants:

  1. Centralized Fleet Automated Management System (CFAMS) – Debbie Lilu, 734-995-7038, debral@ncms.org   The proposed CFAMS solution targets maintenance prognostics and diagnostics automation, as well as provides a system solution to enable use-based maintenance, thereby increasing fleet operational readiness. Additionally, the system automates and enforces user preventative maintenance checks, and flags potential maintenance issues by level of severity; in which case, rendering vehicles with critical faults non-functional and immediately flagging the issue to maintenance personnel.
  2. Assembly Design and Documentation, Phase II - Tony Haynes, 734-995-4930, tonyh@ncms.org   Phase I of this project embedded GE’s MPAD (Maintainability, Planning, Analysis and Documentation) technology in UGS’ eM-Simulate software. The integrated technologies provide the necessary algorithms to automatically create and edit an intelligent assembly and disassembly sequence and work instructions based on complex geometric shapes plus engineering requirements for assembly (lubricants, torque, etc.). This technology has been tested by GE to verify the use cases that guided implementation but has not yet been validated for production use or for the creation of weapons system’s Technical Orders (TO).  The proposed approach is to validate system capabilities and gather metrics to quantify benefits by using the system in production or near production implementations.
  3. Configuration Management - Tony Haynes, 734-995-4930, tonyh@ncms.org  The proposed project would:
    • Leverage the common foundation of Teamcenter and the F101 engine to focus on process and data content rather than data format
    • Construct software development and test environments for OC-ALC and GE
    • Compare and reconcile the AF and GE e-BOMs
    • Define and create a Teamcenter based integration of OC-ALC and GEAE change process workflow
    • Run a trial based on one or more real but already completed Engineering Change Proposal (ECP) to test and iterate the system until it is stable
    • Use GE’s rich data structure as starting point for determining recommendations for future Air Force technical data requirements and for Teamcenter based workflow processes engineered to achieve maximum benefit from the new technology
    • Optionally, run a trial on one or more new ECPs
    • Document resulting process improvements (time, costs)
    • Create an implementation planning report that highlights issues, key points and so forth that will be necessary elements of a transition plan.
  4. Sense and Respond Logistics Development of Comprehensive Secondary Repairable Legacy Platform Readiness Capability (Light Armored Vehicle), Phase III – Mike Gnam, 734-995-4971, mikeg@ncms.org  In the next phase of this endeavor, PM-LAV intends to pursue a comprehensive approach to (1) incorporate RCM direction at the sub platform level; (2) expand and improve the quality and quantity of information gathered; (3) understand how Autonomic Logistics and GCSS-MC will support the future state of readiness decision making and (4) integrate data into a single all-inclusive environment.
  5. Inspection and Repair Preparation Cell (IRPC) - Bill Waddell, 231-264-9774, Wwadd49648@aol.com  Airframes and other weapon system entering the maintenance system contain increasing percentages of composite structures. Current inspection and repair processes are performed manually. Inspections are subjective with little historical tracking of repairs. The team has selected the C-130 Radomes, F-15 Radomes and F-15 Speed Brakes, maintained by the Warner Robins ALC, as typical of the need. These are large complex composite structures, with a high volume repair rates, requiring multiple setups and transportation between locations. This project will demonstrate utilization of an automated work cell with the capability to perform multiple operations with a single set up, eliminating the need to transport parts to separate locations, between operations, while providing consistent disciplined automated approaches to the depot inspection and repair methodologies, versus the current “subjective” manual approaches and processes.
  6. Automated Process and Inspection Guide (AP & IG) – Debbie Lilu, 734-995-7038, debral@ncms.org  The AP&IG project will eliminate the messy manual paper process and replace it with mobile data capture devices combined with COTS software to guide the inspector through the inspection. It will impact the inspection process on four levels (1) Process (2) Personnel (3) Management and (4) Analysis.
  7. Oil Assessment Devices, Phase II – Debbie Lilu, 734-995-7038, debral@ncms.org  A rugged field portable FTIR has been developed for in field lubricant testing. The device incorporates software and hardware that provides rapid assessment of key lubricant parameters such as water, soot and coolant content. Identification of proper lubricant application is also a feature. The varied assets (tanks, LAV, aircraft) and lubricant types used within DoD require different protocols for testing which are currently unavailable. To successfully implement in field analysis across DoD, field testing is required to develop these protocols for the different assets and lubricant types. Equipment that test other parameters such as the thermal properties and viscosity of lubricants are also being made available. Currently all are used as separate devices generating separate reports.
  8. Aircraft Panel Replacement – Bill Waddell, 231-264-9774, Wwadd49648@aol.com  Utilizing advanced inspection technology, the holes on an aircraft panel adjacent to the panel to be replaced are mapped and a surface data model created with precise hole locations. The data model will then be used to create a program to drill the holes. The panel will then formed and assembled to the aircraft.
  9. Replacement for Hexavalent Chromium in Surface Finishing Process Phase II
    – Paul Chalmer, 734-995-4911, paulc@ncms.org.  The proposed technology is being positioned as a drop-in replacement for currently practiced hexavalent chromium electroplating, subject to currently acceptable MIL SPECS for hard chrome electroplating.
  10. Modernization of Nickel Electroplating at Depots – Paul Chalmer, 734-995-4911, paulc@ncms.org.   The objective of this proposed project is to introduce new nickel electroplating tooling into Department of Defense maintenance activities, including no-mask tooling, auxiliary anodes, innovative racks, partial immersion plating, and solution pumping.
  11. Enhanced Wiring Integrity System Phase II – Lee Patch, 734-995-4972, leep@ncms.org  Phase I of the Electrical Wiring Integrity Systems Program (EWIS) demonstrated the potential that can be realized by effective wire testing and maintenance.  Phase II will extend EWIS into other DoD applications that can benefit from the technology. 
  12. Laser Projection of Camouflage and Stencil Patterns – Connie Philips, 386-445-2785, conniep@ncms.org   Application or chalking of camouflage and stencil patterns is a manual method dependent on the skill of the technician. This project aims to reduce the time required to chalk a system and to change to another system is required to make the painting operation more efficient and to reduce the disruption of the product flow while increasing quality.  
  13. Smart Machine Phase III – Tony Haynes, 734-995-4930, tonyh@ncms.org   This effort will deploy ‘Smart Machine’ technologies to equip different machines from different manufacturers with integrated plug-and-play condition logging capabilities that support the operating, processing, and maintenance teams to effectively optimize factory asset performance over time, and lay the foundation for additional developments, such as predictive maintenance. 
  14. Metal Finishing Development Program – Bill Chenevert, 734-995-7989, billc@ncms.org  This project will develop a unified DOD-wide metal finishing (electroplater) workforce training program. The self-study PC based program (i.e. e-learning or computer based learning) would consist of modular lessons that cover common metal finishing processes. Specific processes include, but are not limited to, chromium, cadmium, nickel, copper, and silver plating, aluminum anodizing, and conversion coatings (for cadmium, aluminum, and magnesium).
