ARL Center for Cold Spray

2014 Defense Standardization Program Achievement Award

A U.S. Army Research Laboratory technical team was recognized by the Defense Department on March 12, 2009, for its role in the development of the specification, MIL- DTL-32495, a Manufacturing Process Standard, entitled: Aluminum-Based Powders for Cold Spray Deposition. The winners led an international effort to develop a new specification that covers the requirements for procuring aluminum and aluminum-based alloy powders. These powders will be used to produce deposits utilizing a cold spray materials deposition process for the purpose of parts repair, coatings, or fabrication of freestanding structures. The 2014 Defense Standardization Program (DSP) Achievement Award was presented to the ARL team by DoD's Standardization Program Office.

2013 Mantech Program of the Year Award

Restoration of Aerospace Parts by cold spray. Several flight critical aerospace components made from of aluminum, titanium or magnesium alloys cannot be repaired using convention repair processes and must be removed from service, costing the DoD several million dollars in replacement parts. Many of these components have long lead times and in some cases, there are no replacement parts in inventory. Working in concert, the Navy, Army, and the OEMs (Applied Research Laboratory/Penn State (ARL/PSU), the U.S. Army Research Laboratory (Army ARL) and NAVAIR's Pax River, FRC East, FRC South West) developed test protocols, validation and acceptance requirements, process procedures, and inspection requirements. The cold spray process has been implemented in Army, Navy, and commercial facilities. Several aerospace components are currently being repaired to include the B-1 FEB Panel, B-1hydraulic Lines, F/18 AMAD Transmission housing and the UH-60 magnesium gear box sump. Several other repairs are being developed transitioned upon validation.

2012 ESTCP Program of the Year Award

The project team developed a cold spray process that involves accelerating aluminum alloy particles to high velocities and impacting them on the surface of the magnesium alloy components. In their project, the cold spray process was demonstrated and validated to be a cost-effective, environmentally acceptable technology that could provide surface protection, as well as a method for restoring magnesium components that have been removed from service. The process can be incorporated into manufacturing and portable systems can be developed for field repair. A cold spray demonstration facility was established at the Navy's Fleet Readiness Center -- East, in North Carolina (formerly the Naval Air Depot Cherry Point). This project resulted in the implementation of cold spray by Sikorsky Aircraft Company. Both Sikorsky and the Army Program Office for the UH-60 Blackhawk helicopter have approved cold spray for use as a repair technology for one UH-60 magnesium component; with other approvals expected soon.

2008 Defense Standardization Program Achievement Award

A U.S. Army Research Laboratory technical team was recognized by the Defense Department on March 12, 2009, for its role in the development of the specification, MIL-STD-3021, a Manufacturing Process Standard, entitled: Materials Deposition, Cold Spray. The 2008 Defense Standardization Program (DSP) Achievement Award was presented to the ARL team by DoD's Standardization Program Office. The DSP mission is to identify, influence, develop, manage, and provide access to standardization processes, products, and services for Warfighters and the acquisition and logistics communities. In addition, the program promotes interoperability and assists in reducing total ownership cost and in sustaining readiness.

2007 Defense Manufacturing Excellence Award

The Defense Manufacturing Excellence Award is given annually to a small working group in the defense manufacturing community. The winner is acknowledged as having made outstanding contributions to furthering manufacturing science and technology in the United States over the past fiscal year. The National Center for Manufacturing Sciences (NCMS) managed a cross-industry collaborative team that developed the use of cold spray for corrosion control. The methods developed will impact Department of Defense by significantly reducing corrosion related maintenance across all military services. The project participants included all the branches of the armed services: The Army ARL, Navy, Air Force and Marines, and the cross-industry companies: The Boeing Company, Delphi Corporation, Ford Motor Company, CenterLine Ltd. and Solidica.
