Advancing Additive Repair Technologies and Cold Spray for Sustainment of Maritime Assets – Phase II

NCMS Project #: 142021

Problem: Commercial maritime assets are globally deployed in demanding conditions, placing unique constraints on an organization’s ability to perform maintenance and sustainment operations while underway or in shipyards. The U.S economy relies on maritime fleets to deliver both finished goods and raw commodities vital to a multitude of commercial industries.  Implementing the ability to make repairs while underway will give vessels the capability to continue towards port with critical cargo, and to accomplish their missions in lieu of being held in a repair facility.

Benefit: While this initiative focuses on ships, the results will be applicable to many other industries, such as truck transport, train, aircraft, and other situations where repair adversely affects deliverables and time schedules.  By acting as a testbed, the U.S. Navy is providing a roadmap for the successful implementation of cold spray technology onboard vessels and across a wider variety of vehicle fleets.

Solution/Approach: Phase II will build upon the initial successes of Phase I and strive to refine new specialty cold spray powders that can be fielded and utilized as a portable and hatchable technology while underway for in-situ repairs.  Additionally, expanding the testing of this technology for use in structural repairs has the potential to significantly improve operational readiness across the entire fleet, and will help to validate applicability across numerous other platforms, ranging from aircraft to ground vehicle fleets.
