Fixed and Portable Kinetic Metallization Systems for Dimensional Restoration Repairs

Dimensional restoration repair of salvageable and consumable submarine and shipboard components have the potential to significantly reduce maintenance cost and turn around times for the Navy Fleet Readiness Centers and Intermediate Maintenance Facilities. Trident Trim Pumps used by Naval Undersea Warfare Center provide an opportunity to demonstrate these savings on pump lobes, cones, and motor casing components damaged by corrosion or wear. Kinetic Metallization (KM) is a low temperature impact spray deposition process that enables dimensional restoration repairs without affecting the heat treatment and temper of the parts. The deposition process uses a low-pressure (<150 psig) sonic nozzle design that provides comparable performance of supersonic high-pressure cold spray systems at a fraction of the cost. Inovati is the sole US manufacturer of fixed and portable KM tools that meet MIL-STD-3021 for restoration repairs of military components. The objective of the proposed research is to investigate and develop conceptual designs and powder feedstock using Kinetic Metallization technology and tools to enable dimensional restoration repairs of the Trident Trim Pump components as well as and other high value submarine and shipboard components.
