Research Institution
The Navy is developing liquid metal combustion as the power source for the propulsion systems of several advanced underwater vehicles. Parts made from Hastelloy alloy are used to contain the liquid metal reaction. This environment is extremely hostile: molten lithium at 2OOO-3OOOF causing corrosion, erosion, and/or melting of the Hastelloy alloy, and often failure. In this Phase I program, Ultramet proposes to apply innovative materials and processing to demonstrate the viability of coatings for the protection of Hastelloy alloys from the effects of molten lithium at 2OOO-3OOOF. The overall goal of the program is to extend the operating range and survivability of advanced underwater vehicles powered by liquid metal combustion. To ensure success, Ultramet has teamed with the Garrett Fluid Systems Division (GFSD) of Allied-Signal Corp., a leader in liquid metal combustion engines.
