Title: COMPATIBILITY OF MULTI-LAYER, ELECTRICALLY INSULATING COATINGS FOR THE VANADIUM-LITHIUM BLANKET

Abstract

The objective of this work is to demonstrate that a multi-layer, electrically insulating coating will acceptably reduce the magneto hydrodynamic (MHD) pressure losses in a lithium-cooled blanket. Coatings of Er{sub 2}O{sub 3} or Y{sub 2}O{sub 3} with an overlying coating of vanadium have been fabricated by physical vapor deposition. Coatings have demonstrated acceptable as-received resistivity at 800 C in vacuum and at 600 C in contact with Li. When the Y2O3 coating was completely covered with a 10 {micro}m vanadium layer, it survived exposure to Li for 100 h at 800 C without degradation. The interaction between V alloys and Li at {le} 800 C is now the critical compatibility issue and a loop test is being constructed. New ceramic materials based on the Y-Ti-O system also are being explored.
